Issue 10/06 1.1 The MICROMASTER 440 The MICROMASTER 440 are frequency inverters for speed and torque control of three-phase motors. The various models available cover the performance range from 120 W to 200 kW (for constant torque (CT), alternatively up to 250kW (for variable torque (VT)). The inverters are microprocessor-controlled and use state-of-the-art Insulated Gate BipoIar Transistor (IGBT) technology. This makes them reliable and versatile. A special pulse-width modulation method with selectable Pulse frequency permits quiet motor operation. Comprehensive protective functions provide excellent inverter and motor protection. With the factory default settings, the MICROMASTER 440 is suitable for many variable speed applications. Using the functionally grouped parameters, the MICROMASTER 440 can adapted to more demanding applications. The MICROMASTER 440 can be used in both 'stand-alone' applications as well as being integrated into 'Automation Systems'.

MICROMASTER 440 Operating Instructions 6SE6400-5AW00-0BP0 33 2 Installation Issue 10/06 2.4.1 General WARNING The inverter must always be grounded. If the inverter is not grounded correctly, extremely dangerous conditions may arise within the inverter which could prove potentially fatal. Operation with ungrounded (IT) supplies Filtered The use of filtered MICROMASTER 4 drives on unearthed mains supplies is not permitted. Unfiltered In the case of non-grounded networks, the 'Y' capacitor of the device must be made ineffective. The procedure is described in Appendix D. If the MICROMASTER is to remain in operation in non-grounded networks when a ground fault occurs during the input or output phase, an output reactor must be installed. Operation with Residual Current Device (Frame Sizes A to F) If an RCD (also referred to as ELCB or RCCB) is fitted, the MICROMASTER inverters will operate without nuisance tripping, provided that: ¾ A type B RCD is used. ¾ The trip limit of the RCD is 300 mA. ¾ The neutral of the supply is grounded. ¾ Only one inverter is supplied from each RCD. ¾ The output cables are less than 50 m (screened) or 100 m (unscreened). NOTE The residual current operated circuit-breakers used must provide protection against direct-current components in the fault current and must be suitable for briefly suppressing power pulse current peaks. It is recommended to protect the frequency inverter by fuse separately. The regulations of the individual country (e.g. VDE regulations in Germany) and the regional power suppliers must be observed! MICROMASTER 440 Operating Instructions 34 6SE6400-5AW00-0BP0 Issue 10/06 2 Installation 2.4.2 Power and motor connections WARNING The inverter must always be grounded. ♦ Isolate the mains electrical supply before making or changing connections to the unit. ♦ Ensure that the inverter is configured for the correct supply voltage: MICROMASTERS must not be connected to a higher voltage supply. ♦ When synchronous motors are connected or when coupling several motors in parallel, the inverter must be operated with V/f control characteristic (P1300 = 0, 2 or 3). CAUTION After connecting the power and motor cables to the proper terminals, make sure that the front covers have been replaced properly before supplying power to the unit! NOTICE ♦ Ensure that the appropriate circuit-breakers/fuses with the specified current rating are connected between the power supply and inverter (see chapter 5, Tables 5-5). o ♦ Use Class 1 60/75 C copper wire only (for UL compliance). For tightening torque see Table 5-2.

MICROMASTER 440 Operating Instructions 42 6SE6400-5AW00-0BP0 Issue 10/06 2 Installation 2.4.4 Avoiding Electro-Magnetic Interference (EMI) The inverters are designed to operate in an industrial environment where a high level of EMI can be expected. Usually, good installation practices will ensure safe and trouble-free operation. If you encounter problems, follow the guidelines stated below. Action to Take ¾ Ensure that all equipment in the cubicle is well grounded using short, thick grounding cable connected to a common star point or busbar ¾ Make sure that any control equipment (such as a PLC) connected to the inverter is connected to the same ground or star point as the inverter via a short thick link. ¾ Connect the return ground from the motors controlled by the inverters directly to the ground connection (PE) on the associated inverter ¾ Flat conductors are preferred as they have lower impedance at higher frequencies ¾ Terminate the ends of the cable neatly, ensuring that unscreened wires are as short as possible ¾ Separate the control cables from the power cables as much as possible, using separate trunking, if necessary at 90º to each other. ¾ Whenever possible, use screened leads for the connections to the control circuitry ¾ Ensure that the contactors in the cubicle are suppressed, either with R-C suppressors for AC contactors or 'flywheel' diodes for DC contactors fitted to the coils. Varistor suppressors are also effective. This is important when the contactors are controlled from the inverter relay ¾ Use screened or armored cables for the motor connections and ground the screen at both ends using the cable clamps WARNING Safety regulations must not be compromised when installing inverters! MICROMASTER 440 Operating Instructions 6SE6400-5AW00-0BP0 43 2 Installation Issue 10/06 2.4.5 Screening Methods Frame Sizes A, B and C For frame sizes A, B and C the Gland Plate Kit is supplied as an option. It allows easy and efficient connection of the necessary screening. See the Gland Plate Installation Instructions contained on the Document CD-ROM, supplied with the MICROMASTER 440. Screening without a Gland Plate Should a Gland Plate not be available, then the inverter can be screened using the methodology shown in Fig. 2-14. 1 Mains power input 2 Control cable 3 Motor cable 4 Footprint filter 5 Metal back plate 6 Use suitable clips to fix motor and control cable screens securely to metal back plate 7 Screening cables Fig. 2-14 Wiring Guidelines to Minimize the Effects of EMI MICROMASTER 440 Operating Instructions 44 6SE6400-5AW00-0BP0 Issue 10/06 2 Installation Frame Sizes D and E The Gland Plate is factory fitted. If the installation conditions are restricted, the shield of the motor cable can also be attached outside the cabinet, as shown in Fig. 2-14, for example.Frame Sizes FX and GX Frame size F The gland plate for the control cables is factory-fitted. Devices without filter: The shield of the motor cable must be attached outside the cabinet, as shown in Fig. 2-14, for example. Devices with filter: The gland plate for the motor cable is factory-fitted. Frame Sizes FX and GX Connect the wire shields to the shield connection points shown in the connection drawing (see Fig. 2-9 and Fig. 2-10) . Twist the shields of the motor cables and screw them to the PE connection for the motor cable. When using an EMI filter, a power commutating choke is required. The wire shields should be fastened to the metallic mounting surface as close as possible to the components.

MICROMASTER drive inverters operate with high voltages. ¾ When electrical equipment is operated, then specific parts of this equipment are at hazardous voltage levels. ¾ The following terminals can carry dangerous voltages even if the inverter is inoperative: ♦ the power supply L/L1, N/L2, L3 resp. U1/L1, V1/L2, W1/L3 ♦ the motor terminals U, V, W resp. U2, V2, W2 ♦ and depending on the frame size the terminals DC+/B+, DC-, B-, DC/R+ resp. DCPS, DCNS, DCPA, DCNA ¾ Emergency switching-off devices in compliance with EN 60204 IEC 204 (VDE 0113) must remain functional in all operating modes of the control device. When the Emergency switching-off device is reset, then it is not permissible that the equipment runs-up again in an uncontrolled or undefined way. ¾ In cases and situations where short-circuits in the control device can result in significant material damage or even severe bodily injury (i.e. potentially hazardous short-circuits), then additional external measures or devices/equipment must be provided in order to ensure or force operation without any potential hazards, even if a short-circuit occurs (e.g. independent limit switches, mechanical interlocks etc.). ¾ Certain parameter settings can mean that the drive inverter automatically restarts after the power supply voltage fails and then returns. ¾ The motor parameters must be precisely configured in order to ensure perfect motor overload protection. ¾ The drive inverter provides internal motor overload protection according to 2 UL508C, Section 42. I t monitoring is enabled in the default setting (refer to P0610 and P0335). The motor overload protection can also be guaranteed using an external PTC or KTY84. ¾ This equipment is suitable for use in a circuit capable of delivering not more than 10,000 (Frame Sizes A to C) or 42,000 (Frame Sizes D to GX) symmetrical amperes (rms), for a maximum voltage of 230 V / 460 V / 575 V when protected by an H, J or K type fuse, a circuit breaker or self-protected combination motor controller (for more details see Appendix F). ¾ The drive unit may not be used as 'Emergency switching-off device' (refer to EN 60204, 9.2.5.4). CAUTION Only qualified personnel may commission (start-up) the equipment. Safety measures and warnings must be always extremely carefully observed and fulfilled. MICROMASTER 440 Operating Instructions 50 6SE6400-5AW00-0BP0 Issue 10/06 3 Functions 3.1 Parameters 3.1.1 Setting / monitoring parameters and parameter attributes The drive inverter is adapted to the particular application using the appropriate parameters. This means that each parameter is identified by a parameter number , parameter text and specific attributes (e.g. readable, can be written into, BICO attribute, group attribute etc.). Within any one particular drive system, the parameter number is unique. On the other hand, an attribute can be assigned a multiple number of times so that several parameters can have the same attribute. For MICROMASTER, parameters can be accessed using the following operator units: ¾ BOP (option) ¾ AOP (option) ¾ PC-based commissioning (start-up) tool "Drive Monitor" or "STARTER". These PC-based tools are supplied on the CD-ROM. The parameter types are the main differentiating feature of the parameters. Parameter Read (r....) Write/Read (P....) "normal" "normal" BICO output BICO input Read parameters Write-/Read parameters Fig. 3-1 Parameter types Setting parameters Parameters which can be written into and read – "P" parameters These are activated/de-activated in the individual functions or parameters directly influence the behavior of a function. The value of this parameter is saved in a non- volatile memory (EEPROM) as long as the appropriate option was selected (non- volatile data save). Otherwise, these values are saved in the non-volatile memory (RAM) of the processor, which are lost after power failure or power-off/power-on operations.

When transferred to P0013[2] a parameter this means that an indexed parameter can . . . assume several values. The values are addressed via the parameter number including the index value (e.g. P0013[18] P0013[0], P0013[1], P0013[2], P0013[3], P0013[4], ...). P0013[19] Index parameters, for example, are used for: ƒ Drive data sets ƒ Command data sets ƒ Sub-functions In addition to the parameter number and parameter text, every setting and monitoring parameter has different attributes which are used to individually define the properties/characteristics of the parameter. The attributes are listed in the following Table which are used for MICROMASTER. Table 3-1 Parameter attributes Attribute Attribute Description group Data types The data type of a parameter defines the maximum possible value range. 3 data types are used for MICROMASTER. They either represent an unsigned integer value (U16, U32) or a floating-point value (float). The value range is frequently restricted by a minimum, maximum value (min, max) or using drive inverter/motor quantities. U16 Unsigned, integer value with a size of 16 bits, max. value range: 0 .... 65535 U32 Unsigned, integer value with a size of 32 bits max. value range: 0 .... 4294967295 Float A simple precise floating point value according to the IEEE standard format +38 +38 max. value range: -3.39e – +3.39e MICROMASTER 440 Operating Instructions 52 6SE6400-5AW00-0BP0 Issue 10/06 3 Functions Attribute Attribute Description group The value range, which is specified as a result of the data type, is restricted/limited by Value range the minimum, maximum value (min, max) and using drive inverter/motor quantities. Straightforward commissioning (start-up) is guaranteed in so much that the parameters have a default value. These values (min, def, max) are permanently saved in the drive inverter and cannot be changed by the user. - No value entered (e.g.: "r parameter") Min Minimum value Def Default value Max Maximum value Unit For MICROMASTER, the units of a particular parameter involve the physical quantity (e.g. m, s, A). Quantities are measurable properties/characteristics of physical objects, operations, states and are represented using characters of a formula (e.g. V = 9 V). - No dimension % Percentage A Ampere V Volt Ohm Ohm us Microseconds ms Milliseconds s Seconds Hz Hertz kHz Kilohertz 1/min Revolutions per minute [RPM] m/s Meters per second Nm Newton meter W Watt kW Kilowatt Hp Horse power kWh Kilowatt hours °C Degrees Celsius m Meter kg Kilograms ° Degrees (angular degrees) Access level The access level is controlled using parameter P0003. In this case, only those parameters are visible at the BOP or AOP, where the access level is less than or equal to the value assigned in parameter P0003. On the other hand, for DriveMonitor and STARTER, only access levels 0 and 4 are relevant. For example, parameters with access level 4 cannot be changed if the appropriate access level has not been set. The following access levels are implemented in the family of MICROMASTER drive units: 0 User-defined parameter list (refer to P0013) 1 Standard access to the most frequently used parameters 2 Extended access, e.g. to drive inverter I/O functions 3 Expert access only for experienced users 4 Service access only for authorized service/maintenance personnel – with password protection. As far as the ability to visualize the parameters is concerned, the group assignment of the individual parameters must be taken into account. Parameter P0004 is used for the control (refer to the Grouping). MICROMASTER 440 Operating Instructions 6SE6400-5AW00-0BP0 53 3 Functions Issue 10/06 Attribute Attribute Description group The parameters are sub-divided into groups according to their functionality. This Grouping increases the transparency and allows a parameter to be quickly searched for. Furthermore, parameter P0004 can be used to control the ability to be visualized for the BOP / AOP.

The parameter value is not accepted if the instantaneous state is not listed in the parameter attribute "Change state". For instance, the commissioning (start-up) parameter P0010 with the attribute "CT" can only be changed in quick start-up "C" or ready "T" but not in run "U". C Quick commissioning (start-up) U Operation (run) T Ready QC. This parameter attribute identifies as to whether the parameter is included in the quick commissioning (start-up) (P0010 = 1). No The parameter is not included in the quick commissioning (start-up) Yes The parameter is included in the quick commissioning (start-up) Active This attribute is only of importance in conjunction with a BOP. The "Immediate" attribute indicates that this value is already accepted when scrolling (when changing the value with or ). Especially parameters which are used for optimization functions have this property (e.g. constant voltage boost P1310 or filter time constants). On the other hand, for parameters with the attribute "After actuation", the value is only accepted after first actuating the key . These include, for example, parameters where the parameter value can have different settings/meanings (e.g. selecting the frequency setpoint source P1000). Immediately The value becomes valid by either scrolling with or After The value is only accepted by pressing actuation MICROMASTER 440 Operating Instructions 54 6SE6400-5AW00-0BP0 Issue 10/06 3 Functions The attributes and groups are shown, in the parameter list, in the header line of the parameter.

This interconnection functionality must have a high degree of flexibility in order to be able to adapt the drive to new applications. Further, a high degree of usability is required, which also fulfills standard applications. This is the reason that within the MICROMASTER series of drive units, BICO technology (→ flexibility) and fast parameterization using parameters P0700 / P1000 (→ usability) or P0719 (→ combination P0700/P1000) have been introduced to be able to fulfill both of these requirements. 3.1.2.1 Selecting the command source P0700 / selecting the setpoint source P1000 The following parameters can be used to quickly interconnect setpoints and control signals: ¾ P0700 "Selection of command source" ¾ P1000 "Selection of setpoint source" These parameters are used to define via which interface the drive inverter receives the setpoint or the power-on/power-off command. The interfaces, listed in Table 3-2 can be selected for the command source P0700. Table 3-2 Parameter P0700 Parameter values Significance / command source 0 Factory default BOP (operator panel, refer to Section 3.2.1) 1 Terminal strip 2 4 USS on BOP link USS on COM link 5 CB on COM link 6 The following internal or external sources / interfaces can be selected for the st frequency setpoint source P1000. In addition to the main setpoint (1 position), a nd supplementary setpoint (2 position) can be selected (refer to Table 3-3).

The AOP can be connected to both the BOP link (RS 232) as well as at the COM link interface (RS 485) of the drive inverter. If the AOP is to be used as command source or setpoint source then for parameter P0700 or P1000, either "USS on BOP link" or "USS on COM link" should be selected. ¾ The complete list of all of the setting possibilities can be taken from the parameter list (refer to parameter list P1000). ¾ Parameters P0700 and P1000 have the following default settings: a) P0700 = 2 (terminal strip) b) P1000 = 2 (analog setpoint) In this case, the selection of the command source is made independently of the selection of the frequency setpoint source. This means that the source to enter the setpoint does not have to match the source to enter the power-on/power-off com- mand (command source). This means, for example, that the setpoint (P1000 = 4) can be connected via an external device which is connected to the BOP link interface via USS and the control (ON/OFF command, etc.) is entered via digital inputs (terminals, P0700 = 2). CAUTION ¾ When P0700 or P1000 are modified, then the frequency inverter also changes the subordinate BICO parameters (refer to the parameter list for P0700 or P1000 in the appropriate tables) ¾ There is no prioritization (priority assignment) between direct BICO parameterization and P0700/P1000. The last modification is valid. MICROMASTER 440 Operating Instructions 58 6SE6400-5AW00-0BP0 Issue 10/06 3 Functions 3.1.2.2 Selection of command/frequency setpoint P0719 Parameter P0719 represents a combination of the functionalities of the two parameters P0700 and P1000. Here, it is possible to changeover the command source as well as also the frequency setpoint source via a parameter change. Contrary to P0700 and P1000, for parameter P0719, the subordinate (lower-level) BICO parameters are not changed. This characteristic/feature is especially used by PC tools in order to briefly retrieve the control authority for the drive without having to change the existing BICO parameterization. Parameter P0719 "Selection of command/frequency setpoint" comprises the command source (Cmd) and the frequency setpoint (setpoint).

This characteristic/feature can be used during service if the control authority must be briefly and quickly re-assigned (e.g. selecting and executing the motor data identification routine using a PC-based tool). MICROMASTER 440 Operating Instructions 6SE6400-5AW00-0BP0 59 3 Functions Issue 10/06 3.1.2.3 BICO technology Using BICO technology (English: Binector Connector Technology), process data can be freely interconnected using the "standard" drive parameterization. In this case, all values which can be freely interconnected (e.g. frequency setpoint, frequency actual value, current actual value, etc.) can be defined as "Connectors" and all digital signals which can be freely interconnected (e.g. status of a digital input, ON/OFF, message function when a limit is violated etc.) can be defined as "Binectors". There are many input and output quantities as well as quantities within the closed- loop control which can be interconnected in a drive unit. It is possible to adapt the drive to the various requirements using BICO technology. A binector is a digital (binary) signal without any units and which can either have the value 0 or 1. Binectors always refer to functions whereby they are sub-divided into binector inputs and binector outputs (refer to Fig. 3-4). In this case, the binector input is always designated using a "P" parameter with attribute "BI" (e.g.: P0731 BI: Function, digital output 1), while the binector output is always represented using an "r" parameter with attribute "BO" (e.g.: r0751 BO: ADC status word). As can be seen from the examples above, the binector parameters have the following abbreviations in front of the parameter names: ¾ BI Binector Input, signal receiver ("P" parameters) → The BI parameter can be interconnected with a binector output as source, by entering the parameter number of the binector output (BO parameter) as value in the BI parameter (e.g.: Interconnecting the "BO" parameter r0751 with "BI" parameter P0731 → P0731 = 751). ¾ BO Binector Output, signal source ("r" parameters) → The BO parameter can be used as source for BI parameters. For the particular interconnection the BO parameter number must be entered into the BI parameter (e.g.: Interconnecting the "BO" parameter r0751 with "BI" parameter P0731 → P0731 = 751). Abbreviation and symbol Name Function Binector input BI Data flow (signal receiver) Pxxxx Function BI: ... Binector output BO Data flow (signal source) rxxxx Function BO: ... Fig. 3-4 Binectors A connector is a value (16 or 32 bit), which can include a normalized quantity (without dimension) as well as also a quantity with associated units. Connectors always refer to functions whereby they are sub-divided into connector inputs and connector outputs (refer to Fig. 3-5). Essentially the same as the binectors, the connector inputs are characterized by a "P" parameter with attribute "CI" (e.g.: P0771 CI: D/A converter); while the connector outputs are always represented using an "r" parameter with attribute "CO" (e.g.: r0021 CO: Smoothed output frequency). MICROMASTER 440 Operating Instructions 60 6SE6400-5AW00-0BP0 Issue 10/06 3 Functions As can be seen from the examples above, connector parameters have the following abbreviations in front of the parameter names: ¾ CI Connector Input, signal sink ("P" parameters) → The CI parameter can be interconnected with a connector output as source, by entering the parameter number of the connector output (CO parameter) as value in the CI parameter (e.g.: P0771 = 21). ¾ CO Connector Output, signal source ("r" parameters) → The CO parameter can be used as source for CI parameters. For the particular interconnection, the CO parameter number must be entered in the CI parameter (e.g.: P0771 = 21). Further, MICROMASTER has "r" parameters where several binector outputs are combined in a word (e.g.: r0052 CO/BO: Status word 1). This feature reduces, on one hand, the number of parameters and simplifies parameterization via the serial interface (data transfer). This parameter is further characterized by the fact that it does not have any units and each bit represents a digital (binary) signal. As can be seen from the examples of parameters, these combined parameters have the following abbreviation in front of the parameter names: ¾ CO/BO Connector Output / Binector Output, signal source ("r" parameters) → CO/BO parameters can be used as source for CI parameters and BI parameters: a) In order to interconnect all of the CO/BO parameters, the parameter number must be entered into the appropriate CI parameter (e.g.: P2016[0] = 52). b) When interconnecting a single digital signal, in addition to the CO/BO parameter number, the bit number must also be entered into the BI parameter (e.g.: P0731 = 52.3) Abbreviation and symbol Name Function Connector input CI Data flow (signal receiver) Pxxxx Function CI: ...

Fig. 3-5 Connectors In order to interconnect two signals, a BICO setting parameter (signal receiver) must be assigned the required BICO monitoring parameter (signal source). A typical BICO interconnection is shown using the following examples (refer to Fig. 3-6).

MICROMASTER 440 Operating Instructions 62 6SE6400-5AW00-0BP0 Issue 10/06 3 Functions 3.1.3 Data sets For many applications it is advantageous if several parameters can be simultaneously changed, during operation or in the ready state, using an external signal. Examples: ¾ The drive inverter should be switched-over from motor 1 to motor 2. Motor 1 M1 MM4 Motor 2 M2 Fig. 3-7 Example: Changeover from motor 1 to motor 2 ¾ The control source (e.g. terminal → BOP) or setpoint (frequency) source (e.g. ADC → MOP) should be changed-over using a terminal signal (e.g. DIN4) as function of an external event (e.g. the higher-level control unit fails). A typical example in this case is a mixer, which may not come to an uncontrolled stop when the control fails. Control source: Terminal → BOP Setpoint (frequency source): ADC → MOP P0810 = 722.3 DIN4 P0700[0] = 2 0 Terminals Sequence control 1 P0700[1] = 1 BOP P1000[0] = 2 0 ADC Setpoint Motor channel control 1 P1000[1] = 1 MOP Fig. 3-8 Example: Changing-over between the control and setpoint (frequency) source This functionality can be elegantly implemented using indexed parameters (refer to Section 3.1.1). In this case, as far as the functionality is concerned, the parameters are combined to form groups / data sets and are indexed. By using indexing, several different settings can be saved for each parameter which can be activated by changing-over the data set (i.e. toggling between data sets). The following data sets apply: CDS Command Data Set DDS Drive Data Set MICROMASTER 440 Operating Instructions 6SE6400-5AW00-0BP0 63 K2 K1 3 Functions Issue 10/06 3 independent settings are possible for each data set. These settings can be made using the index of the particular parameter: CDS1 ... CDS3 DDS1 ... DDS3 Those parameters (connector and binector inputs) which are used to control the drive and enter a setpoint, are assigned to the command data set (CDS). The signal sources for the control commands and setpoints are interconnected using BICO technology (refer to Section 3.1.2.3). In this case, the connector and binector inputs are assigned as signal sources corresponding to the connector and binector outputs. A command data set includes: ¾ Command sources and binector inputs for control commands (digital signals) e.g.: ♦ Selects the command source P0700 ♦ ON/OFF1 P0840 ♦ OFF2 P0844 ♦ Enable JOG right P1055 ♦ Enable JOG left P1056 ¾ Setpoint sources and connector inputs for setpoints (analog signals) e.g.: ♦ Selection of frequency setpoint P1000 ♦ Selection of main setpoint P1070 ♦ Selection of additional setpoint P1075 The parameters, combined in a command data set, are designated with [x] in the parameter list in the index field. Index: st Pxxxx[0] : 1 command data set (CDS) nd Pxxxx[1] : 2 command data set (CDS) rd Pxxxx[2] : 3 command data set (CDS) NOTE A complete list of all of the CDS parameters can be taken from the parameter list. It is possible to parameterize up to three command data sets. This makes it easier to toggle between various pre-configured signal sources by selecting the appropriate command data set. A frequent application involves, for example, the ability to toggle between automatic and manual operation. MICROMASTER has an integrated copy function which is used to transfer command data sets. This can be used to copy CDS parameters corresponding to the particular application. The copy operation is controlled with P0809 as follows (refer to Fig. 3-9): 1. P0809[0] = Number of the command data set which is to be copied (source) 2. P0809[1] = Number of the command data set into which data is to be copied (target) 3. P0809[2] = 1 → Copying is started Copying has been completed, if P0809[2] = 0. MICROMASTER 440 Operating Instructions 64 6SE6400-5AW00-0BP0 Issue 10/06 3 Functions P0809[0] = 0 1. CDS P0809[1] = 2 3.

It is possible to parameterize several drive data sets. This makes it easier to toggle between various drive configurations (control mode, control data, motors) by selecting the appropriate drive data set.

P0819[0] = Number of the drive data set which is to be copied (source) 2. P0819[1] = Number of the drive data set into which data is to be copied (target) 3.

This conversion is undertaken by the particular interface using the reference quantities. The normalization / de- normalization is carried-out for the following interfaces: Table 3-5 Normalized interfaces Interafce 100 % Analog input Current input 20 mA Voltage input 10 V Analog output Current output 20 mA Voltage output 10 V USS 4000 h CB 4000 h Further, for a BICO connection, a normalization is carried-out if the connector output (CO) represents a physical quantity and the connector input (CI) a normalized (percentage) quantity (e.g. PID controller). De-normalization is carried- out if the inverse situation exists. This normalization / de-normalization should be carefully taken into consideration, especially for the free function blocks (FFBs). Reference quantities (normalization quantities) are intended to allow setpoint and actual value signals to be represented in a standard fashion (normalization / de- normalization of physical quantities such as setpoint and actual frequency). This also applies for permanently set parameters that are entered as a "percentage". A value of 100 % corresponds to a process data value PZD of 4000 h (USS or CB) – or a current / voltage value of 20 mA / 10 V (analog input / output). The following reference parameters and permanently saved reference values are available: Table 3-6 Normalization functions Parameter Designation Value (100 % / 4000 h) Units P2000 Reference frequency P2000 Hz P2001 Reference voltage P2001 V P2002 Reference current P2002 A P2003 Reference torque P2003 Nm r2004 Reference power π P2000 P2003 kW * * - Reference speed P2000 60 / r0313 RPM * - Reference temperature 100 °C °C - Reference energy 100 kWh kWh MICROMASTER 440 Operating Instructions 68 6SE6400-5AW00-0BP0 Issue 10/06 3 Functions Example Using the reference frequency P2000 as example, normalization / de-normalization is demonstrated via the serial interface "USS at BOP link". If the connection between two BICO parameters is closed (directly using the BICO parameters or indirectly using P0719 or P1000), that have different representation types (normalized representation (hex) or physical representation (Hz)), then in the frequency inverter, the following normalization is made to the target value: P2016 r0021 [0] r0021[Hz] USS-PZD [1] y[Hex] = ⋅ 4000[Hex] BOP link P2000[Hz] [2] [3] x[Hz] y[Hex] r2015 [0] P1070 r2015[1] USS-PZD [1] y[Hz] = ⋅P2000 BOP link 4000[Hex] [2] [3] x[Hex] y[Hz] Fig. 3-13 Normalization / de-normalization Note ¾ Analog values are limited to 10 V or 20 mA. A maximum of 100 % referred to the corresponding reference values can be output / entered as long as no DAC/ADC scaling is made (factory setting). ¾ Setpoints and actual value signals via serial interface: ♦ When transferring using the PZD part, they are limited to the value 7FFF h. This is the reason that the maximum value is 200 % referred to the reference value. ♦ When transferring data using the PKW part, they are transferred dependant on the data type and the units. ¾ Parameter P1082 (max. frequency) limits the frequency in the frequency inverter independent of the reference frequency. When changing P1082 (factory setting: 50 Hz), this is the reason that P2000 should always be adapted (factory setting: 50 Hz). If, e.g. for a NEMA motor, the parameter is set to 60 Hz, and no changes are made regarding P2000, then the analog setpoint / actual value is limited to 100 % or a setpoint / actual value signal at 4000 h is limited to 50 Hz! MICROMASTER 440 Operating Instructions 6SE6400-5AW00-0BP0 69 3 Functions Issue 10/06 3.2 Operator panels for MICROMASTER MICROMASTER drive units can be optionally equipped with a BOP (Basic Operator Panel) or AOP (Advanced Operator Panel). The AOP distinguishes itself as a result of a plain text display which simplifies operator control, diagnostics as well as also commissioning (start-up). BOP AOP Fig. 3-14 Operator panels 3.2.1 Description of the BOP (Basic Operator Panel) The BOP, available as option, allows drive inverter parameters to be accessed. In this case, the Status Display Panel (SDP) must be removed and the BOP either inserted or connected in the door of a cabinet using a special mounting kit (Operator panel door mounting set) (refer to the Attachment A). Parameter values can be changed using the BOP. This allows the MICROMASTER drive unit to be set-up for a particular application. In addition to the keys (refer to Section 3.2.3), it includes a 5-digit LCD display on which the parameter numbers rxxxx and Pxxxx, parameter values, parameter units (e.g. [A], [V], [Hz], [s]), alarm Axxxx or fault messages Fxxxx as well as setpoints and actual values. NOTE ¾ Contrary to the AOP, for the BOP, parameters do not have to be set or taken into consideration when establishing the communications between the BOP and drive inverter. ¾ A BOP does not have a local memory. This means that it is not possible to save a parameter set on the BOP. MICROMASTER 440 Operating Instructions 70 6SE6400-5AW00-0BP0 Issue 10/06 3 Functions 3.2.2 Description of the AOP (Advanced Operator Panel) An AOP (this is available as option) has the following additional functions with respect to a BOP: ¾ Multi-language and multi-line plain text display ¾ Units are additionally displayed, such as [Nm], [°C], etc. ¾ Active parameters, fault messages, etc. are explained ¾ Diagnostics menu to support troubleshooting ¾ The main menu is directly called by simultaneously pressing keys Fn and P ¾ Timer with 3 switching operations per entry ¾ Up to 10 parameter sets can be downloaded / saved ¾ Communications between an AOP and MICROMASTER are realized using the USS protocol. An AOP can be connected to the BOP link (RS 232) as well as to the COM link interface (RS 485) of the drive inverter. ¾ Multi-point capable coupling to control (open-loop) and visualize up to 31 MICROMASTER drive inverters. The USS bus must, in this case, be configured and parameterized via the drive inverter terminals of the COM link interface. Please refer to Sections 3.2.3, 3.2.4 and the AOP Manual for additional details. NOTE ¾ Contrary to the BOP, for the AOP, the communications parameters of the particular interface must be taken into account. ¾ When inserting / connecting to the drive inverter, the AOP automatically changes the parameter P2012 (USS-PZD length) to 4 corresponding to the interface. COM link: P2012[0] BOP link: P2012[1] ¾ For DriveMonitor, the default value for the USS-PZD length is set to 2. This results in a conflict if the AOP and the DriveMonitor are operated, alternating, at the same interface. Remedy: Increase the USS-PZD length to 4.

The actual application should only be commissioned if the drive inverter – motor combination provides a satisfactory result. If the drive is to be commissioned from a defined state, then the drive inverter can be reset to the initial state when it left the plant. This is done as follows: ¾ Reset parameters to the factory setting Check list The following check list should help you to commission MICROMASTER without any problems and to guarantee a high degree of availability: ¾ When handling the drive unit, carefully observe all of the ESD measures. ¾ All of the screws must have been tightened up to their specified torque. ¾ All connectors / option modules must have been correctly inserted and locked / screwed into place. ¾ The DC link pre-charging has been completed. ¾ All of the components are grounded/earthed at the points provided and all of the shields have been connected. ¾ MICROMASTER drive units have been designed for defined mechanical, climatic and electrical ambient conditions. It is not permissible that the specified limit values are exceeded in operation and when the drive units are being transported. The following must be especially carefully observed: ♦ Line supply conditions ♦ Pollutant stressing ♦ Gases which can have a negative impact on the function ♦ Ambient climatic conditions ♦ Storage / transport ♦ Shock stressing ♦ Vibration stressing ♦ Ambient temperature ♦ Installation altitude In addition to carrying-out all of the installation work, an important prerequisite for successful commissioning is that the drive inverter is not disconnected from the line supply while being parameterized. If a line supply failure interrupts commissioning, then inconsistencies can occur regarding the parameterization. In this case, it is important that the commissioning is re-started (possibly reset and establish the original factory settings (refer to Section 3.5.9)). NOTE When using output reactors, the pulse frequency may not be set higher than 4 kHz. The following parameter setting is mandatory when using an output reactor: P1800 = 4 kHz , P0290 = 0 or 1 MICROMASTER 440 Operating Instructions 78 6SE6400-5AW00-0BP0 Issue 10/06 3 Functions 3.5.1 50/60 Hz setting The frequency setting made in the factory can be adapted to the North American market, without requiring any parameterization using an operator panel or PC tool using the DIP50/60 switch (refer to Fig. 3-21) under the I/O board (refer to the Appendix C when removing the I/O board). DIP50/60 Fig. 3-21 DIP switch to change-over between 50/60 Hz The switch determines the value of parameter P0100 corresponding to the following diagram (refer to Fig. 3-22). Besides P0100 = 2, after the power supply voltage has been switched-in, the DIP50/60 switch determines the 50/60 Hz setting (value of parameter P0100). Quick Power commissioning cycle P0010 = 1 yes yes P0100 = 2 P0100 = 2 ? ? no no no P0100 = 1 ? yes no DIP2 = OFF ? yes Power in kW Power in kW Power in hp Frequency 50 Hz Frequency 60 Hz Frequency 60 Hz P0100 = 0 P0100 = 2 P0100 = 1 Fig. 3-22 Mode of operation of the DIP50/60 switch in conjunction with P0100 MICROMASTER 440 Operating Instructions 6SE6400-5AW00-0BP0 79 Remove I/O board 3 Functions Issue 10/06 By changing the setting of DIP50/60 switch, after the drive inverter has been powered-down/powered-up, the parameters for the rated motor frequency P0310, max. frequency P1082 and reference frequency P2000 are automatically pre-set. In addition, the rated motor parameters as well as all of the other parameters which depend on the rated motor parameters, are reset. The units of the power parameters are, depending on P0100, are either interpreted as kW value or hp value. NOTE Switch DIP2(1) (refer to Fig. 3-21) under the I/O board has no function. 3.5.2 Motor circuit In order to ensure a straightforward, successful commissioning, it is important that the circuit connection in the motor terminal box (refer to Fig. 3-23) matches the rated motor voltage entered in P0304 or the rated motor current P0305.

MICROMASTER 440 Operating Instructions 6SE6400-5AW00-0BP0 81 3 Functions Issue 10/06 87 Hz characteristic When a motor with a delta circuit configuration (e. g. V = 230 V) is fed from a N∆, motor frequency inverter, where the rated voltage corresponds to the star circuit configuration (e.g. 400 V frequency inverter), then it is important to proceed as follows and observe the following: ¾ The motor must have the appropriate voltage strength. ¾ Above the rated motor frequency, the iron losses in the motor increase over- proportionally. This is the reason that above this frequency, the thermal motor torque should be reduced. ¾ For the quick commissioning, the rating plate data for the delta circuit configuration should be entered or the rating plate must be appropriately converted. ¾ The drive inverter must be designed for the higher current (delta circuit configuration). ¾ The 87 Hz characteristic is independent of the control type and can therefore be used both for V/f control as well as for closed-loop vector control. ¾ When using the 87 Hz characteristic, the mechanical motor limits must be taken into account (refer to Catalog M11). For the 87 Hz characteristic, the ratio between the voltage and frequency (V/f characteristic) remain constant. This is the reason that the following relationships apply: U U N1 = ⋅ P P N1 N∆ P = power U N∆ U N1 f = frequency (400 V) U N1 n = speed = ⋅ f f N1 N∆ U N∆ U N∆ p = pole pair No. (230 V) ⎡ s ⎤ 60 ⎢ ⎥ min ⎣ ⎦ = () − + nN1 fN1 fN∆ n∆ p f f (50 Hz) f (87 Hz) N1 N∆ Fig. 3-25 V/f characteristic Table 3-8 Example 1LA7060-4AB10 Delta circuit 87 Hz Star circuit configuration characteristic configuration P0304 Rated motor voltage 230 V 400 V 400 V P0305 Rated motor current 0.73 A 0.73 A 0.42 A P0307 Rated motor power 120 W 207 W 120 W P0308 0.75 0.75 0.75 Cos ϕ P0310 Rated motor frequency 50 Hz 87 Hz 50 Hz P0311 Rated motor speed 1350 RPM 2460 RPM 1350 RPM P0314 Motor pole pairs 2 2 2 Contrary to the BOP, AOP operator panels or the commissioning program Drive- Monitor, the STARTER commissioning (start-up) program offers a mask-orientated quick commissioning, which is especially advantageous for users who are using MICROMASTER for the first time. On the other hand, BOP, AOP and DriveMonitor offer, in conjunction with the drive inverter, parameter-orientated quick commissio- ning where the user is navigated through the menu tree mentioned. MICROMASTER 440 Operating Instructions 82 6SE6400-5AW00-0BP0 Issue 10/06 3 Functions 3.5.3 Quick commissioning If there is still no appropriate parameter set for the drive, then a quick commissioning must be carried-out for the closed-loop Vector control and for the V/f control including a motor data identification routine. The following operator units can be used to carry-out quick commissioning: ¾ BOP (option) ¾ AOP (option) ¾ PC Tools (with commissioning program STARTER, DriveMonitor) When the quick commissioning is carried-out, the motor – drive inverter is basically commissioned; the following data must be obtained before quick commissioning is started: ¾ Line supply frequency ¾ Motor rating plate data ¾ Command / setpoint sources ¾ Min. / max. frequency or ramp-up / ramp-down time ¾ Closed-loop control mode ¾ Motor data identification Parameterizing the drive with BOP or AOP The frequency inverter is adapted to the motor using the quick commissioning function and important technological parameters are set. The quick commissioning shouldn't be carried-out if the rated motor data saved in the frequency inverter (4-pole 1LA Siemens motor, star circuit configuration frequency inverter (FU)- specific) match the rating plate data. Parameters, designated with a * offer more setting possibilities than are actually listed here. Refer to the parameter list for additional setting possibilities. NOTE ¾ Parameter P0308 or P0309 can only be viewed on the BOP or AOP if P0003 ≥ 2.

MICROMASTER 440 Operating Instructions 6SE6400-5AW00-0BP0 87 3 Functions Issue 10/06 WARNING The motor data identification routine (refer to Section 0) may not be used for loads which are potentially hazardous (e.g. suspended loads for crane applications). Before the motor data identification run is started, the potentially hazardous load must be carefully secured (e.g. by lowering the load to the floor or by clamping the load using the motor holding brake). 3.5.4 Calculating the motor / control data The calculation of the internal motor / control data is initiated using parameter P0340 or indirectly using parameter P3900 (refer to Section 3.5.3) or P1910 (refer to Section 0). The functionality of parameter P0340 can, for example, be used if the equivalent circuit diagram data (refer to Fig. 3-26) or the moment of inertia is known. Possible settings for parameter P0340 are described in Table 3-9. Table 3-10 lists which parameters are calculated for the different settings. Table 3-9 Possible settings for parameter P0340 Parameter Description P0340 = 0 No calculation is made P0340 = 1 Starting from the rating plate parameters (P0300 - P0335) the motor equivalent circuit diagram parameters (P0350 - P0369) and the motor weight / moment of inertia (P0344, P0341) are determined. The V/f- / vector control parameters and reference quantities are then pre-assigned (this includes all calculations from P0340 = 2,3,4). P0340 = 2 Starting from the rating plate parameters, the motor equivalent circuit diagram parameters (P0350 - P0369) are calculated (without any additional pre-assignments being made). P0340 = 3 Starting from the motor equivalent circuit diagram parameters (P0350 - P0369) and motor weight / moment of inertia, moment of inertia ratio (P0344, P0341, P0342), the V/f- / vector control parameters are determined (contains all of the calculations from P0340 = 4). P0340 = 4 Starting from the motor equivalent circuit diagram parameters (P0350 - P0369) and motor weight / moment of inertia, moment of inertia ratio (P0344, P0341, P0342), the vector control parameters are pre-assigned. NOTE ¾ When exiting the quick commissioning with P3900 > 0 (refer to Section 3.5.3), internally P0340 is set to 1 (complete parameterization). ¾ For the motor data identification (refer to Section 0), after the measurement has been completed, internally P0340 is set to 3. ¾ Equivalent circuit diagram data always refer to the star circuit configuration equivalent circuit diagram. If data for the delta equivalent circuit diagram are available, then this should first be converted into the star equivalent circuit diagram data before being entered. ¾ If equivalent circuit diagram data (P0350, . . ., P0360) is available, then this must be entered according to the motor circuit configuration being used (a star circuit configuration requires star-type equivalent circuit diagram data). If there is no consistency between the motor circuit configuration and the equivalent circuit diagram data, then the equivalent circuit diagram data should be converted according to the motor circuit configuration actually being used (P0350 = P0350 , etc.). ∆ Y MICROMASTER 440 Operating Instructions 88 6SE6400-5AW00-0BP0 Issue 10/06 3 Functions Table 3-10 Calculated parameters P0340 = 1 P0340 = 2 P0340 = 3 P0340 = 4 x P0341[3] Motor inertia [kg*m^2] P0342[3] Total/motor inertia ratio x P0344[3] Motor weight x x x P0346[3] Magnetization time P0347[3] Demagnetization time x x P0350[3] Stator resistance (line-to-line) x x x x P0352[3] Cable resistance x x P0354[3] Rotor resistance P0356[3] Stator leakage inductance x x x x P0358[3] Rotor leakage inductance x x P0360[3] Main inductance P0362[3] Magnetizing curve flux 1 x x x x P0363[3] Magnetizing curve flux 2 x x P0364[3] Magnetizing curve flux 3 P0365[3] Magnetizing curve flux 4 x x x x P0366[3] Magnetizing curve imag 1 x x P0367[3] Magnetizing curve imag 2 P0368[3] Magnetizing curve imag 3 x x x x P0369[3] Magnetizing curve imag 4 x x P0625[3] Ambient motor temperature P1253[3] Vdc-controller output limitation x x x x P1316[3] Boost end frequency x x x P1460[3] Gain speed controller P1462[3] Integral time speed controller x x x P1470[3] Gain speed controller (SLVC) x x x x x x P1472[3] Integral time n-ctrl.

MICROMASTER 440 Operating Instructions 90 6SE6400-5AW00-0BP0 Issue 10/06 3 Functions 3.5.5 Motor data identification MICROMASTER has a measuring technique which is used to determine the motor parameters: ¾ Equivalent circuit data (ECD, refer to Fig. 3-26) → P1910 = 1 ¾ Magnetizing characteristic (refer to Fig. 3-27) → P1910 = 3 For control-related reasons, we absolutely recommend that the motor data identification is carried-out as, starting from the rating plate data, it is only possible to estimate the equivalent circuit data, the motor cable resistance, the IGBT let- through voltage and the compensation of IGBT interlocking times. For example, the stator resistance is extremely important for the stability of the closed-loop Vector control and for the voltage boost for the V/f characteristic. The motor data identification routine should be executed, especially if long feeder cables or if third- party motors are being used. If the motor data identification routine is being started for the first time, then the following data (refer to Fig. 3-26) is determined, starting from the rating plate data (rated [nominal] data) with P1910 = 1: ¾ Equivalent circuit data ¾ Motor cable resistance ¾ IGBT on-state voltage and compensation of IGBT gating dead times The rating plate data represent the initialization values for the identification. This is the reason that it is necessary to have correct and consistent input of the rating plate data when determining the data specified above (refer to Section 3.5.8). Stator res.

If the motor-drive inverter combination is operated in the field-weakening range, then this characteristic should be determined, especially when Vector control is being used. As a result of this magnetizing characteristic, MICROMASTER can, in the field-weakening range, more precisely calculate the current which is generating the field and in turn achieve a higher torque accuracy.

The motor identification routine is started by the ON command and different excitation signals are impressed in the motor (DC and AC voltages). This measurement is carried-out with the motor at a standstill and it takes, including the data calculation per selection (P1910 = 1.3) between 20 s ... 4 min. The identification time depends on the motor and increases with its size (this takes approx. 4 min for a 200 kW motor). The motor data identification routine must be carried-out with the motor in the cold condition so that the motor resistance values saved can be assigned to the parameter of the ambient temperature P0625. Only then is correct temperature adaptation of the resistances possible during operation. The motor data identification routine operates with the results of the "Complete parameterization" P0340 = 1 or the motor equivalent diagram data which was last saved. The results become increasingly better the more times that the identification routine is executed (up to 3 times). WARNING ¾ It is not permissible to carry-out the motor identification routine for loads which are potentially hazardous (e.g. suspended loads for crane applications). Before starting the motor data identification routine, the potentially hazardous load must be secured (e.g. by lowering the load to the floor or clamping the load using the motor holding brake). ¾ When starting the motor data identification routine, the rotor can move into a preferred position. This is more significant for larger motors. MICROMASTER 440 Operating Instructions 92 6SE6400-5AW00-0BP0 Issue 10/06 3 Functions NOTE ¾ The equivalent circuit data (P0350, P0354, P0356, P0358, P0360), with the exception of parameter P0350, should be entered as phase values. In this case, parameter P0350 (line-to-line value) corresponds to twice the phase value. ¾ Equivalent circuit diagram data always refer to the star circuit configuration equivalent circuit diagram data. If data for the delta equivalent circuit diagram is available, then this data must be converted into the star equivalent circuit diagram data before being entered (refer to Section 0). ¾ The motor cable resistance P0352 is defined as phase value ¾ During the motor identification routine, the stator resistance and the motor cable resistance are determined and entered into parameter P0350. If a correction is made in parameter P0352, then MICROMASTER defines the motor cable resistance using the following relationship: P0352 = 0.2 * P0350. ¾ If the motor cable resistance is known, then the value can be entered into parameter P0352 after the motor data identification. The stator resistance is appropriately reduced as a result of this entry and is therefore more precisely adapted to the actual application. ¾ It is not necessary to lock the motor rotor for the motor data identification routine. However, if it is possible to lock the motor rotor during the identification routine (e.g. by closing the motor holding brake), then this should be used to determine the equivalent circuit diagram data. ¾ The following formula can be applied to check the correctness of the motor rating plate data: P = √3 ∗ V ∗ I ∗ cosϕ ∗ η ≈ √3 ∗ V ∗ I ∗ cosϕ ∗ η N N Υ NΥ N ∆ N∆ with P rated motor power N V , V rated motor voltage (star / delta) N Υ N ∆ I , I rated motor current (star / delta) N Υ N ∆ cosϕ power factor η efficiency Motor data identification routine START Factory setting 20 °C P0625 = ?

If this is ≤ 5 °C ? not the case, then the motor data identification routine can only be carried-out after the motor has cooled down. yes no Allow the motor to cool down MICROMASTER 440 Operating Instructions 6SE6400-5AW00-0BP0 93 3 Functions Issue 10/06 0 P1910 = 1 Select motor data identification with P1910 = 1 p1910 = 1: Identifies the motor parameter with parameter change.

ON Starts the motor data identification run with p1910 = 1 The measuring operation is initiated with the continuous (steady-state) ON command. The motor aligns itself and current flows through it. Diagnostics is possible using r0069 (CO: Phase current). After the motor data identification routine has been completed, p1910 is reset (p1910 = 0, motor data identification routine inhibited) and Alarm A0541 is cleared (deleted). OFF1 In order to set the frequency converter into a defined state, an OFF1 command must be issued before the next step. 0 Select motor data identification with P1910 = 3 P1910 = 3 p1910 = 3: Identifies the saturation characteristic with parameter change.

OFF1 In order to set the frequency converter into a defined state, an OFF1 command must be issued before the next step. END If problems occur during the identification run, e.g. the current controller oscillates, then the rating plate data should be re-checked and an approximately correct magnetizing current P0320 entered. The motor data identification routine should then be re-started by calling P0340 = 1 (refer to Section 3.5.4). MICROMASTER 440 Operating Instructions 94 6SE6400-5AW00-0BP0 Issue 10/06 3 Functions 3.5.6 Magnetizing current ¾ The value of the magnetizing current r0331/P0320 has a significant influence on the closed-loop control. This cannot be measured at standstill. This means that the value is estimated for standard 4-pole 1LA7 SIEMENS standard using the automatic parameterization P0340=1 (P0320=0; result in r0331). ¾ If the deviation of the magnetizing current is too high, then the values for the magnetizing reactance and those of the rotor resistance will not be able to be accurately determined. ¾ Especially for third-party motors it is important that the magnetizing current that is determined, is carefully checked and if required, appropriately corrected. The procedure to manually determine the magnetizing current and to re-calculate the equivalent circuit diagram data when the drive is operated with closed-loop vector control (P1300 = 20/21) is shown in the following. MICROMASTER 440 Operating Instructions 6SE6400-5AW00-0BP0 95 3 Functions Issue 10/06 START Quick Quick commissioning routine commissioning Using the quick commissioning routine the frequency inverter is adapted to the motor and important technology parameters are set. Motor data Motor data identification routine identificationdentif Using the motor data identification routine motor equivalent circuit diagram data is determined using a measuring technique. Operation under Determing the magnetizing current no-load conditions In order to determine the magnetizing current (P0320/r0331), the motor should be accelerated up to approximately 80% of its rated speed under no-load operating conditions. In so doing, the following conditions must be carefully maintained: − the vector control must be activated, P1300 = 20.21 − no field weakening (r0056.8 = 0) − flux setpoint, r1598 = 100 % − no efficiency optimization, P1580 = 0 % No-load operation means that the motor is operated without a load (i.e. no coupled driven machine). Under steady-state conditions, a current r0027 is obtained that approximately corresponds to the rated magnetizing current r0331. (the current is always less than the no-load current for a pure V/f control). Measuring and entering the magnetizing current and therefore the associated Criterium new calculation of the equivalent circuit diagram data of the motor is an fulfilled ? iterative procedure. It must be repeated at least 2-3 times until the following criteria are fulfilled: no yes − The more accurate the value of the magnetizing current that was entered, the better the flux setpoint (r1598=100%) matches the flux actual value (r0084=96..104%) of the observer model. − The output Xm adaptation (r1787) of the observer model should be as low as possible. Good values lie between 1-5%. The less that the Xh adaptation of the observer must operate, the sensitivity of the motor parameters after power failures are that much less sensitive. NOTE In order to display r0084 at the BOP/AOP, the LEVEL 4 parameters must be enabled using service parameter P3950=46. 0 P0320 = ... Calculating P0320 Now, the new value can be entered in P0320 from the determined flux- generating current component r0029 by applying the following equation. P0320 = r0029 * 100 / P0305 0 P0340 = 1 Calculating the motor parameters The values of the motor equivalent circuit diagram data are calculated from the entered rating plate data. In addition, the parameters of the controls are pre-set (subsequently optimized) (P0340 = 3).

Especially for a high thermal motor load, this adaptation has a significant influence on the degree of stability of the closed-loop vector control. For MM440 the motor temperature can only be measured using a KTY84 sensor. For the parameter setting P0601 = 0,1, the motor temperature is calculated / estimated using the thermal motor model.

The supplementary torque setpoint must always be impressed in the hoisting (raising) direction (please observe the sign!). As a result of the supplementary torque, also when lowering, a slip is immediately established that has a stabilizing effect on the closed-loop control (there is no significant load sag). ¾ The sign of the supplementary torque setpoint can be determined as follows in the commissioning phase with the appropriate care and taking into account all of the relevant safety regulations: Hoist (raise) a minimum load using the hoisting gear and read-out the sign from parameter r0079 (the sign of r0079 corresponds to the sign of the supplementary torque setpoint). ¾ An empirical value of approx. 40 % of the rated motor torque r0333 has lead to good results for existing hoisting gear (carefully observe the sign!). 0:0 CI: Supplementary torque setpoint Frequent settings: P1511=...

MICROMASTER 440 Operating Instructions 130 6SE6400-5AW00-0BP0 Issue 10/06 3 Functions 3.5.7.21 End of commissioning 0 Transfer data from RAM to EEPROM P0971 = 1 0 Inhibited 1 Start RAM->EEPROM All parameter changes are transferred from the RAM memory into the EEPROM memory and therefore saved in the MICROMASTER in a non-volatile fashion. NOTE When using a BOP or AOP, MICROMASTER automatically carries-out the RAM→EEPROM data save operation. If the parameterization is carried-out using the commissioning tools - STARTER or DriveMonitor – then data is not automatically saved in the EEPROM. Automatic RAM→EEPROM data save can be selected by pressing the appropriate selection button. STARTER DriveMonitor RAM → EEPROM Online-EEPROM END NOTE If P0971 is used to start data save from the RAM to EEPROM, then after the data has been transferred, the communications memory is re-initialized. This means that communications via USS as well as also via the CB board are interrupted for the time it takes to reset: ¾ The connected PLC (e.g. SIMATIC S7) goes into stop ¾ The STARTER start-up program buffers the communications failure ¾ For the DriveMonitor start-up program, "NC" (not connected) or "drive busy" is displayed. ¾ The "busy" text is displayed at the BOP operator panel After reset has been completed, for the start-up programs STARTER and DriveMonitor and the BOP operator panel, communications are automatically re- established. MICROMASTER 440 Operating Instructions 131 6SE6400-5AW00-0BP0 3 Functions Issue 10/06 3.5.8 Series commissioning The parameter set can be read-out (upread) from the drive converter via the serial interface and saved on the hard disk / floppy disk or in a non-volatile memory (e.g. EEPROM) using the following ¾ PC Tools (e.g. STARTER, DriveMonitor) or the ¾ Operator panel AOP (please refer to Fig. 3-28).

This means that it is possible to transfer the parameter set from drive inverter A to drive inverter B which, for identical applications (e.g. series machines, group drives) allows data to be copied and therefore in turn fast commissioning. MICROMASTER 440 Operating Instructions 132 6SE6400-5AW00-0BP0 Issue 10/06 3 Functions WARNING ¾ For series commissioning, all of the communication interfaces as well as also the digital and analog interfaces are re-initialized. This results in a brief communications failure or causes the digital outputs to switch. ¾ Potentially hazardous loads must be carefully secured before starting a series commissioning. ¾ Potentially hazardous loads can be secured as follows before starting series commissioning: ♦ Lower the load to the floor, or ♦ Clamp the load using the motor holding brake (Caution: During series commissioning, MICROMASTER must be prevented from controlling the motor holding brake). ¾ If the motor holding brake (refer to Section 3.14) is controlled by the MICROMASTER, then series commissioning may not be carried-out for potentially hazardous loads (e.g. suspended loads for crane applications). 3.5.9 Parameter reset to the factory setting The factory setting is a defined initial state of all of the drive inverter parameters. The drive inverters are shipped from the factory in this state. The drive inverters have the following default settings: ¾ Control via the digital inputs a) ON/OFF via DIN1 b) Direction of rotation reversal via DIN2 c) Fault acknowledgement via DIN3 ¾ Setpoint input via analog input 1 ¾ Signal output via the digital outputs a) Fault active via DOUT 1 b) Warning active via DOUT 2 ¾ Actual frequency via the analog output ¾ The basic V/f characteristic is the control mode (P1300 = 0) ¾ Induction motor (P0300 = 1) When appropriately connected-up and with the appropriate motor – drive inverter combination, MICROMASTER drive inverters are ready to run when shipped from the factory without requiring any additional parameterization. You can re-establish the initial state at any time by carrying-out a parameter reset to the factory setting. This undoes all of the parameter changes which were made since the drive inverter was supplied. This value is designated as "Def" in the parameter list.

These signals can be entered via a serial interface as well as also via digital inputs (refer to Fig. 3-29). MICROMASTER has 6 digital inputs which can be expanded to a total of 8 by using the 2 analog inputs. The digital inputs, as far as their assignment, can be freely programmed to create a function. Whereby, regarding the program, it is possible to directly assign the function via parameters P0701 - P0708 or to freely program the function using BICO technology.

The logical states of the digital inputs can be de-bounced using P0724 and read-out using parameter r0722 (BICO monitoring parameter). Further, this parameter is used to parameterize BICO for the digital inputs (refer to BICO parameterization in the following Section). P0701 – P0706 (digital inputs 1–6) or P0707 – P0708 (analog inputs 1-2) The possible settings of the individual inputs are listed in Table 3-11.

The output parameter number of the function (parameter, included in the parameter text BO) should be entered into the command source (parameter which contains the code BI in the parameter text). Example: An ON/OFF1 command should be realized using digital input DIN1. P0700 = 2 Control enabled via digital inputs P0701 = 99 BICO enabled for DIN1 P0840 = 722.0 ON/OFF1 via DIN1 NOTE Only experienced users should use the BICO parameterization and for applications where the possibilities provided by P0701 – P0708 are no longer adequate.

The setting as to whether the analog input is a voltage input (10 V) or a current input (20 mA) must be selected using the 2 switches DIP1(1,2) on the I/O board as well as also using parameter P0756 (refer to Fig. 3-31). Possible settings of P0756: 0 Unipolar voltage input ( 0 to +10 V ) 1 Unipolar voltage input with monitoring (0 to 10 V ) 2 Unipolar current input (0 to 20 mA) 3 Unipolar current input with monitoring (0 to 20 mA) 4 Bipolar voltage input (-10 V to +10 V) only ADC1 Fig. 3-31 DIP switch and P0756 for ADC current / voltage input NOTE ¾ The setting (analog input type) of P0756 must match that of switch DIP1(1,2) on the I/O board. ¾ The bipolar voltage input is only possible with analog input 1 (ADC1). Depending on the ADC type or source, the appropriate connection must be made. Using, as an example, the internal 10 V voltage source, a connection is shown as an example in the following diagram (refer to Fig. 3-32).

If this parameter is activated, the absolute value is always entered in the input of the DAC scaling (the DAC characteristic is mirrored on the Y axis). If the value was originally a negative one, the corresponding bit in r0785 is set for detection. NOTE The analog outputs only provide current outputs (0 ... 20 mA). A 0 ... 10 V voltage signal can be generated by connecting a 500 Ohm resistor across the outputs. The voltage drop across the resistor can be read using parameter r0774 if the parameter P0776 is changed-over from current output (P0776 = 0) to voltage output (P0776 = 1). The D/A scaling parameters P0778, P0780 and the D/A converter dead zone must still be entered in mA (0 ... 20).

These interfaces are designated as follows in the following text: ¾ BOP link ¾ COM link Different units, such as the BOP and AOP operator panels, PCs with the start-up software DriveMonitor and STARTER, interface modules for PROFIBUS DP, DeviceNet and CAN as well as programmable controls with communication processors can be connected at this interface (refer to Fig. 3-28).

Data transfer between MICROMASTER and the programming / operator units is realized using the USS protocol via the RS232 interface (point-to-point data coupling). Communications between the BOP and MICROMASTER uses a optimized interface which takes into consideration the somewhat limited resources of the BOP. If the BOP is replaced by an USS unit (PC, AOP), then MICROMASTER automatically identifies the interface of the new unit. This is also true for the inverse replacement sequence. The BOP link interface can be adapted to the particular unit using the following parameters (refer to Table 3-13). Table 3-13 BOP link BOP link – interface BOP on BOP link USS on BOP link No parameter P2009[1] r2024[1] P2010[1] r2025[1] P2011[1] r2026[1] P2012[1] r2027[1] P2013[1] r2028[1] P2014[1] r2029[1] r2015 r2030[1] P2016 r2031[1] r2032 r2033 Communication modules (CB) such as PROFIBUS, DeviceNet, CANopen and also programming / operator units (e.g. PCs with the DriveMonitor / STARTER start-up software and AOP) as well as programmable controls with communication processor can be connected to the COM link. The plug connector allows the communication modules to be connected to MICROMASTER. On the other hand, the programming / operator units must be connected to the MICROMASTER through terminals 29/30. As for the BOP link, data is transferred between MICROMASTER and the programming / operator unit using the USS protocol. In so doing, for the COM link, the USS protocol is transferred via the bus-capable RS485 interface. Essentially the same as the BOP link, the COM link also automatically defines if a communications module is replaced with a USS unit (PC, AOP). The COM link can be adapted to the particular unit using the following parameters (refer to Table 3-14).

This is the reason that the communications module has priority over USS. In this case, the USS node (USS station) via the COM link is de-activated. ¾ Contrary to PROFIBUS, the RS485 port (terminals 29/30) is not optically isolated (not floating). When installing the system, it must be ensured that EMC faults do not result in communication failures or damage to the RS485 drivers. 3.7.1 Universal serial interface (USS) Parameter range: P2009 – r2037 Significance COM link BOP link USS basic setting USS baud rate P2010[0] P2010[1] USS address P2011[0] P2011[1] USS-PZD length P2012[0] P2012[1] USS-PKW length P2013[0] P2013[1] PZD data Received data r2018[8] r2015[8] Received control word 1 r2036 r2032 Received control word 2 r2037 r2033 Sent data P2019[8] P2016[8] Sent status word 1 r0052 r0052 Sent status word 2 r0053 r0053 Alarms: --- Faults: F0071, F0072 Function chart number: FP2500, FP2510, FP2600, FP2610 Features: − electrical features: Not electrically isolated USS at the BOP link with PC- converter connecting set Not electrically isolated USS at COM link (terminals 29 /30) − cycle time (MM440): 8 ms (process data PZD) Background (parameter ID value PKW) MICROMASTER 440 Operating Instructions 146 6SE6400-5AW00-0BP0 Issue 10/06 3 Functions T T T cycle,master cycle,USS cycle,slave(MM4) Slave Master (MICROMASTER) Baud rate + interval time Telegram length Number of nodes (slave) NOTE From the user’s perspective, the total cycle time between the master and slave is of significance. As shown in the diagram above, this time depends on several factors. Fig. 3-37 Cycle times Using the USS protocol, a user can establish a serial point-to-point data link and a serial bus data link between a higher-level master system and several slave systems. Master systems can be, for example, PLCs (e.g. SIMATIC S7-200) or PCs. MICROMASTER drive converters are always the slaves on the bus system. The USS protocol allows the user to implement both automation tasks with cyclical telegram traffic (→ a fixed telegram length is necessary) as well as visualization tasks. In this case, the protocol with variable telegram length is advantageous, as texts and parameter descriptions can be transferred in one telegram without chopping up the information. MICROMASTER 440 Operating Instructions 147 6SE6400-5AW00-0BP0 3 Functions Issue 10/06 3.7.1.1 Protocol specification and bus structure The USS protocol has the following significant features: ¾ Supports ♦ a multi-point-capable link, e.g. EIA RS 485 hardware or ♦ a point-to-point link, e.g. EIA RS 232 ¾ Master-slave access technique ¾ Single-master system ¾ Maximum 32 nodes (max. 31 slaves) ¾ Operation with variable or fixed telegram length ¾ Simple, reliable telegram frames ¾ The same bus mode of operation as with the PROFIBUS (DIN 19245 Part 1) ¾ Data interface to the basic unit according to PROFILE variable-speed drives. This means that, when the USS is being used, information is transferred to the drive in the same way as with the PROFIBUS-DP. ¾ Can be used for start-up, service and automation ¾ PC-based service tools (e.g. STARTER and DriveMonitor) ¾ Can be easily implemented in customized systems Protocol specification The USS protocol defines an access technique according to the master-slave principle for communications via a serial bus. The point-to-point link is included as a sub-quantity. One master and a maximum of 31 slaves can be connected to the bus. The individual slaves are selected by the master using an address character in the telegram. A slave can never transmit without first being initiated by the master so that direct information transfer between individual slaves is not possible. The master function cannot be transferred (single-master system). The following illustration shows a bus configuration using drive technology as an example.

The telegram is terminated by the BCC (Block Check Character). ¾ For single-word data (16 bit) in the net data block (= net character block), the high byte (first character) is always sent and then the low byte (second character). ¾ The same applies to double-word data: the high word is sent first followed by the low word. ¾ The necessary settings / parameter assignments must be made both at the master as well as at the slave and can no longer be changed in bus operation. ¾ The protocol does not identify tasks in the net characters. The contents of the net characters/data for the MICROMASTER drives is discussed in Section 3.7.1.2 "Structure of the net data".

The master addresses all of the slave nodes one after the other with a task telegram. The addressed nodes respond with a reply telegram. In accordance with the master-slave procedure, the slave, after receiving the task telegram, must send the reply telegram to the master before the master can address the next slave node. The sequence of the addressed slave nodes can be specified, for example, by entering the node numbers (ADR) in a circulating list (polling list) in the master. If it is necessary to address several slaves in a faster cycle than the other slaves, their node number can occur several times in the circulating list. A point-to-point link can be implemented by means of the circulating list, in which case only one node is entered into the circulating list.

Cycle time 00 0 0 t 1 1 Telegram run time for reply from node 1 Reply delay time from node 1 Telegram run time for task for node 1 Processing time in the master Fig. 3-42 Cycle time Due to inconstant reply delay and processing times, the cycle time is not fixed. The STX start character (= 02 hexadecimal) by itself is not sufficient for the slaves to clearly identify the start of a telegram because the bit combination 02/hexadecimal can also occur in the net characters. For this reason, a no- character start interval of at least 2 character run-times before the STX is specified for the master. The start interval is part of the task telegram.

BCC Fig. 3-43 Transmit sequence The time interval between the last character of the task telegram (BCC) and the start of the reply telegram (STX) is known as the reply delay time. The maximum permissible reply delay time is 20 ms, but it must not be less than the start interval. If node x does not respond within the maximum permissible reply delay time, an error message is deposited in the master. The master than sends the telegram for the next slave node. Bus structure The data transfer medium and the physical bus interface are essentially determined by what the bus system is used for. The physical interface of the USS protocol is based on the "Recommended Standard RS-485". For point-to-point links, a sub-quantity of EIA RS-232 (CCITT V.24) or TTY (20 mA current loop) can be used as the physical interface. The USS bus is based on a linear topology without branches. Both ends of the line terminate at a node. The maximum cable length (50 m) and therefore the maximum distance between the master and the last slave is limited by the characteristics of the cable, the ambient conditions and the data transfer rate [EIA Standard RS-422- A Dezember 1978, Appendix, Page 14] The number of nodes is limited to a maximum of 33 (1 master, 32 slaves). MICROMASTER 440 Operating Instructions 152 6SE6400-5AW00-0BP0 Issue 10/06 3 Functions Master Slave Slave Maximum 32 slaves Slave First node Last node Fig. 3-44 USS bus topology The two ends of a bus line (first node and last node) must be terminated with bus terminating networks. (refer to Section 3.7.1.3). Point-to-point connections are handled just like bus connections. One node has the master function and the other has the slave function. Data is transferred in accordance with Standard EIA 485. RS 232 can be used for point-to-point links. Data transfer is always half-duplex − i.e. alternating between transmitting and receiving − and it must be controlled by the software. The half- duplex technique allows the same cables to be used for both data-transfer directions. This permits simple and inexpensive bus cabling, operation in environments subject to interference and a high data transfer rate. A shielded, twisted two-wire cable is used as the bus cable.

General structure of the net-data block The net-data block is divided into two areas: ¾ the PKW (parameter ID value) range ¾ the PZD (process data) range The structure of the net data in the USS-protocol telegram is shown below. Protocol frame Net data STX LGE ADR BCC Parameter Process data (PKW) (PZD) PKW: Parameter ID value PZD: Process data (parameter area) (process-data area) Fig. 3-45 Telegram structure ¾ The PKW area relates to the handling of the parameter ID value (PKW) interface. The PKW interface is not a physical interface but a mechanism which handles parameter transfer between two communication partners (e.g. control unit and drive). This involves, for example, reading and writing parameter values and reading parameter descriptions and associated texts. All tasks which are performed via the PKW interface essentially involve operator control and visualization, service and diagnosis. ¾ The PZD area contains the signals required for the automation system: ♦ Control word(s) and setpoint(s) from the master to the slave ♦ Status word(s) and actual value(s) from the slave to the master. PKW area PZD area PKE IND PKW elements PZD1 • • • PZD16 variable length variable length Fig. 3-46 Structure of the PKW and PZD areas The two areas together make up the net data block. This structure applies to telegrams from the master to the slave and vice versa. MICROMASTER 440 Operating Instructions 155 6SE6400-5AW00-0BP0 3 Functions Issue 10/06 PKW area With the help of the PKW mechanism, the following tasks can be performed via any serial interface with the USS protocol: ¾ Reading and writing parameters ¾ Reading the description of a parameter The PKW area can be varied. Depending on the requirements, the following lengths can be parameterized using parameter P2013: ¾ 3 words Î P2013 = 3 ¾ 4 words Î P2013 = 4 ¾ variable word length Î P2013 = 127 The following is an example of a structure when access (write/read) is made to single-word (16 bit) parameter values. The PKW area must be permanently set to 3 words at the master and the slave. This setting is made during start-up and should not be altered any more during bus operation. 1st word 2nd word 3rd word PKE IND PWE1 Index Parameter ID Parameter value 1 The following is an example of a structure when access (write/read) is made to double-word (32 bit) parameter values. Parameterization to a fixed length of 4 words applies to telegrams from the master to the slave and from the slave to the master. 1st word 2nd word 3rd word 4th word PKE IND PWE1 PWE2 Parameter ID Index Parameter value (double word) Telegram data transfer with variable telegram length (refer to the following example) means that the slave responds to a telegram from the master with a telegram whose length does not have to be the same length as the telegram from the master to the slave. 1st word 2nd word 3rd word 4th word (m+2). word . . . . . PKE IND PWE1 PWE2 With: ¾ 1 word ≤m ≤118 words (maximum) when 8 PZD words (maximum) are contained in the net data block. ¾ 1 word ≤ m ≤ 126 words (maximum) when there is no PZD. The length of elements PEW1 to PWEm in the reply telegram and what is contained in them depends on the task issued by the master. Variable length means that only the number of words necessary to pass on the appropriate information is transferred. The minimum length, however. is always 3 words. If a slave, for example, transfers a parameter value which is a 16-bit quantity (e.g. the status word in parameter r0052; data format: U16), then only 3 words of the PKW area are sent in the telegram from the slave to the master. If, for example, for MICROMASTER the actual frequency is to be read (parameter r0021), then the PKW area in the telegram from the slave to the master is 4 words large; the reason for this is that the speed is represented as 32-bit quantity (data format: Float). It is mandatory to parameterize for a variable word length, if e.g. all values are to be MICROMASTER 440 Operating Instructions 156 6SE6400-5AW00-0BP0 Issue 10/06 3 Functions read at once from an “indexed” parameter (refer to "Index", special setting, index = 255).

This fault message can only occur for the USS protocol on the technology module T 100 if basic device parameters are accessed from this interface Incorrect PKW number; only for G-SST 1/2 and SCB interface (USS). The fault number is transferred in the following two cases: ¾ If the request involves all indices of an indexed parameter (request index equal to 103 255) or the complete parameter description is requested and a variable telegram length was not parameterized. ¾ If, for the request issue, the parameterized number of PKW data in the telegram is too low (e.g.: Changing from a double word and PKW number equal to 3 (words). Parameter value not permissible; This fault number is transferred if the parameter value – that is to be transferred – is not 104 assigned any function in the device or at the time of the change it is not able to be transferred for internal reasons (although it lies within the limits).

MICROMASTER 440 Operating Instructions 161 6SE6400-5AW00-0BP0 3 Functions Issue 10/06 Parameter value (PWE) The parameter value (PWE) is transferred, depending on the parameterization of the word length (refer to parameter "USS-PKW length" P2013) of the PKW area as word or double word (32 bit). Only one parameter value can be transferred in a telegram. If the word length of the PKW area is parameterized with 3 words (P2013 = 3), then only 16-bit parameters can be transferred. Parameter descriptive elements, that are greater than 16 bit cannot be transferred. If the word length of the PKW area is parameterized to be 4 words (P2013 = 4), then 16 and 32-bit parameters can be transferred. Parameter descriptive elements that exceed 32 bits cannot be transferred. If the word length of the PKW area is parameterized with "variable length" (P2013 = 127), then 16, 32-bit parameter and parameter descriptive elements can be transferred. Further, all elements of an indexed parameter can be read or changed with a single request, as well as the complete parameter description requested if the index corresponds to the value 255 (index = 255). Transferring one 16-bit parameter value: 1. Fixed PKW area, 3 words: The value is in PWE1 2. Fixed PKW area, 4 words: The value is in PWE2 (least significant word, 4th word); PWE1 is set to 0. 3. Variable PKW area: The value is in PWE1. PWE2 and higher not available! Transferring one 32-bit parameter value: 1. Fixed PKW area, 3 words: Request is rejected with fault message 103. 2. Fixed PKW area, 4 words: PWE1 (most significant word; 3rd word) contains the high word of the double word, PWE2 (least significant word; 4th word) contains the low word of the double word. 3. Variable PKW area: As for 2.; PWE3 and higher not available! Process data area (PZD) Process data is continually exchanged between the master and slaves in this area. At the start of communications it is configured as to which process data is to be exchanged with a slave. For instance, for slave x, the current setpoint is to be transferred in the second PZD (= PZD2). This setting remains for the complete data transfer. 1 word 1 word 1 word 1 word 1 word PZD1 PZD2 PZD3 PZD4 . . . . . PZD8 PZD1 – PZD8 = process data = control / status word(s) and setpoint / actual value(s)); The control / status word(s), setpoints and actual values required for the automation are transferred in this area. The length of the PZD area is defined by the number of PZD elements (P2012). Contrary to the PKW area, that can be variable, the length of this area between the communication partners (master and slave) must always be permanently declared. MICROMASTER 440 Operating Instructions 162 6SE6400-5AW00-0BP0 Issue 10/06 3 Functions The maximum number of PZD words per telegram is, for MICROMASTER, limited to 8 words (USS-PZD length in MICROMASTER is set using parameter P2012). If only PKW data are to be transferred in the net data block, then the number of the PZD can also be 0! Depending on the data transfer direction, always control word 1 or status word 1 are to be transferred in the PZD1. Depending on the data transfer direction, the main setpoint or the main actual value is always transferred in PZD 2. Additional setpoints or actual values are set in the following process data PZD3 to PZDn. For MICROMASTER, if required, control word 2 or status word 2 should be transferred in PZD4.

The appropriate de-normalization is implemented by assigning the appropriate parameters. ¾ If MICROMASTER sends data to the master via the PZD area, then for physical quantities, a normalization is made to a 16-bit value (4000 hex notation). ¾ The setpoint can be freely assigned to the actual value; This means for example that the frequency setpoint is transferred in the request telegram in PZD2 so the actual frequency value can be signaled back in PZD2 in the response telegram (this also makes sense from a technological/process perspective); or however, also another actual value – such as the actual torque value, actual voltage actual value or actual current value. The setpoint can be freely assigned to the actual value; for example the frequency setpoint is transferred in the request telegram in PZD2, which means that the actual frequency value can be signaled back in the response telegram in PZD2 (this also makes sense from a technological/process perspective) – or also another actual value – such as actual torque value, actual voltage value or actual current value.

In this case, the bus cable from the first USS device [node] up to the last USS device [node] should be considered as one bus cable – so that the USS bus should be terminated twice. For the first bus node [device] (e.g. master) and last bus node [device] (e.g. drive converter), th bus terminating resistor must be switched-in. NOTE ♦ When supplied, the bus terminating resistors are not switched-in! ♦ Please note that you only switch-in the bus terminating at the first bus node [device] and last bus note [device]! The bus terminating resistors should be always set with the system in a no-voltage state (e.g. powered-down)! ♦ Data transfer errors on the bus are possible! In active bus operation, devices where the terminating resistor is switched-in, may not be in a no-voltage state. The terminating resistor draws the voltage from the connected device. This is the reason that the terminating resistor is no longer effective when the device is in a no-voltage state (e.g. when powered down) .

A terminating resistor between P+ and N- at both bus ends (refer to Fig. 3-48) Control terminals +10 V 0 V P+ N- 1 2 29 30 RS485 terminator to terminal 2 of the next slave Fig. 3-48 Connecting the RS485 terminator If the frequency inverter is the last slave on the bus (refer to Fig. 3-47), then the P+ and N- of the RS485 terminator provided must be connected there to the RS485 terminals (refer to Fig. 3-48). P10 and 0 V can be connected to terminals 1 and 2 for the power supply. If the frequency inverter is the first slave, then the bus should only be terminated there with P+ and N- (120 Ω). If the first or last bus node is not a MICROMASTER 4, then the bus between P+ and N– must be terminated with a resistor (between 120 Ω and 220 Ω). The bus must be operated with a bias on one or on both ends (pull-up resistance from P+ to P5 or P10, pull-down resistance from N– to 0 V). If the first or last bus node is not a MICROMASTER 4 (e.g. a controller of the S7-200 series), the bus can then be biased by connecting 390 Ω resistors from P+ to P5 and from N– to 0 V. If the first or last bus node is a controller of the S7-200 series, SIMATIC PROFIBUS connectors, e.g. 6ES7972-0BA41-0XA0, can be used for the bias and the termination. MICROMASTER 440 Operating Instructions 165 6SE6400-5AW00-0BP0 3 Functions Issue 10/06 NOTE ¾ When making the installation it must be ensured that EMC disturbances/noise cannot result in communication failures/errors or damage to the RS485 drivers. As a minimum, the following measures must be taken: 1) Shield the motor cable and correctly ground the shield at both ends. If at all possible, avoid interruptions in the cables. If this cannot be avoided, then it must be ensured that the shield continues in an EMC-correct fashion at the connecting locations. 2) All node points must be well grounded (EMC ground). 3) All relay coils must be provided with noise suppression elements. 4) The cables should be routed - as far as possible - separately from other cables. For RS485 cables it is especially important that they are kept well away from motor cables. 5) The shields of RS485 cables must be correctly grounded. ¾ If the AOP communicates via the USS protocol, then contrary to the BOP, the appropriate USS parameters (Table 3-13 and Table 3-14) should be set. ¾ For error-free communications, the appropriate communication parameters must be harmonized with one another and correctly set - in the frequency inverter, the connected device and/or in the connected option board. Please refer to the corresponding Operating Instructions for the AOP and for the communications modules. ¾ While RS485 communications is operational the power supply must always be available using pull-up/pull-down resistors.

The fixed frequencies are defined using parameters P1001 – P1015 and selected via binector inputs P1020 – P1023, P1025, P1026. The effective fixed frequency setpoint is available via connector output r1024 which means that it can be connected further. If this is to be used as setpoint source, then either parameter P1000 or P0719 should be modified or BICO parameter r1024 should be connected to the main setpoint P1070 or supplementary setpoint P1075. Contrary to parameter P0719, when parameter P1000 is modified, this implicitly changes BICO parameters P1070, P1075. Example: Fixed frequencies as setpoint source a) Standard method → P1000 = 3 b) BICO method → P1070 = 1024, P1075 = 0 3 methods are available when selecting the fixed frequencies. Direct selection In this particular mode, the control signal directly selects the fixed frequency. This control signal is entered via the binector inputs. If several fixed frequencies are simultaneously active, then the selected frequencies are added.

These 4 control signals are either entered via digital inputs or a serial communications interface.

The motorized potentiometer value is adjusted using the "Raise" and "Lower control signal" which is selected using BICO parameters P1035 and P1036 (refer to Fig. 3-51). The value which has been set is available through connector output r1050 so that it can be further connected and used. Fig. 3-51 Motorized potentiometer Selecting via serial interfaces The MOP functionality can be selected via the operator panels (refer to Section 3.2), digital inputs as well as via serial interfaces (refer to the example). Parameterization is also possible directly using BICO parameters P1035 and P1036 as well as also parameters P0700 and P0719. In this case, for a value assigned to P0700, the BICO parameter is appropriately modified. Example: Command source via "USS on BOP link" interface a) Standard method → P0700 = 4 b) BICO method → P1035 = 2032.13 P1036 = 2032.14 :::: (refer to P0700 for a complete list) MICROMASTER 440 Operating Instructions 170 6SE6400-5AW00-0BP0 Issue 10/06 3 Functions If the motorized potentiometer is to be used as setpoint source, then either parameter P1000 or P0719 should be modified or the BICO parameter r1050 should be connected to the main setpoint P1070 or supplementary setpoint P1075.

The JOG mode can be selected either using the operator panel (refer to Section 3.2), digital inputs or also via the serial interfaces (refer to the example). An ON/OFF command is not used to move the drive, but when the "JOG keys" are pressed. These "JOG keys" are selected using the BICO parameters P1055 and P1056.

When a key is pressed, the drive inverter accelerates the motor to the fixed frequency in the time entered in P1060. This frequency is only exited after the key has been cancelled and the drive then brakes down to 0 Hz in the time entered in P1061. In addition to the explicit parameterization (P1055 and P1056), the JOG functionality is also enabled via parameter P0700 or P0719 (implicit parameterization). In this case, if a value is assigned to P0700, the BICO parameter is appropriately modified.

This can be used to control process quantities – such as pressure or level. Depending on the application, different control structures are required to control process quantities. For MICROMASTER, the following structures have been integrated; these can be selected or de-selected using parameters P2200, P2251 (also refer to Fig. 3-53): a) Variable-speed drive (VSD) b) Closed-loop PID control c) Closed-loop dancer roll control The PID controller – integrated in MICROMASTER – is required for control structures b) and c). The frequency inverter can address many new applications using the higher-level control (closed-loop PID/dancer roll control).

Similar to the PID setpoint branch, the actual value branch of the technological controller has a filter (PID-PT1) which can be set using parameter P2265. In addition to the smoothing, the actual value can be modified using a scaling unit (PID-SCL).

It is also important that no folds or creases are formed. For applications such as these, it is practical to provide a type of material buffer in the form of a loop with a defined tension. This provides a de- coupling between the individual drive locations. This loop represents the difference between the material fed-in and that fed-out and therefore indicates the process quality. Using the PID dancer roll control, with MICROMASTER 440 it is possible to ensure that continuous material webs have a constant tension. v v 2 1 x 2 Motor SUM v * AFM RFG 2 setpoint control PID PID PID x * PID 2 limit setpoint RFG − PID x 2 feedback Fig. 3-57 PID dancer roll control The velocity v is assumed to be an independent disturbance; the input velocity v 1 2 should be controlled using drive rolls A so that the length x of the loop 2 2 corresponds, as far as possible, to the setpoint.

MICROMASTER has a special characteristic which allows the setpoint to be entered simultaneously from two setpoint sources.

For MICROMASTER, this can be very elegantly realized using the summation point where the main and supplementary (additional) setpoint are added in the setpoint channel. In this case, both quantities are simultaneously read-in via two separate or one setpoint source and summed in the setpoint channel. Depending on external circumstances, the supplementary setpoint can be dynamically disconnected or switched-in to the summation point (refer to Fig. 3-60). This functionality can be used to advantage, especially for discontinuous processes.

BICO parameterization - P1070 CI: Main setpoint - P1075 CI: Additional setpoint Further, the main setpoint as well as the supplementary (additional) setpoint can be scaled independently of one another. In this case, for example, a user can simply implement an override function using the appropriate parameterization. A scan sequence is generally associated with a forwards and a backwards motion. When selecting the reversing functionality, after reaching the end position, a direction of rotation reversal can be initiated in the setpoint channel (refer to Fig. 3-61). On the other hand, if it is to be prevented that a direction of rotation reversal or a negative frequency setpoint is to be entered via the setpoint channel, then this can be inhibited using BICO parameter P1110.

These resonance points result in oscillations which, under worst case conditions, can damage the driven load. Using suppression frequencies, MICROMASTER allows these resonant frequencies to be passed through as quickly as possible. This means that the suppression frequencies increase the availability of the driven load over the long term.

This therefore helps to reduce the stressing on the mechanical system of the machine. An acceleration ramp and a braking ramp can be set independently of one another using the ramp-up time P1120 and the ramp-down time P1121. This allows a controlled transition when the setpoint is changed (refer to Fig. 3-62). f f max f 2 f t 1 P1120 P1121 f f max f 2 f 1 P1130 P1131 P1132 P1133 t t t up down - 1 f 2 f1 ⋅ P1120 ≥ (P1130 + P1131) for P1082 2 1 - f 2 f1 = + + ⋅ P1120 (P1130 P1131) tup 2 P1082 - 1 f 2 f1 ⋅ P1121 ≥ (P1132 + P1133) for P1082 2 1 - f f 2 1 = (P1132 + P1133) + ⋅ P1121 t down 2 P1082 Where the rounding times are increased to be greater than the ramp period then the ramp period is determined by the following equations: 2 ⎛ ⎞ 2 ⋅() − ⋅() P1120 ⋅P1130 ⎛ P1131⎞ f f 2 1 ⎜ ⎟ = ⋅⎜1+ ⎟ t up ⎜ ⎟ ⎜ ⎟ ⋅() P1130 + P1131 P1130 fmax ⎝ ⎠ ⎝ ⎠ 2 ⎛ ⎞ 2 ⋅() − ⋅() P1120 ⋅P1132 ⎛ P1133⎞ f f 2 1 ⎜ ⎟ = ⋅⎜1+ ⎟ t down ⎜ ⎟ ⎜ ⎟ ⋅() P1132 + P1133 P1132 f max ⎝ ⎠ ⎝ ⎠ Fig. 3-62 Ramp-function generator MICROMASTER 440 Operating Instructions 6SE6400-5AW00-0BP0 183 With rounding Without rounding 3 Functions Issue 10/06 In order to avoid torque surges at the transitions (constant velocity phase ←→ accelerating / braking phase), additional rounding-off times P1130 – P1133 can be programmed. This is especially important for applications (e.g. transporting/pumping liquids or for cranes) which require an especially "soft", jerk- free acceleration and braking. If the OFF1 command is initiated while the drive is accelerating, then rounding-off can be activated or de-activated using parameter P1134 (refer to Fig. 3-63). These rounding-off times are defined using parameters P1132 and P1133.

P1142 BI: RFG enable setpoint If the binary signal = 0, then the ramp-function generator input is set to 0 and the output is reduced to 0 via the ramp-function generator ramp. The ramp-function generator itself is enabled after the pulses have been enabled (inverter enable) and after the excitation time has expired (P0346). After limiting to the maximum speeds for the positive and negative directions of rotation (P1082, - P1082 or 0 Hz for the direction of rotation inhibit) the setpoint speed for the control is obtained (r1170). NOTE The maximum frequency of the setpoint channel is set using parameter P1080. In V/f mode the maximum frequency is 650 Hz. In vector mode the maximum frequency it is limited to 200 Hz (r1084).

The machine operator carries-out the preparatory activities for subsequent automatic operation in the manual mode. In the manual mode, the machine operator locally controls the machine (enters the ON/OFF command as well as also the setpoint). A changeover is only made into the automatic mode after the set-up has been completed. In the automatic mode, the control (open-loop) of the machines and production processes are handled by a higher-level control system (e.g. PLC). This operation is maintained until it is necessary to again load and unload the machine or feed new material into the machine or production process. For MICROMASTER 440, indexed parameters P0700 or P1000 and BICO parameters P0810 and P0811 are used to changeover (toggle between) the manual/automatic modes. The command source is defined using P0700 and the setpoint source is defined using P1000 (refer to Table 3-30), whereby index 0 (P0700[0] and P1000[0]) defines the automatic mode and index 1 (P0700[1] and P1000[1]) the manual mode. BICO parameters P0810 and P0811 are used to changeover (toggle between) the automatic and manual modes. These BICO parameters can be controlled from any control source (refer to Table 3-29). In so doing, in addition to P0700 and P1000, also all of the other CDS parameters are changed over (manual/automatic changeover is generalized as a CDS changeover).

This interlocking logic couples several states (e.g. access control, plant/system state) to form a control signal (e.g. ON command). Previously this was implemented using either a PLC or relays. This represented additional costs for the plant or system. In addition to logic operations, increasingly, arithmetic operations and storage elements are required in drive inverters which generate a new unit from several physical quantities.

Before opening the brake, the pulse inhibit must be removed and a current impressed which keeps the drive in that particular position. In this case, the impressed current is defined by the min. frequency P1080. A typical value in this case is the rated motor slip r0330. In order to protect the motor holding brake from continuous damage, the motor may only continue to move after the brake has been released (brake release times lie between 35 ms and 500 ms). This delay must be taken into account in parameter P1216 "Holding brake release delay" (refer to Fig. 3-68). Fig. 3-68 Motor holding brake after ON / OFF1 MICROMASTER 440 Operating Instructions 196 6SE6400-5AW00-0BP0 Issue 10/06 3 Functions The motor holding brake is either closed using OFF1 / OFF3 or OFF2. For OFF1 / OFF3, when the minimum frequency P1080 is reached, the motor is operated at this frequency until the brake has been applied (closing times of brakes lie between 15 ms and 300 ms). The actual time is specified using parameter P1217 "Holding time after ramp down" (refer to Fig. 3-68). If, on the other hand, an OFF2 command has been output, then independent of the drive state, the status signal r0052 bit 12 "Motor holding brake active" is reset. This means that the brake immediately closes after OFF2 (refer to Fig. 3-69).

This signal can be output as follows: ¾ Via digital outputs The status signal is output via the digital output. In this case, the internal MICROMASTER relay (if the specification is sufficient) or also an external contactor or relay can be used to control the brake. ¾ Via status signal using the serial interface (USS or PROFIBUS) The master must process the status signal. The signal must be connected to the digital output of the master to which the contactor / relay for the motor holding brake is connected. MICROMASTER 440 Operating Instructions 6SE6400-5AW00-0BP0 197 3 Functions Issue 10/06 NOTE ¾ Motors have optional holding brakes which are not designed to be used as brakes for normal operation. The holding brakes are only designed for a limited number of emergency braking operations / motor revolutions with the brake closed (refer to the Catalog data). ¾ When commissioning a drive with integrated holding brake it is therefore absolutely imperative that it is ensured that the holding brake functions perfectly. A "clicking noise" in the motor indicates that the brake has been correctly released. ¾ Parameter settings: ♦ To open/close, the digital output controls the motor holding brake at point 1/2 (refer to Fig. 3-68). In this case the prerequisite is that the motor holding brake P1215 has been activated as well as the selection of the motor holding brake at the digital output. ♦ Brake opening time P1216 is greater than/equal to the time to open the holding brake. ♦ Brake delay time P1217 is greater than/equal to the time to close the holding brake. ♦ Select the min. frequency P1080 so that it acts just like a weight equalization function. ♦ A typical value for the min. frequency P1080 for the motor holding brake is the slip frequency of the motor r0330. The rated slip frequency can be calculated using the following formula: r0330 nsyn − nn fSlip[Hz] = ⋅ P0310 = ⋅ fn 100 nsyn ♦ The following control parameters should be noted in conjunction with the motor holding brake: − for V/f control (open-loop) P1310, P1311, P1333, P1335 − for closed-loop vector control (SLVC) P1610, P1611, P1750, P1755 MICROMASTER 440 Operating Instructions 198 6SE6400-5AW00-0BP0 Issue 10/06 3 Functions WARNING ¾ It is not sufficient to select the status signal r0052 bit 12 "Motor holding brake active" in P0731 – P0733. In order to activate the motor holding brake, in addition, parameter P1215 must also be set to 1. ¾ If the frequency inverter controls the motor holding brake, then a commissioning may not be carried-out for potentially hazardous loads (e.g. suspended loads for crane applications) unless the load has been secured. Potentially hazardous loads can be secured as follows before commissioning is started: ♦ Lower the load to the floor ♦ During the commissioning phase or after the frequency inverter has been replaced, the frequency inverter must be inhibited from controlling the motor holding brake (it is not permissible that the frequency inverter controls the holding brake). Quick commissioning or a parameter download using STARTER etc. may only be carried-out after this has been absolutely ensured. The motor holding brake terminals can then be re-assigned (in this case, it is not permissible that digital output P0748 is inverted for the motor holding brake). ♦ In order to hold the motor against the mechanical brake at a specific frequency, it is important that the min. frequency P1080 approximately corresponds to the slip frequency. If the value is selected to be too high, then the current drawn can be too high so that the frequency inverter shuts- down (trips) due to an overcurrent. If the value selected is too low, then it is possible that not enough torque is produced to hold the load. ¾ It is not permissible to use the motor holding brake as operating brake. The reason for this is that generally it is only dimensioned/designed for a limited number of emergency braking operations. Motor with motor holding brake (example) A motor with motor holding brake for a hanging (suspended) axis is connected to st the frequency inverter. This holding brake is to be controlled using the 1 digital output. Which settings have to be made? ¾ Select the "motor holding brake active" function (52.12) at digital output P0731. ¾ Activate the brake sequence control in the frequency inverter (P1215 = 1). ¾ Set parameter P1216 to open the holding brake after an ON command. The brake opening time P1216 must be set so that it is equal to or longer than the time required to open the holding brake. The opening time of the brake (refer to the Motor Catalog, e.g. M11) plus the relay opening time can be used as nominal value for P1216. ¾ Set parameter P1217 to close the holding brake after an OFF1/3 command. The brake delay time P1217 must be set so that it is equal to or longer than the time required to close the holding brake. The closing time of the brake (refer to Motor Catalog, e.g. M11) plus the relay closing time can be used as nominal value for P1217. ¾ Set the load holding The opening / closing times of mechanical brakes are subject to certain fluctuations; this is the reason that a weight equalization function must be parameterized in the frequency inverter for the time P1216 and P1217. The following parameters must be defined so that the axis cannot sag (i.e. the axis cannot drop/fall).

This increase can be prevented using dynamic braking (refer to Section 3.15.3; P1237). In order that there is no negative effect when using dynamic braking, the following functions should be disabled for hoisting gear applications: ♦ Vdc_max controller P1240 ♦ Compound brake P1236 MICROMASTER 440 Operating Instructions 6SE6400-5AW00-0BP0 201 3 Functions Issue 10/06 3.15 Electronic brakes MICROMASTER 440 has 3 electronic brakes: DC braking (refer to Section 3.15.1) Compound braking (refer to Section 3.15.2) Dynamic braking (refer to Section 3.15.3) These brakes can actively brake the drive and avoid a possible DC link overvoltage condition.

A "flat" ramp must be selected so that the drive inverter is not tripped (shutdown) due to the high regenerative energy which would cause a DC link overvoltage condition. The DC brake should be activated while the OFF1 / OFF3 command is present if the drive is to be braked faster. For DC braking, instead of continually reducing the output frequency / voltage during the OFF1 / OFF3 phase, from a selectable frequency, a DC voltage / current is input (refer to sequence a). The drive can be brought to a standstill in the shortest time using DC current braking (DC brake). DC braking is selected as follows: ¾ After OFF1 or OFF3 (the DC brake is released via P1233) Sequence ℵ ¾ Directly selected using BICO parameter P1230 Sequence ℑ For DC braking, a DC current is impressed in the stator winding which results in a significant braking torque for an induction motor. The magnitude, duration and frequency at which braking starts can be set for the braking current and therefore braking torque by setting the appropriate parameters. MICROMASTER 440 Operating Instructions 202 6SE6400-5AW00-0BP0 Issue 10/06 3 Functions The DC brake can therefore support a braking operation from approx. < 10 Hz or prevents / minimizes the increase in the DC link voltage for regenerative braking. This is realized because energy is directly absorbed in the motor. The essential advantage and the main application of the DC brake is the fact that a holding torque can be generated at standstill (0 Hz). For instance, this is important for applications where after positioning, any motion in the mechanical system / product itself can result in waste. DC braking is especially used for: ¾ Centrifuges ¾ Saws ¾ Grinding machines ¾ Conveyor belts Sequence ℵ 1. Enabled using P1233 2. DC braking is activated with the OFF1 or OFF3 command (refer to Fig. 3-73) 3. The drive inverter frequency is ramped-down along the parameterized OFF1 / OFF3 ramp down to the frequency at which DC braking is to start - P1234. This means that the kinetic energy of the motor can be reduced without endangering the drive. However, if the ramp-down time is too short, there is a danger that a fault will be output as a result of an overvoltage condition in DC link - F0002. 4. The inverter pulses are inhibited for the duration of the de-magnetizing time P0347. 5. The required braking current P1233 is then impressed for the selected braking time P1232. The status is displayed using signal r0053 bit 00. The inverter pulses are inhibited after the braking time has expired. 1 ON OFF1/OFF3 t P0347 OFF2 tt ?f?

After DC braking has been cancelled, the drive accelerates back to the setpoint frequency until the motor speed matches the drive inverter output frequency. If there is no match, then there is danger that a fault will be output as a result of overcurrent - F0001. This can be avoided by activating the flying restart function.

If the DC link voltage exceeds the compound switch-in threshold V (refer to Fig. 3-75), then a DC current is impressed as a function DC-Comp of P1236. In this case, braking is possible with a controlled (closed-loop) motor frequency and minimum regenerative feedback. Effective braking is obtained without having to use additional components by optimizing the ramp-down time (P1121 for OFF1 or when braking from f to f , P1135 for OFF3) and using 1 2 compound braking P1236.

MICROMASTER 440 Operating Instructions 6SE6400-5AW00-0BP0 205 3 Functions Issue 10/06 WARNING ¾ For compound braking, regenerative braking is superimposed on the DC braking (braking along a ramp). This means that components of the kinetic energy of the motor and driven load are converted into thermal energy in the motor. If this power loss is too high or if the braking operation takes too long, then this can cause the drive to overheat ! ¾ When using compound braking it must be expected that there is a higher level of noise above the compound braking switch-in threshold.

Examples of these applications include: ¾ Cranes ¾ Traction drives ¾ Conveyor belts which transport loads downwards When the motor is in the regenerative mode, the energy from the motor is fed back into the DC link of the drive converter via the inverter. This means that the DC link voltage increases and when the maximum threshold is reached, the drive inverter is shutdown (tripped) with fault F0002. This shutdown (trip) can be avoided by using dynamic braking. Contrary to DC and compound braking, this technique requires that an external braking resistor is installed. MICROMASTER 440 Operating Instructions 206 6SE6400-5AW00-0BP0 Issue 10/06 3 Functions The advantages of dynamic resistor braking include: ¾ The regenerative energy is not converted into heat in the motor ¾ It is significantly more dynamic and can be used in all operating states (not only when an OFF command is output) Chopper resistor MM4 B+ B- = = Chopper ~ control ~ ~ Fig. 3-76 Connecting the chopper (braking) resistor The braking energy in the DC link is converted into heat when dynamic braking is activated (enabled using P1237). The energy is converted into heat using the voltage-controlled chopper resistor (ballast resistor). Chopper resistors are used if regenerative energy is dissipated in the DC link for a short time, e.g. when a drive brakes and the drive should be prevented from being shutdown (tripped) with fault message F0002 ("DC link overvoltage"). In this case, when the DC link threshold V is exceeded, then the chopper resistor is switched-in using an electronic DC chopper switch (semiconductor switch). Switch-in threshold of the chopper resistor: If P1254 = 0 : VDC,Chopper =1.13 ⋅ 2 ⋅ Vline sup ply =1.13 ⋅ 2 ⋅P0210 Otherwise : VDC,Chopper = 0.98 ⋅r1242 The chopper switch-in threshold V is calculated as a function of parameter DC chopper P1254 (Auto detect V switch-on levels), either directly using the line supply DC voltage P0210 or indirectly using the DC link voltage and r1242. 100 % V DC, act 0 x x t = ⋅ t Chopper, ON Chopper ∆V 100 – V 1 V DC, Chopper 1 0 P1237 1 Alarm Duty cycle A0535 monitoring 0 Mains 200 - 240 V 380 - 480 V 500 - 600 V ∆ V 9.8 V 17.0 V 21.3 V Fig. 3-77 Mode of operation of the dynamic braking MICROMASTER 440 Operating Instructions 6SE6400-5AW00-0BP0 207 3 Functions Issue 10/06 The regenerative (braking) energy is converted into thermal energy using the chopper resistor. A braking module (chopper control) is integrated in the DC link for this purpose. The chopper of the braking module switches the resistor with a mark- space ratio corresponding to the regenerative power to be dissipated. The braking module is only active if, as a result of the regenerative operation, the DC link voltage lies above the chopper switch-in threshold V . This means that the DC chopper braking module is not active in normal operation when motoring. The chopper resistor is only designed for a specific power and a certain load duty cycle and can only absorb a limited amount of braking energy within a specific time period. The chopper resistors, specified in MICROMASTER Catalog DA51.2, have the following load duty cycle. Power P 1 100 P 0.05 DB t [s] 12 240 P = continuous power DB = 20 ⋅ P P = permissable power for 12 s every 240 s 100 DB Fig. 3-78 Load duty cycle – chopper resistors (MICROMASTER Catalog DA51.2) This load duty cycle (P1237 = 1 → 5 %) is saved in MICROMASTER. If the values are exceeded due to the load required, then when the maximum acceptable braking energy is reached, the load duty cycle monitoring controls the chopper so that the value is reduced to the value entered in parameter P1237. This means that the energy to be dissipated in the chopper resistor is reduced which means that the DC link voltage quickly increases due to the regenerative energy available and the drive inverter is shutdown (tripped) due to a DC link overvoltage condition. If the continuous power or the load duty cycle for a resistor is too high, then the continuous rating can be quadrupled using 4 resistors in a bridge circuit configuration. In this case, in addition, the load duty cycle must be increased using parameter P1237 from P1237 = 1 (→ 5 %) to P1237 = 3 (→ 20 %). When using the bridge circuit, the overtemperature switch of the resistors should be connected in series and incorporated in the fault circuit. This guarantees, that when a resistor overheats, the complete system / drive inverter is shut down.

In this case, an external braking unit must be used. ¾ When operational, the temperature of braking resistors increases – do not touch ! Ensure that there is sufficient clearance around the unit and there is adequate ventilation. ¾ A temperature protection switch must be used to protect the units against overheating. MICROMASTER 440 Operating Instructions 210 6SE6400-5AW00-0BP0 Issue 10/06 3 Functions 3.16 Automatic restart Parameter range: P1210 P1211 Warnings A0571 Faults F0035 Function chart number: - After a power failure (F0003 "Undervoltage"), the "Automatic restart" function (enabled using P1210) automatically powers-up the drive inverter again. Any faults are automatically acknowledged by the drive inverter. When it comes to power failures (line supply failure), then a differentiation is made between the following conditions: Line undervoltage (brownout) "Line undervoltage" is a situation where the line supply is interrupted and returns before (if installed) the BOP display has gone dark (this is an extremely short line supply interruption where the DC link hasn't completely collapsed). Line failure (blackout) "Line failure" is a situation where the display has gone dark (this represents a longer line supply interruption where the DC link has completely collapsed) before the line supply returns. The automatic restart function P1210 is shown in the following diagram (refer to Fig. 3-81) as a function of external states / events.

The number is internally decremented after each unsuccessful attempt. After all attempts have been made (as specified in parameter P1211), automatic restart is cancelled with message F0035. After a successful start attempt, the counter is again reset to the initial value. NOTE ¾ The "Flying restart" function (refer to Section 3.17) must be additionally activated if, for an automatic restart, the drive inverter is to be connected to a motor which may already be spinning. DANGER ¾ For longer line supply failures (blackouts)and when the automatic restart function is activated, over a longer period of time it may be assumed that MICROMASTER is powered-down. However, when the line supply returns, motors can automatically start to run again without any operator intervention. ¾ If the operating range of the motors is entered in this status, this can result in death, severe injury or material damage. MICROMASTER 440 Operating Instructions 212 6SE6400-5AW00-0BP0 Issue 10/06 3 Functions 3.17 Flying restart Parameter range: P1200 P1202, P1203 r1204, r1205 Warnings - Faults - Function chart number: - The "Flying restart" function (this is enabled using P1200, refer to Table 3-33) allows the drive inverter to be switched to a motor which is still spinning. If the drive inverter was to be powered-up without using the flying restart function, there would be a high possibility that a fault with overcurrent F0001 would occur. The reason for this is that the flux must first be established in the motor and the V/f control or closed-loop Vector control must be set corresponding to the actual motor speed. The drive inverter frequency is synchronized with the motor frequency using the flying restart function. When the drive inverter is normally powered-up it is assumed that the motor is stationary and the drive inverter accelerates the motor from standstill and the speed is ramped-up to the setpoint which has been entered. However, in many cases this condition is not fulfilled. A fan drive is a typical example. When the drive inverter is powered-down the air flowing through the fan can cause it to rotate in any direction.

In so doing, the parameterizable search current P1202 is impressed. If the search frequency is close to the rotor frequency, the DC link current suddenly changes because the flux in the motor establishes itself. Once this state has been reached, the search frequency is kept constant and the output voltage is changed to the voltage value of the V/f characteristic with the magnetizing time P0346 (refer to Fig. 3-82). MICROMASTER 440 Operating Instructions 6SE6400-5AW00-0BP0 213 3 Functions Issue 10/06 ¾ Closed-loop Vector control without encoder (SLVC): Starting from the initial value, the search frequency approaches the motor frequency with the impressed current P1202. The motor frequency has been found if both frequencies coincide. The search frequency is then kept constant and the flux setpoint is changed to the rated flux with the magnetizing time constant (dependent on P0346). After the magnetizing time P0346 has expired, the ramp-function generator is set to the speed actual value and the motor is operated with the actual reference frequency. f f search,max Setpoint frequency t Flying restart Magnetizing Ramp up Demagnetizing time P1202 time P1203 P0346 P0347 Fig. 3-82 Flying restart Flying restart with speed encoder Depending on parameter P1200, after the de-magnetizing time P0347 expires a) After the line supply returns with the automatic restart active, or b) After the last shutdown using the OFF2 command (pulse inhibit) flying restart is started with the maximum search frequency f . search,max ¾ V/f characteristic (P1300 < 20): For V/f control, the output voltage of the drive inverter is linearly increased from 0 to the V/f characteristic value within the magnetizing time P0347. ¾ Closed-loop Vector control with speed encoder (VC): For the closed-loop Vector control, the necessary magnetizing current is established within the magnetizing time P0347. After the magnetizing time P0346 has expired, the ramp-function generator is set to the speed actual value and the motor is operated at the actual setpoint frequency. NOTE ¾ If a higher value is entered for the search velocity P1203 this results in a flatter search curve and therefore to an extended search time. A lower value has the opposite effect. ¾ For "Flying restart", a braking torque is generated which can cause drives, with low moments of inertia, to brake. ¾ For group drives, "Flying restart" should not be activated due to the different characteristics of the individual motors when coasting down. WARNING ¾ When "Flying restart" is activated (P1200 > 0), although the drive is at a stand- still and the setpoint is 0, it is possible that the drive is accelerated as a result of the search current ! ¾ If the operating range of the motors is entered when the drive is in this state, this can result in death, severe injury or material damage. MICROMASTER 440 Operating Instructions 214 6SE6400-5AW00-0BP0 Issue 10/06 3 Functions 3.18 Closed-loop Vdc control In addition to DC, compound and dynamic braking, for MICROMASTER it is possible to prevent a DC link overvoltage condition using the closed-loop Vdc controller. With this technique, the output frequency is automatically modified during operation using the closed-loop Vdc controller so that the motor doesn't go too far into the regenerative mode. DC link overvoltage ¾ Cause: The drive regenerates and feeds too much energy back into the DC link. ¾ Remedy: The DC link voltage is further reduced using the Vdc_max controller (refer to Section 3.18.1) by reducing the regenerative torque down to zero. Using the Vdc controller, it is also possible to prevent the drive converter being shut down (tripped) during brief line supply dips – which cause a DC link undervoltage condition. Also in this case, the output frequency is automatically modified by the Vdc controller during operation. Contrary to an overvoltage condition, in this case the motor is operated with increased regenerative operation in order to support and buffer the DC link voltage. DC link undervoltage ¾ Cause: Line supply voltage failure or dip (blackout or brownout) ¾ Remedy: A regenerative torque is entered for the operational drive which compensates the existing losses and therefore stabilizes the voltage in the DC link. This technique is carried-out using the Vdc_min controller (refer to Section ) and is known as kinetic buffering. 3.18.1 Vdc_max controller Parameter range: P1240, r0056 bit 14 r1242, P1243 P1250 – P1254 Warnings A0502, A0910 Faults F0002 Function chart number: FP4600 A brief regenerative load can be handled using this function (enabled using P1240) without the drive inverter being shut down (tripped) with fault message F0002 ("DC link overvoltage"). In this case, the frequency is controlled (closed-loop) so that the motor doesn't go too far into regenerative operation. If the drive inverter regenerates too much when braking the machine due to a fast ramp-down time P1121, then the braking ramp / ramp time are automatically extended and the drive inverter is operated at the DC link voltage limit r1242 (refer to Fig. 3-83). If the DC link threshold r1242 is again fallen below, then the Vdc_max controller withdraws the extension of the braking ramp. MICROMASTER 440 Operating Instructions 6SE6400-5AW00-0BP0 215 3 Functions Issue 10/06 V DC r1242 t V -controller active DC_max A0911 1 r0056 Bit 14 0 t ⏐f⏐ f act f set t Fig. 3-83 Vdc_max controller On the other hand, if the Vdc_max controller increases the output frequency (e.g. for a steady-state regenerative load), then the Vdc_max controller is disabled by an internal drive inverter monitoring function and warning A0910 is output. If the regenerative load continues, the drive inverter is protected using fault F0002. In addition to controlling the DC link (closed-loop), the Vdc_max controller supports the stabilizing processes of the speed at the end of an acceleration phase. This is especially the case if there is an overshoot and the motor therefore briefly goes into regenerative operation (damping effect). The automatic increase of the braking ramp (refer to Fig. 3-83) can be contradictory to the objective of the application. This behavior is not required, especially for positioning drives and hoisting gear (e.g. cranes). A DC link overvoltage condition can still be avoided by disabling the Vdc-max controller (P1240 = 0) and by activating the following functions: ¾ Extending the braking ramp (P1121) ¾ Activating the compound brake (P1236) or dynamic brake (P1230) MICROMASTER 440 Operating Instructions 216 6SE6400-5AW00-0BP0 Issue 10/06 3 Functions NOTE ¾ If the DC link voltage exceeds the power-on threshold r1242 (switch-on level of Vdc_max.) of the Vdc_max controller in the "Ready" state, then the Vdc_max controller is de-activated and warning A0910 is output.

Remedy: Refer to parameters P1254 and P0210. ¾ If, in the "Run" state, the DC link voltage exceeds the power-on threshold r1242 and if the Vdc_max controller output is limited by parameter P1253 for approx. 200 ms, then the Vdc_max controller is de-activated and warning A0910 and, where relevant, fault F0002 are output.

Line supply failures are buffered using the kinetic energy (i.e. moments of inertia) of the driven load. In this case the prerequisite is that the driven load has a sufficiently high flywheel mass or is rotating at an appropriately high speed – i.e. has adequate kinetic or rotating energy. 1 1 2 2 Kinetische Energie : W = mv Rotationsenergie : W = Jω kin rot 2 2 Using this technique, the frequency is controlled (closed-loop), so that energy is fed to the drive inverter from the regenerating motor thus covering the system losses. The losses during the line supply failure still remain which means that the motor speed decreases. When using kinetic buffering it has to be taken into consideration that the motor speed reduces.

Typical applications include, for Drive example, pulley belts, flat belts or shaft chains, or pulleys for toothed wheels Deflection of drive-in and drive-out shafts which roll then transmit circumferential velocities and circumferential forces Fig. 3-87 Shaft drive with flat belts (refer to Fig. 3-87). The load torque monitoring function can then detect whether the driven load is locked or the force transmission has been interrupted. For the load torque monitoring function, the actual frequency/torque characteristic is compared with the programmed frequency/torque characteristic (refer to P2182 – P2190). If the actual value lies outside the programmed tolerance bandwidth, then, depending on parameter P2181, either warning A0952 or fault F0452 is generated. Parameter P2192 can be used to delay the output of the warning or fault message. This avoids erroneous alarms which could be caused by brief transient states (refer to Fig. 3-88).

The bandwidth is determined by the frequency values P2182 – P2184 and the torque limits P2186 – P2189.

In order to define the position of the tolerance bandwidth, different characteristics must be determined as a function of the required load torque monitoring (P2181). A differentiation can be made between the following cases: a) P181 = 1 / 4 Load torque monitoring to detect a broken belt, i.e. under fault conditions, the actual load torque is below the permissible tolerance bandwidth. In this case, the load torque characteristic with minimum permissible load should be determined.

This means that when a fault occurs, the load torque is either above or below the permissible tolerance bandwidth. In this case, the load torque characteristic with the minimum and maximum permissible load should be determined.

The permissible load torque characteristic must be determined in the operating range of the plant or system. This characteristic can be determined as follows: a) Theoretical determination In this case, the prerequisite is that the load torque characteristic in the operating range must first be known. Frequently, this is not the case in practice. Especially changing mechanical effects involve investigations that require considerable time and costs if they are to be forecast in advance. b) Practical determination The load torque characteristic is directly determined at the plant/system using a "teach-in technique". In this case, the operating range is passed- through step-by-step and the value pair comprising the actual output frequency r0021 and actual torque r0031 are read-out in the steady-state condition. If necessary, this should be carried-out for both directions of rotation. 3. The position of the tolerance bandwidth (P2182 - P2190) is determined by defining the 3 points along the characteristic. 4. In order to prevent the torque monitoring responding unnecessarily, dynamic states should be suppressed using delay time P2192. As a rule of thumb, P2192 should be > P1120. Note ¾ The load torque monitoring is active in all 4 quadrants ¾ If it is not possible to determine the min. or max. load torque characteristic at the drive in operation, then the load torque characteristic should be determined for operation at rated load. By taking into account the tolerances, the max. or min. permissible load characteristic can be calculated (e.g. the max. load characteristic is obtained from the 120% rated load characteristic). ¾ If only a specific frequency range is to be monitored, then it is sufficient to plot the load characteristic between the frequency thresholds of the envelope curve (P2182, P2184). ¾ If the drive is only permitted to have one direction of rotation, then the load characteristic should only be determined for the permissible direction of rotation. ¾ The load characteristic and/or envelope curve determined should be represented in a frequency-torque diagram, e.g. using Microsoft Excel.

There are numerous possibilities of effectively protecting the motor but at the same time ensuring high motor utilization. The basic philosophy of this innovative concept is to detect critical thermal states, output warnings and initiate the appropriate responses. By responding to critical states it is possible to operate the drive at the thermal power limit and to avoid, under all circumstances, an immediate shutdown (where the drive inverter is tripped). Features The protective concept (refer to Fig. 3-93) distinguishes itself as a result of the following individual features: ¾ Protection is effective without using any temperature sensor (P0601 = 0). The temperatures of various locations in the motor are indirectly determined using a temperature model. ¾ It is possible to evaluate temperature sensors. This has the advantage that after a line supply failure, precise initial temperatures are immediately available. Both PTC sensors (P0601 = 1) as well as KTY84 sensors (P0601 = 2) can be connected and evaluated (refer to Section 3.21.2). ¾ When using a KTY84 sensor, the drive inverter can be parameterized so that a sensor wire breakage or short-circuit F0015 is detected and the system automatically changes-over to the temperature model. This means that the drive inverter is not shut down (tripped) and operation can continue. ¾ Selectable temperature warning thresholds P0604 (default: 130 °C) for operation with the temperature model or KTY84 sensor. The drive inverter is shut down or the current reduced depending on P0610 for a value of P0604 +10%. ¾ Selectable responses P0610 which are to be initiated when the warning threshold is exceeded in order to prevent an overload condition. ¾ The motor protection has been designed to be completely independent of the drive inverter protection. Warning thresholds and responses for drive inverter protection must be separately parameterized. ¾ Various data sets are taken into account in the model. The model is separately calculated for each data set so that when changing-over between various motors the cooling of the presently non-active (fed) motors are taken into account.

Different temperature limits apply for the various materials used in electric motors.

This data permits reliable, stable operation for standard Siemens motors. If required, parameter changes must be made for motors from third-party manufacturers. We always recommend that an automatic motor data identification run is made after quick commissioning so that the electrical equivalent circuit diagram data can be determined. This allows a more precise calculation of the losses which occur in the motor which has a positive impact on the accuracy of the thermal motor model. Example: A stator resistance, which is parameterized to be too high, would result, in the model, to higher losses than in a real motor and an excessively high calculated motor temperature would be displayed. If changes are required in order to optimize the thermal model, then as a first step, the motor weight (P0344) should be checked for plausibility. Generally, the motor weight is taken from the Catalog data of the motor manufacturer. The thermal model can be further optimized by adapting the standard overtemperatures for the stator iron P0626, the stator winding P0627 and the rotor P0628. The standard overtemperatures represent the steady-state temperatures to be expected in rated operation with respect to the environment and are used to estimate the thermal resistances. Generally, these overtemperatures are not listed in the Catalog. The ambient temperature P0625 is another important parameter which influences the precision of the thermal model. NOTE ¾ In addition to the thermal motor protection, the motor temperature is also included in the adaptation of the motor equivalent circuit diagram data. This adaptation has a significant influence on the degree of stability of the closed- loop vector control – especially for a high thermal motor load. ¾ When switching-in the line supply voltage (i.e. powering-up), depending on whether a KTY sensor is being used or not, the motor temperature model is either initialized with the ambient temperature P0625 – saved in the frequency inverter – or with the actual motor temperature. ¾ If the frequency inverter is continually supplied with an external 24 V voltage, then the motor temperature is tracked/corrected using the motor temperature time constant – even when the line supply voltage is shutdown (powered-down). ¾ For closed-loop vector control, a high thermal motor load and if the line supply voltage is frequently switched-out/switched-in, then the following is required ♦ a KTY84 sensor should be used, or ♦ an external 24 V power supply should be connected MICROMASTER 440 Operating Instructions 6SE6400-5AW00-0BP0 229 3 Functions Issue 10/06 3.21.2 Temperature sensor When the motor is operated below the 5 V rated speed the cooling effect of the shaft-mounted fan is reduced. As a 574 Ω result, for most motors when continually operated at lower frequencies, the Kl. 14 power has to be reduced. Under these A PTC/ conditions, motor protection against KTY D overheating can only be guaranteed if either a temperature sensor (PTC or Kl. 15 KTY84 sensor) is integrated in the motor and is connected to the control terminals 14 and 15 of the MICROMASTER 440 (refer to Fig. 3-94) Fig. 3-94 Connecting a temperature or the motor temperature model was sensor to MICROMASTER determined (refer to Section 3.21.1). NOTE In order to avoid EMC noise from being coupled-in to the drive converter electronics – and the associated disturbances – it is not permissible to use free conductors in the motor cable to connect the temperature sensor to the drive converter. The temperature sensor must be connected to the drive converter using a separate cable (if at all possible, this cable should be shielded). MICROMASTER 440 Operating Instructions 230 6SE6400-5AW00-0BP0 Issue 10/06 3 Functions With PTC temperature sensor (P0601 = 1) The PTC is connected to the control terminals 14 and 15 of the MICROMASTER 440. PTC monitoring is activated with the parameter setting P0601 = 1. If the resistance value, connected at the terminals, is less than 1500 Ω, then neither alarm nor fault is generated. If this value is exceeded, the drive inverter outputs alarm A0511 and fault F0011. The resistance value where the alarm and fault are output does not lie below 1000 Ω and not above 2000 Ω. Response thresholds: 4.0 V 0 → 1 3.8 V 1 → 0 Fig. 3-95 PTC characteristic for 1LG / 1LA motors With KTY84 temperature sensor (P0601 = 2) The KTY84 must be connected so that the diode is in the conductive direction. This means that the anode is connected to terminal 14 and the cathode to terminal 15. If the temperature monitoring function is activated with the setting P0601 = 2, the temperature of the sensor (i.e. of the motor windings) is written into parameter r0035 (refer toFig. 3-93). The threshold temperature ϑ (refer to Table 3-36) of the trip motor can now be set using the warning threshold, motor overtemperature ϑ warn (parameter P0604) (the factory setting is 130 °C). The following applies: ϑ trip P0604 = ϑ = warn Fig. 3-96 KTY84 characteristic for 1.1 1LG / 1LA motors Wire breakage or short-circuit If the circuit between the drive inverter and PTC or KTY84 sensor is interrupted or there is a short-circuit, the drive inverter is shut down (tripped) and fault F0015 is displayed.

This protection concept is also sub-divided into 2 levels: ¾ Warning and response ¾ Fault and shutdown Using this concept, a high utilization of the power module components can be achieved without the drive inverter being immediately shut down. The power module components are monitored as follows: Table 3-37 General protection of the power components Warning and response Fault and shutdown Overcurrent / short circuit Imax controller for V/f F0001 A0501 r0056 bit 09 r0056 bit 13 (refer to Section 3.23.1.2) Current controller for SLVC / VC --- r0056 bit 09 r1407 bit 08 r1407 bit 09 DC link overvoltage Vdc_max controller F0002 A0502 (refer to Section 3.18.1) DC link undervoltage Vdc_min controller F0003 A0503 (refer to Section ) Line phase failure detection --- F0020 (refer to P0291) The monitoring thresholds for the righthand column in the table above are permanently saved in the drive inverter and cannot be changed by the user. On the other hand, the threshold levels for the "Warning and response" column can be modified by the user to optimize the system. These values have default settings so that the "Fault and shutdown" thresholds do not respond. MICROMASTER 440 Operating Instructions 232 6SE6400-5AW00-0BP0 Issue 10/06 3 Functions 3.22.2 Thermal monitoring functions and overload responses Parameter range: P0290 – P0294 r0036 – r0037 Warnings A0504, A0505 Faults F0004, F0005, F0012, F0020, F0022 Function chart number: - Similar to motor protection, the main function of the thermal power module monitoring is to detect critical states. Parameterizable responses are provided to the user which allows the drive system to be still operated at the power limit thus avoiding immediate shutdown. However, the possibilities of assigning parameters only involves interventions below the shutdown threshold which cannot be changed by users. MICROMASTER 440 has the following thermal monitoring functions: 2 ¾ i t monitoring 2 The i t monitoring is used to protect components which have a long thermal time constant in comparison to the semiconductors. An overload with reference 2 to i t is present if the drive inverter utilization r0036 indicates a value greater than 100 % (utilization as a % referred to rated operation). ¾ Heatsink temperature The monitoring of the heatsink temperature r0037[0] of the power semiconductor (IGBT). ¾ Chip temperature Significant temperature differences can occur between the barrier junction of the IGBT and the heatsink. These differences are taken into account by the chip temperature r0037[1] and monitored. When an overload occurs regarding one of these three monitoring functions, 2 initially, a warning is output. The warning threshold P0294 (i t monitoring) and P0292 (heatsink temperature and chip temperature monitoring) can be parameterized relative to the shutdown values. Example The warning threshold P0292 for the temperature monitoring (chip / heatsink temperature) is set to 15 °C in the factory. This means that warning A0504 is output 15 °C below the shutdown threshold. At the same time that the warning is output, the parameterized responses are initiated via P0290. Possible responses include: ¾ Reducing the pulse frequency (P0290 = 2, 3) This is an extremely effective method to reduce losses in the power module, as the switching losses represent a very high proportion of the overall losses. In many applications, a temporary reduction of the pulse frequency can be tolerated in favor of maintaining the process. MICROMASTER 440 Operating Instructions 6SE6400-5AW00-0BP0 233 3 Functions Issue 10/06 Disadvantage The current ripple is increased when the pulse frequency is reduced. This can result in an increase of the torque ripple at the motor shaft (for low moments of inertia) and an increase in the noise level. When the pulse frequency is reduced this has no influence on the dynamic response of the current control loop as the current control sampling time remains constant ! ¾ Reducing the output frequency (P0290 = 0,2) This is advantageous if it is not desirable to reduce the pulse frequency or if the pulse frequency is already set to the lowest level. Further, the load should have a characteristic similar to that of a fan, i.e. a square-law torque characteristic for decreasing speed. When the output frequency is reduced, this significantly reduces the drive inverter output current and in turn reduces the losses in the power module. ¾ No reduction (P0290 = 1) This option should be selected if neither a reduction in the pulse frequency nor a reduction in the output current is being considered. In this case, the drive inverter does not change its operating point after the warning threshold has been exceeded so that the drive can be further operated until the shutdown values are reached. After the shutdown threshold has been reached, the drive inverter shuts down (trips) with fault F0004. The time which expires up to shutdown is however not defined and depends on the magnitude of the overload. Only the warning threshold can be changed in order to obtain an earlier warning and, if required, externally intervene in the drive process (e.g. by reducing the load, lowering the ambient temperature). NOTE ¾ If the drive inverter fan fails, this would be indirectly detected by the measurement of the heatsink temperature. ¾ A wire breakage or short circuit of the temperature sensor(s) is also monitored. MICROMASTER 440 Operating Instructions 234 6SE6400-5AW00-0BP0 Issue 10/06 3 Functions 3.23 Open-loop/closed-loop control technique There are several open-loop/closed-loop techniques for closed-loop speed and torque control for drive inverters with induction and synchronous motors. These techniques can be roughly classified as follows: ¾ V/f characteristic control (briefly: V/f control) ¾ Field-orientated closed-loop control technique (briefly: Vector control) The field-orientated control technique – also known as Vector control – can be further sub-divided into two groups: ¾ Vector control without speed feedback (sensorless Vector control (SLVC)) ¾ Vector control with speed feedback (Vector control (VC)) These techniques differ from one another both regarding the control quantity as also in the complexity of the technique, which in turn are obtained as a result of the requirements associated with the particular application. For basic applications (e.g. pumps and fans), to a large extent, V/f control is used. Vector control is mainly used for sophisticated applications (e.g. winders), where a good control and behavior in noisy conditions are required regarding the speed and torque. If these requirements are also present in the range from 0 to approx. 1 Hz, then the speed/torque accuracy without encoder is not sufficient. In this case, Vector control with speed feedback must be used. 3.23.1 V/f control Parameter range: P1300 P1310 – P1350 Warnings - Faults - Function chart number: FP6100 The V/f characteristic represents the simplest control technique. In this case the stator voltage of the induction motor or synchronous motor is controlled proportionally to the stator frequency. This technique has proven itself for a wide range of "basic" applications, such as ¾ Pumps, fans ¾ Belt drives and similar processes. The goal of V/f control is to keep the flux Φ constant in the motor. In this case, this is proportional to the magnetizing current I and the ratio between voltage V and µ frequency f. Φ ~ I ~ V/f µ The torque M, developed by induction motors, is proportional to the product Φ x I) of flux and current. (precisely the Vectorial product M ~ Φ ∗ I In order to generate the highest possible torque from a given current, the motor must operate with a constant flux which is as high as possible. In order to keep the flux Φ constant, when frequency f changes, the voltage V must be changed in proportion so that a constant magnetizing current I flows. The V/f characteristic µ control is derived from these basic principles.

Even at low frequencies, the ohmic resistances of the stator winding play a role, which are neglected when determining the motor flux in Section 3.23.1. This means that the output voltage can be too low in order to ¾ implement the magnetization of an induction motor, ¾ to hold the load ¾ to compensate voltage drops (ohmic losses in the winding resistances) in the system or ¾ to provide a breakaway / accelerating / braking torque. The output voltage can be increased (boosted) in MICROMASTER using the following parameters (refer to Table 3-39): MICROMASTER 440 Operating Instructions 6SE6400-5AW00-0BP0 237 3 Functions Issue 10/06 Table 3-39 Voltage boost Parameter Voltage boost Explanation P1310 Constant The voltage boost is effective over the complete voltage boost frequency range whereby the value continually decreases at high frequencies.

These resonance effects result in an increased noise level and also can damage / destroy the mechanical system. These resonance effects can occur for: ¾ Geared motors ¾ Reluctance motors ¾ Large motors (low stator resistance → poor electrical damping) Contrary to the "skip frequency" function (refer to Section 3.12.1 and parameters P1091 to P1094), where the resonance frequency is passed through as quickly as possible, for the V/f resonance damping (parameter P1338), the resonance effects are dampened from a control-related perspective. The advantage of this function is that by using this active damping, operation is possible in the resonance range. The V/f resonance damping is activated and adjusted using parameter P1338. This parameter represents a gain factor that is a measure for the damping of the resonance frequency. The following oscillogram indicates the effect of the resonance damping function using as an example a reluctance motor with gearbox. The phase output currents are displayed for an output frequency of 45 Hz.

This permits the output current to be precisely determined referred to the motor voltage. This measurement guarantees that the output current is sub-divided into a load component and a flux component. Using this sub-division, the motor flux can be controlled and can be appropriately adapted and optimized i in-line with the prevailing conditions. flux FCC operation is only activated after the FCC starting frequency P1333 has been exceeded. The FCC starting frequency P1333 is entered as a percentage to the rated motor frequency P0310. For a rated motor frequency of 50 Hz and a factory setting of P1333 = 10 %, this results in an FCC starting frequency of 5 Hz. The FCC starting frequency may not be selected too low as this has a negative impact on the control characteristics and can result in oscillation and system instability. The "V/f with FCC" control type (P1300 = 1) has proven itself in many applications. It has the following advantages with respect to the standard V/f control: ¾ Higher motor efficiency ¾ Improved stabilizing characteristics ♦ → higher dynamic response ♦ → improved behavior to disturbances / control NOTE Contrary to closed-loop vector control with / without speed encoder (VC / SLVC), for the V/f open-loop control mode with FCC, it is not possible to specifically influence the motor torque. This is the reason that it isn’t always possible to avoid the motor stalling – even when using "V/f with FCC". An improvement in the stabilizing behavior and in the motor efficiency can be expected when using the closed-loop vector control with / without speed encoder when compared to V/f control with FCC.

This controller protects the drive inverter and the motor against continuous overload by automatically reducing the drive inverter output frequency by f (r1343) or the Imax drive converter output voltage by V (r1344). By either reducing the frequency or Imax voltage, the stressing on the drive inverter is reduced and it is protected against continuous overload and damage.

The Vector control principle is based on the fact that for a specific load situation or required torque, the required motor current is impressed with respect to the motor flux so that the appropriate torque is obtained. If the stator current is emulated in a circulating coordinate system, linked with the rotor flux Φ, then it can be broken-down into flux-generating current component i in-line with the rotor flux and in a torque-generating current d component i , vertical to the rotor flux. These components are corrected to track q their setpoints in the current controller using their own dedicated PI controllers and are equal quantities in steady-state operation.

The Vector control can be used both with and without speed encoder. MICROMASTER 440 Operating Instructions 6SE6400-5AW00-0BP0 243 3 Functions Issue 10/06 The following criteria provide a basis as to when a speed actual value encoder is required: ¾ High speed accuracy is required ¾ High requirements are placed on the dynamic response ♦ Improved control performance ♦ Improved immunity to disturbances ¾ The torque is to be controlled over a control range greater than 1:10 ¾ A defined and/or a changing torque has to be maintained for speeds below approx. 10 % of the rated motor frequency P0310 When it comes to entering a setpoint, the Vector control (refer to Table 3-40) is sub-divided into ¾ Closed-loop speed control, and ¾ Closed-loop torque/current control (briefly: Closed-loop torque control). Table 3-40 Vector control versions Vector control (closed-loop) Without encoder With encoder Closed-loop speed control P1300 = 20, P1501 = 0 P1300 = 21, P1501 = 0 Closed-loop torque control P1300 = 20, P1501 = 1 P1300 = 21, P1501 = 1 P1300 = 22 P1300 = 23 When closed-loop speed control is used, the closed-loop torque control is secondary. This type of cascaded closed-loop control has proven itself in practice regarding commissioning and increased transparency.

In this case, the model is supported by the accessible currents and voltages. At low frequencies (≈ 0 Hz), the model is not able to determine the speed. This is the reason and also due to uncertainty in the model parameters and measuring inaccuracy, that a changeover is made from closed-loop to open-loop controlled operation in this range. The changeover between closed-loop controlled / open-loop controlled operation is controlled using the time and frequency conditions (P1755, P1756, P1758) (refer to Fig. 3-102). The system does not wait for the time condition if the setpoint frequency at the ramp-function generator input and the actual frequency simultaneously lie below P1756. £ f_act£ P1755 P1756 [Hz] t SLVC open loop SLVC closed loop t P1758 P1756 [%] P1756 [Hz] = P1755 [Hz] ⋅ 100 [%] Fig. 3-102 Changeover condition for SLVC In the open-loop controlled mode, the speed actual value is the same as the setpoint. For suspended loads or when accelerating, parameter P1610 (constant torque boost) and P1611 (torque boost when accelerating) must be modified in order to allow the drive to provide the steady-state and/or dynamic load torque. If P1610 is set to 0 %, then only the magnetizing current r0331 is impressed for a value of 100 % of the rated motor current P0305. In order that the drive does not stall when accelerating, P1611 can be increased or the acceleration pre-control can be used for the speed controller (refer to Section 3.23.2.3). This is also practical in order that the motor is not thermally overloaded at low speeds. For Vector control without speed actual value encoder MICROMASTER 440 has, in the low frequency range, the following outstanding features with respect to other AC drive inverters: MICROMASTER 440 Operating Instructions 6SE6400-5AW00-0BP0 245 3 Functions Issue 10/06 ¾ Closed-loop controlled operation down to ≈ 1 Hz ¾ Can start in the closed-loop controlled mode (immediately after the drive has been energized) ¾ The low frequency range (0 Hz) is passed-through in closed-loop controlled operation Start Zero crossing f f Closed loop Closed loop P1755 P1755 Open loop Open loop t t P1755 Fig. 3-103 Starting and passing-through 0 Hz in closed-loop controlled operation The following advantages are obtained as a result of closed-loop controlled operation down to approx. 1 Hz (this can be selected using parameter P1755) as well as also the possibility to immediately start closed-loop controlled at 0 Hz or to reverse closed-loop controlled (this can be set using parameter P1750): ¾ No changeover operation is required within the closed-loop control (smooth behavior – no frequency dips) ¾ Continuous closed-loop speed-torque control is possible down to approx. 1 Hz. NOTE For closed-loop controlled reversing or closed-loop controlled starting from 0 Hz it must be taken into account that when staying too long (> 2 s or > P1758) in the range around 0 Hz, that the closed-loop control automatically changes-over from closed-loop into the open-loop controlled mode.

Speed controller (SLVC: P1470, P1472, P1452 VC: P1460, P1462, P1442) The speed controller (refer to Fig. 3-105) receives its setpoint r0062 from the setpoint channel (refer to Section 3.12), the actual value r0063 either directly from the speed actual value encoder or, for VC, also directly through the motor model for SLVC. The system error is amplified by the PI controller and, together with the pre-control, forms the torque setpoint. For increasing load torques, when the droop function is active, the speed setpoint is proportionally reduced so that the load on an individual drive within a group (where two or several motors are mechanically coupled) is reduced when excessively high torques occur.

The controller parameters are defined according to the symmetrical optimum as follows: T = 4 T n σ * K = ½ r0345 / T = 2 r0345 / T p * σ * n T = sum of the low delay times σ If oscillations occur with these particular settings, then the speed controller gain K p should be manually reduced. It is also possible to increase the speed actual value smoothing (this is the usual procedure for gearbox play or high-frequency torsional oscillations) and then re-call the controller calculation as the value is incorporated in the computation of K and T . p n The following interrelationships apply for the optimization routine: ¾ If K is increased then the controller becomes faster and the overshoot is p reduced. However, the signal ripple and oscillations in the speed controller loop are increased. ¾ If T is reduced, then the controller also becomes faster. However, the n overshoot increases. When manually adjusting the speed control, the simplest procedure is to initially define the possible dynamic response using K (and the speed actual value p smoothing) in order to then reduce the integral action time as far as possible. In this case it is important to ensure that the closed-loop control must also remain stable in the field-weakening range. When oscillations occur in the closed-loop speed control, it is generally sufficient to increase the smoothing time in P1452 for SLVC or P1442 for VC (or to reduce the controller gain) in order to dampen oscillations. The integral output of the speed controller can be monitored using r1482 and the unlimited controller output can be monitored using r1508 (torque setpoint). NOTE When compared to closed-loop control with encoder (refer to Section 3.23.2.2), the dynamic response for sensorless drives is significantly reduced. This is because the speed can only be derived from the drive inverter output quantities for current and voltage which have the appropriate noise level. MICROMASTER 440 Operating Instructions 6SE6400-5AW00-0BP0 249 3 Functions Issue 10/06 Speed controller pre-control (P1496, P0341, P0342) The control behavior of the speed control loop can be improved if the speed controller of the drive inverter also generates values for the current setpoints (corresponds to the torque setpoint) from the speed setpoint. This torque setpoint dn dn m , which is calculated as follows v mv = P1496 ⋅Θ ⋅ = P1496 ⋅P0341⋅P0342 ⋅ dt dt is entered into the current controller through an adaptation element directly as additive control quantity (this is enabled using P1496). The motor moment of inertia P0341 is directly calculated during the quick commissioning (refer to Section 3.5.8) or the complete parameterization (P0340 = 1, refer to Section 3.5.4). The factor P0342 between the total moment of inertia and motor moment of inertia must be manually determined.

On the other hand, speed setpoint changes bypass the speed controller and are therefore executed faster. The effect of the pre-control quantity can be adapted, depending on the particular application, using the pre-control factor P1496. Using P1496 = 100 %, the pre- control is calculated according to the motor and load moment of inertia (P0341, P0342). In order that the speed controller does not work against the torque setpoint which is entered, a balancing filter is automatically used. The time constant of the balancing filter corresponds to the equivalent delay time of the speed control loop. The speed controller pre-control is correctly set (P1496 = 100 %, calibration via P0342), if the I component of the speed controller (r1482) does not change during a ramp-up or ramp-down in the range n > 20% * P0310. This means, using the pre- control, it is possible to approach a new speed setpoint without overshoot (prerequisite: The torque limiting does not intervene and the moment of inertia remains constant). MICROMASTER 440 Operating Instructions 250 6SE6400-5AW00-0BP0 Issue 10/06 3 Functions If the speed controller is pre-controlled, then the speed setpoint (r0062) is delayed with the same smoothing (P1442 or P1452) as the actual value (r1445). This ensures that when accelerating, there is no setpoint – actual value difference (r0064) at the controller input which would have been exclusively caused by the signal propagation time. When the speed pre-control is activated, it must be ensured that the speed setpoint is continuously entered and without any significant noise level (avoid torque surges). An appropriate signal can be generated by smoothing the analog signal P0753 (refer to Section 3.6.3) or by activating the rounding-off function of the ramp- function generator P1130 – P1133 (refer to Section 3.12.2). NOTE ¾ The ramp-up and ramp-down times (P1120; P1121) of the ramp-function generator (refer to Section 3.12.2) in the setpoint channel should only be set so fast that when accelerating and braking, the motor speed can follow the setpoint. This then guarantees the optimum functioning of the speed controller pre-control. ¾ The starting time r0345 is a measure for the overall moment of inertia of the machine and describes that time in which the unloaded drive can accelerate from standstill to the rated motor speed P0311 with the rated motor torque r0333. 2⋅ π⋅n 2⋅ π⋅P0311 Mot,rated r0345 = Tstarting = Θ ⋅ = P0341⋅P0342 ⋅ 60 ⋅M 60 ⋅r0333 Mot,rated If these secondary conditions match the particular application, then the starting time can be used as the shortest value for the ramp-up and ramp-down times.

However, this load sharing control can only be used if the drives only motor and are operated more or less under steady-state conditions (i.e. at constant speed). For drives, which are frequently accelerated and braked with high speed changes, this technique is only conditionally suitable. The most simple load sharing control is, e.g., used for applications where two or several motors are mechanically coupled or operate on a common shaft and which have to fulfill the requirements above. In this case, the droop controls torsional stressing associated with the mechanical coupling by changing the speeds of the individual motors (excessive torques are reduced for an individual drive). Prerequisite ¾ All of the drives must be operated with closed-loop Vector speed control (with or without speed actual value encoder) ¾ The ramp-up and ramp-down times of the ramp-function generator must be identical for all of the drives. MICROMASTER 440 Operating Instructions 252 6SE6400-5AW00-0BP0 1 Issue 10/06 3 Functions 3.23.2.4 Closed-loop torque control Parameter range: P1300, P1500 – P1511 P1400 – P1780 Warnings - Faults - Function chart number: FP7200, FP7210, FP7700, FP7710 For sensorless closed-loop speed control SLVC (P1300 = 20) or for closed-loop speed control with sensor VC (P1300 = 21), it is possible to changeover to closed- loop torque control (slave drive) using BICO parameter P1501. It is not possible to changeover between closed-loop speed and torque control if the closed-loop torque control is directly selected using P1300 = 22 or 23. The torque setpoint and supplementary torque setpoint can be selected using parameter P1500 and also using BICO parameter P1503 (CI: Torque setpoint) or P1511 (CI: Supplementary torque setpoint). The supplementary torque acts both for the closed-loop torque control as well as for the closed-loop speed control (refer to Fig. 3-108). As a result of this feature, a pre-control torque for the speed control can be implemented using the supplementary torque setpoint. NOTE For safety reasons, it is presently not possible to assign fixed torque setpoints.

Above the maximum speed (plus 3 %), a speed limiting controller reduces the torque limits in order to prevent the drive accelerating any further. A "real" closed-loop torque control (with automatically set speed) is only possible in the closed-loop controlled range but not in the open-loop controlled range. In the open-loop controlled range, the torque setpoint changes the setpoint speed through a ramp-up integrator (integration time ~ P1499 P0341 P0342). This is * * the reason that sensorless closed-loop torque control in the area around standstill (0 speed) is only suitable for applications which require an accelerating torque there and not a load torque (e.g. traversing drives). For closed-loop torque control with sensors, this restriction does not apply. If the closed-loop torque control is active, and a fast stop command (OFF3) is output, then the system automatically changes-over to closed-loop speed control and the drive is braked. If a normal stop command (OFF1) is output, there is no changeover. Instead, the system waits until a higher-level control has brought the drive to a standstill, in order to inhibit the pulses there. This is necessary in order to allow the master and slave drives to be shut down together. For P1300 = 22 or 23, for OFF1, the drive is directly powered-down (as for OFF2). 3.23.2.5 Limiting the torque setpoint Parameter range: P1520 – P1531 P0640, r0067 r1407 bit 08, r1407 bit 09 Warnings - Faults - Function chart number: FP7700, FP7710 All of the following limits act on the torque setpoint which is either entered at the speed controller output for closed-loop speed control or as torque input for closed- loop torque control.

This minimum is cyclically computed in the drive inverter and displayed in parameters r1538, r1539. ¾ r1538 Upper torque limit ¾ r1539 Lower torque limit This means that these cyclic values limit the torque setpoint at the speed controller output / torque input and indicate the instantaneously maximum possible torque.

There are three routes for the manufacturer/assembler to demonstrate compliance: 7.1.1 Self-certification This is a manufacturer's declaration that the European standards applicable to the electrical environment for which the apparatus is intended have been met. Only standards that have been officially published in the Official Journal of the European Community can be cited in the manufacturer's declaration. 7.1.2 Technical construction file A technical construction file can be prepared for the apparatus describing its EMC characteristics. This file must be approved by a ‘Competent Body’ appointed by the appropriate European government organization. This approach allows the use of standards that are still in preparation. 7.1.3 EC type examination certificate This approach is only applicable to radio communication transmitting apparatus. All MICROMASTER 440 units are certified for compliance with the EMC directive. when installed in accordance with the recommendations in Section 2. MICROMASTER 440 Operating Instructions 276 6SE6400-5AW00-0BP0 Issue 10/06 7 Electro-magnetic compatibility 7.1.4 EMC Directive Compliance with Imminent Harmonics Regulations From 1st January 2001 all electrical apparatus covered by the EMC Directive will have to comply with EN 61000-3-2 "Limits for harmonic current emissions (equipment input ≤ 16 A per phase)".

MICROMASTER 440 Operating Instructions 6SE6400-5AW00-0BP0 299 Short circuit current rating (SCCR) Issue 10/06 F Short circuit current rating (SCCR) Frame Sizes A to C The equipment has a "standard SCCR" value of 10 kA, which complies with the requirements of UL508C. In addition to the "standard SCCR" a "high SCCR" is available which can be used for industrial control panel installations in line with the National Electrical Code (NEC) article 409 (edition 2005) and Underwriters Laboratories UL508A (effective April 2006). The uL certification of MICROMASTER 440 allows the drives to adopt a high SCCR equal to the interupt current rating of the branch-circuit protection (BCP) device protecting the drive. Hence by selection of the correct uL listed BCP device with appropriate interrupt rating for the application, any high SCCR rating can be achieved for MICROMASTER 440, including SCCR values above 10 kA. The above statements are valid for the respective maximum voltage of the drive when protected by a UL recognised/listed H, J or K type fuse, a circuit breaker or self-protected combination motor controller. Frame Sizes D to GX The equipment has a "standard SCCR" value of 42 kA, which complies with the requirements of UL508C. A "high SCCR", which can be used for industrial control panel installations in line with the National Electrical Code (NEC) article 409 (edition 2005) and Underwriters Laboratories UL508A (effective April 2006), can be achieved with the use of current limiting fuses or circuit breakers with an appropriate interrupt rating and derived let through current. For compliance with NEC article 409 and UL508A the calculation, selection and marking of the current limiting device must be carried out by an qualified engineer. The above statements are valid for the respective maximum voltage of the drive when protected by a UL recognised/listed H, J or K type fuse, a circuit breaker or self-protected combination motor controller MICROMASTER 440 Operating Instructions 300 6SE6400-5AW00-0BP0 Issue 10/06 Standards G Standards European Low Voltage Directive The MICROMASTER product range complies with the requirements of the Low Voltage Directive 73/23/EEC as amended by Directive 98/68/EEC.
