Several drives can be mounted to a single supply module. Supply module KVR 1.3, with its regeneration capability, is a component of the INDRAMAT modular AC drive system. Supply module KVR 1 provides the link circuit d.c. voltage for the power supply and the control voltage for all connected INDRAMAT main and servo- drive modules. • DOK-POWER*-KVR*1.3****-ANW1-EN-E1,44 • 10.96 7 1. Installing the Modular INDRAMAT AC Drive System 1.1. Main functions of supply module KVR 1 The power rectifier of the KVR rectifies the threephase mains alternating Power supply of the voltage and provides a regulated link circuit d.c. voltage for the drives power drives supply. The KVR 1 operates as an inverter in the event the drives are generator-driven, and feeds the power back into the mains. Buffer capacitors provide sufficient smoothing. In the event of a power failure, or, if the power supply should be switched off, then the energy regenerated as a result of the braking of the motors will be assimilated by the bleeder resistor in the KVR 1. The KVR1’s internal power contactor makes it possible to isolate the drives from the mains. The KVR supplies the drive module’s electronics via the signal voltage bus. In Supply to the the event of a mains failure, the signal voltages will receive power from the electronics d.c. link circuit. As a result, the drive electronics remain operational when the drives are in generator mode. The KVR has been equipped with extensive monitoring functions. These Drive monitoring communicate with the drive modules via the signal voltage bus. system The Bb1 contact of the KVR is very important for the drive system operation.

Area of application 2.5. Functional power features • It is possible to operate the drives for long periods even while braking The energy created by braking the motor is fed back into the mains with little loss of power. • Direct mains connection The KVR can be directly connected to 3 x AC 380...480V, 50...60 Hz mains without the use of a transformer. • Power shutdown with the use of internal contactors The contactor which shuts down the drive’s power supply is a component of the KVR1. • Internal link circuit short-circuit Internal link circuit short-circuits have the ability to brake synchronous motors in the event of a problem in the electronics of the motor. • High overload capability Peak power of 90 kW to accelerate motors. • Loss of heat due to energy in the control cabinet The heatsink is located outside the control cabinet. This makes compact control cabinets possible. • Fuse protection is possible with circuit breakers – Expensive semi-conductor fuses are not needed. – No special fuses for exports. • The drive systems reaction to a power failure can be programmed by adding an external link. – Without the links, the motors brake at maximum torque. – With the links, there is a signal to the NC control via a voltageless contact. Thus, the shutdown of the motors can be guided by the NC. Expensive tools or workpieces are protected against damage. • Controlled bridge voltage No reduction in drive response in the event of mains undervoltage. • Charging current limiting for bridge capacitors The inrush current can be ignored when selecting the switchgear for the power supply. The service life of the switchgear is increased. • High capacitance of the control voltage It is possible to connect ten drive modules to one supply module. • Service friendly – Signal lines are connected with screw terminals. – A numeric display makes extensive diagnostics and controlled elimination of faults possible. • DOK-POWER*-KVR*1.3****-ANW1-EN-E1,44 • 10.96 13 3.

Ouptut UD reports a power failure.The NC control must then initiate a position controlled shutdown of the drives within 10 ms for the drive electronics to remain functional. If it takes the drives more than 10 ms to feed energy back into the link circuit, then additional capacitors should be used to maintain power supply to the electronics. An aluminum electrolytic capacitor is recommended due to lack of space. The voltage between EPU+ and EPU- can reach DC 450V. The capacitor must be able to handle this voltage.

Electrical Connections – Installation Guidelines 3.13. Fault current protective device It is recommended that the overcurrent fuse (fuse, power circuit breaker) switch the machine off if there is a short in the housing. If an FI current limiting type circuit breaker is absolutely required in TT-mains because of the extent of the grounding resistance, then the following must be noted. The capacitive leakage currents in switch-mode drives generally flow to earth. The extent of the leakage current depends on • the number of drives used • the length of the motor power cable • the grounding conditions at the installation site The leakage current is inevitably increased, if steps are taken to improve the electromagnetic compatibility (EMC) of the machine (mains filter, shielded lines). This means that FI current limiting type circuit breakers with nominal fault currents equal to less than 0.3 A should generally not be used! False tripping can occur when inductances and capcitances are switched on (interference suppression filters, transformers, contactors, magnetic valves). Commercially available pulse current sensitive FI current limiting ~ _∩_∩ _ type circuit breakers (machine identification ) do not guarantee the protection of electronic devices with threephase link circuits (B6 circuit). The protection of electrical apparatus mounted to a pulse current sensitive FI current limiting type circuit breaker together with devices which have a B6 circuit, can be affected. Use either FI current limiting type circuit breakers which switch off with d.c. fault currents, or mount an isolation transformer into the mains supply line. If isolation transformers are used, then these should tune the overcurrent protective device to the impedance of the fault loop so that there is a powering down given a fault. Connect the star point of the secondary winding with the protective conductor of the machine. 3.14.

KVR controller 4. KVR controller The control signals of the mains contactor and the link circuit short circuit in the KVR that are suggested by INDRAMAT illustrate the operating principle. Other controller configurations are outlined in this chapter. The choice of control and its effect depends upon the range of functions and the sequence of actions of the whole plant and is the responsibility of the equipment manufacturer. 4.1. Possible fault responses A: shutdown due to Stopping the drives with or without link circuit short-circuit fault in drive In the event of a malfunction in the drive electronics, the link circuit voltage electronics is shorted as an additional safety measure to brake the drives to a standstill. With link circuit short-circuits, synchronous motors are always braked to standstill (MAC or MDD) whether or not the drive electronics are still operational. Asynchronous motors (2AD or 1MB) are not braked if link circuit voltage is short-circuited. Without link circuit short-circuit, functioning drives are braked at maximum torque. It must, however, be assumed that there will be a slowing down without electrical braking in those drives where the control electronics are disrupted or those where regeneration lines are interrupted. The link circuit short-circuit can only then be obviated, if slowing down without braking will not result in damage. As an alternative, it is possible to use motors with mechanical blocking brakes. How to best shutdown the drives in the event of a problem is, on the one hand, dependent upon the drive equipment used and, on the other, on its function. For this reason, only the designer can make this decision. The following should, therefore, only be seen as a supportive recommendation for the designer. • DOK-POWER*-KVR*1.3****-ANW1-EN-E1,44 • 10.96 32 4.

With an emergency stop or mains failure, the drives are usually stopped by the drive controller. In the case of an E-stop or if the drives´ internal monitors are activated, a zero setpoint is initiated by the drive controller and the drives are braked under control at maximum torque. In a few applications (e.g., electronically-coupled gear-cutting machines), the drives have to be stopped under control in the event of an emergency stop or mains failure. In the case of an E-stop, or if the drives` internal monitors are activated, the drives are braked under position control by the NC controller. with link circuit drives stopped if short-circuit drive electronics malfunction without link circuit short-circuit by the drive electronics controller braking during E-stop or mains by the failure NC controller Figure 4.2: Summary of fault responses • DOK-POWER*-KVR*1.3****-ANW1-EN-E1,44 • 10.96 33 4. KVR Controller 4.2. Controlling the KVR with link circuit short-circuit This control type should be selected under normal circumstances! A high degree of security is obtained with this type of control at low cost. The Application monitors built into this drive system are most effectively used. Typical application: – if KVR is supplying feed drives only –if asynchronous main and feed drives are run from one KVR 1. It is possible to brake the INDRAMAT AC drives even when power is off. It is, Features therefore, possible in an emergency to immediately shut off power. The supply module transforms the energy contained within the momentum of the drive into heat. With link circuit short-circuit, synchronous motors are always braked to standstill, whether the drive electronics are still functioning or not. The link circuit short-circuit comes into operation only during drive malfunctions. If the E-stop button is pressed, the asynchronous main drives are also braked. With an emergency stop or when the KVR´s monitors are activated (e.g., mains failure), the drives are braked at maximum torque under the control of the drive electronics. Do not close the NCB link on the KVR (X3/1 - X3/2). Mode of operation When the E-stop button is pressed, the mains contactor in the KVR 1 drops out immediately. The drives´ controller enabling signals are disconnected via an auxiliary contact of the mains contactor. This results in internal set-point zeroing of all connected drives, which then undergo controlled braking. A drive fault message via the KVR 1 (Bb1 contact), a fault message via the NC controller (servo fault), or overruning the limit switches results in the mains contactor being de-energized and the link circuit short-circuit then comes into operation. • DOK-POWER*-KVR*1.3****-ANW1-EN-E1,44 • 10.96 34 4.

Controlling the KVR 1 without link circuit short- circuit In exceptional circumstances, power disconnection is adequate to protect the system from damage when overruning the limit switch or in the event of a malfunction in the drive electronics. Typical applications: – when the KVR 1 is supplying asynchronous drives only – when the limit switch of the feed drive axis is sufficiently damped Features The INDRAMAT AC drives can still brake with power off. This means that power can usually be immediately switched off in an emergency. The energy retained in the momentum of the drive is transformed into heat in the bleeder resistor of the supply module. The link circuit short-circuit is not short-circuited. With asynchronous drives, the link circuit short-circuit has no additional braking effect during drive electronics malfunctions. If the link circuit voltage is shortened, asynchronous drives can no longer undergo controlled braking. With an emergency stop or when the KVR 1´s monitors are activated (e.g., mains failure), the drives are braked at maximum torque under the control of the drive electronics. Do not close the NCB link on the KVR (X3/1 - X3/2). Mode of operation The mains contactor in the KVR 1 drops out immediately when the emergency stop circuit is broken. The drives´ controller enabling signals are disconnected by an auxiliary contact in the mains contactor. This results in internal set-point zeroing of all connected drives, which then undergo controlled braking. If the drive electronics malfunction, the drives run out of control. Short-circuiting of the link circuit can only be dispensed with, if the system´s linear axes can run up to their mechanical fixed stop during a drive malfunction without risk of damage. It is possible, as an alternative, to use motors with mechanical blocking brakes. • DOK-POWER*-KVR*1.3****-ANW1-EN-E1,44 • 10.96 36 4.

Controlling the KVR to brake the drives under position control Application In exceptional cases! Usually in drives that are coupled via the NC controller and which must not adopt an angular error during a mains failure. Do not use an NCB link in digital drives with SERCOS interface. The programmable fault response of digital drives makes a position controlled braking without an NCB link possible. The NCB link blocks the message going to the drives that the power supply is faulty. Features The INDRAMAT AC drives can still brake when power is off. This means that power can be immediately turned off in an emergency. The energy retained in the momentum of the drive is transformed into heat in the bleeder resistor of the supply module. The link circuit voltage is not short-circuited, so energy is available for stopping the drives under position control. With an emergency stop or when the KVR´s monitors are activated (e.g, mains failure), the drives are braked by the NC controller under position control. The energy stored or regenerated in the link circuit must exceed that required for exciting asynchronous drives or for return motion. The NCB link on the KVR (X3/1 - X3/2 ) must be closed. The drives´s controller enabling signals must not be disconnected by the mains contactor. The mains contactor in the KVR drops out immediately when the emergency Mode of operation stop circuit is broken. The NC controller must brake the drives under position control. With the NCB link in circuit, if the power supply malfunctions, the set-point zeroing of the drive modules is suppressed. The drives must always be stopped by the master controller, i.e., the master controller must evaluate the UD contact of the KVR 1 and stop the drives when the contact opens. Otherwise, with a faulty power supply the drives can run uncontrolled. • DOK-POWER*-KVR*1.3****-ANW1-EN-E1,44 • 10.96 38 4.

Stopping the drives during an E-stop or mains fault NCB link Input - terminals X3/1 - X3/2 Link open closed controlled braking by the drive by the with emergency or electronics NC controller mains failure With the NCB link open, a mains fault or a fault inside the drive system is signalled to the drive. The drives brake at maximum torque. In the case of a drive fault, the power feed is also disconnected by the internal ready signal of the KVR. In a few applications (e.g., electronically-coupled gear-cutting machines), the drives have to be braked by the NC controller during an emergency stop or a mains fault. With the NCB link closed, then set-point zeroing is suppressed in the following faults: • faulty power supply – power failure/phase failure – link circuit voltage below 200 V • drive faults – open-circuit bus connection or faulty end plug – + 24 V / +/- 15 V signal voltage fault L M – overcurrent in the power circuit of the KVR – bleeder overloaded – heatsink temperature of the KVR too high This enables the drives to be stopped under position control during a mains failure or phase failure. The power regenerated during braking must exceed power consumption. During a drive fault, the power supply is always disconnected by the internal ready signal of the KVR. With the link closed, due to removal of the set-point zero circuit, the master controller must ensure that the drives are stopped, i.e., the master controller must evaluate the UD contact and stop the drives when the contact opens. Otherwise, if the power feed is removed, the drives can run uncontrolled. • DOK-POWER*-KVR*1.3****-ANW1-EN-E1,44 • 10.96 41 5. Description of Interfaces 5.5.

The Bb1 contact signals that the drive system is ready for the power to be applied. Only when it is closed, do the internal interlocks allow the power contactor in the KVR to be connected. In the event of a fault, the contactor is disconnected and the Bb1 contact opens. If the Bb1 contact is open, then a controlled braking of the drives can no longer be expected. It can, therefore, be used to enable the link circuit short-circuit to come into operation. The Bb1 contact closes if the supply to the electronics is applied to the terminal block X7/2U1/2V1/2W1 and no fault is present. The Bb1 contact opens during the following faults: – tachometer fault – overtemperature in the drive modules – bridge protection in drive modules – failure of the ±15 V / +24 V signal voltage M L – open circuit bus connection or faulty end plug – temperature of the KVR heatsink too high – overcurrent in the KVR power circuit – overvoltage – bleeder overloaded • DOK-POWER*-KVR*1.3****-ANW1-EN-E1,44 • 10.96 42 5.

If NC-controlled stopping is required, the drives must be stopped by the master controller when the UD contact is activated. 5.8. Temperature pre-warning Potential-free contact - Terminals X4/5 - X4/6 Load max.: DC 24 V/1 A Ready state relay temperature temperature Output TVW de-energized too high within permissible limits output open open closed The temperature pre-warning contact opens at unduly high heatsink tempera- tures. After 30 seconds, the mains contactor in the KVR interrupts the power supply and the Bb1 contact opens. The reaction of the drive system to this fault depends upon the NCB link (see section 5.4). If NC-controlled stopping is required, the drives should be stopped within 30 seconds, if the temperature pre-warning is activated in the KVR or one of the drive modules. • DOK-POWER*-KVR*1.3****-ANW1-EN-E1,44 • 10.96 44 5.

Fault-finding guidelines Because of the resulting production down-time, lengthy fault-finding and repairs to drive components on the machine are unacceptable. Thanks to their construction, INDRAMAT a.c. drives enable individual func- tional units to be easily and completely replaced without adjustments. This means that in the event of a fault, servicing is limited to fault-location either on the motor, the supply module or the drive module, or its complete replacement. 6.1. Fault-finding Because of the interaction between NC controller, supply and drive mod- ules, motor, mechanical system and position measurement, poor perform- ance of axis movements can be caused either by a fault in the above devices or if fitted with a comprehensive diagnostic system for rapid fault location. 6.2. Safety guidelines There is an increased accident risk when problems occur. Personnel, the plant and the drives are at risk. Localization of problems and the elimination of faults should only be performed by qualified personnel. Danger from drive movements: Guidelines on Undesirable drive movements are possible during the localization of prob- protection of personel lems. Unauthorized individuals should not remain within the hazardous area. Protective measures such as safety bars, covers and photo- electric barriers should not be removed. There must be free and ready access to the emergency stop switch. When working within the hazardous area, please note: When working within the hazardous area, the facility should be voltage free and secured against being switched on. Wait out the discharge time (approximately five minutes). Check intermediate circuit voltage. • DOK-POWER*-KVR*1.3****-ANW1-EN-E1,44 • 10.96 46 6. Fault finding guidelines Danger from live parts Dangerous electrical loads can occur at the following connections: • At all connections of the supply module and the corresponding chokes and capacitors, especially at mains connections 1U1, 1V1, 1W1 and 2U1, 2V1, 2W1, as well as the connections X13 and X14 of the fan supply. • At the drive modules, at the motor and the plugs of the motor connections. Before working on electrical equipment: – Switch power to the facility off with the main switch and secure it against the possibility of being turned on again. – Wait for the link circuit to discharge (approximately five minutes). Check the link circuit voltage. – Do not run motors. The motor connections will be electrically loaded if the motor is in motion. Before turning the equipment on: Only turn power on if the contact safety, delivered with the unit, is mounted. Guidelines on To avoid any damage to the machine: protecting the machine – Only authorized personnel should be permitted to start-up the facility. – Secure E-stop and limit switch functions. Guidelines on Prior to switching on: protecting the machine The wiring should agree with that of the KVR assembly plan. Check the course of the electricity throughout the unit. Electrostatic loads endanger electronic components. Electrostatic loads Discharge by grounding all objects that come into contact with the equipment. • DOK-POWER*-KVR*1.3****-ANW1-EN-E1,44 • 10.96 47 6. Fault finding guidelines 6.3.
