Rexroth servo cylinders with analog position measurement In the event of an abrupt change in the input signal, the system systems (potentiometers). Since the signals are processed in reacts with maximum dynamics. The times for accelerating or an analog manner and the module is only equipped with the braking a load are limited either by the available power or the most essential features required for performing a control ac- system gain. When a ramp function acts as an input value, the tion, we were able to keep the cost of the drive low. A further load is moved at a constant speed. speciality of this module is that it can be switched over inter- nally (front panel) to velocity control, and there is a version for voltage interface and a version for current interface, related to the setpoints and feedback signals. Velocity control* The setpoint and feedback signal of velocity are compared When a ramp function acts as an input signal, progressive and the difference transmitted to the valve amplifier. Through acceleration or deceleration with a constant value takes the process of integration, the signal is amplified to such an place. extent that even the smallest error is eliminated. * Only possible with a speedometer. 6/6 Bosch Rexroth Corp. | Industrial Hydraulics VT -MACAS | RA 30050/03.04 Device dimensions – dimensions in millimeters (inches) Wall mounting 86 x 110 x 95 DIN rail mounting (3.3 x 4.33 x 3.7 in) © 2004 Bosch Rexroth Corporation Bosch Rexroth Corp.
