Drive functions

7.1 Servo control

This type of closed-loop control enables operation with a high dynamic response and

precision for a motor with a motor encoder.

7.1.1 Speed controller

The speed controller controls the motor speed using the actual values from the encoder

(operation with encoder) or the calculated actual speed value from the electric motor model

(operation without encoder).

Properties

● Speed setpoint filter

● Speed controller adaptation

Note

Speed and torque cannot be controlled simultaneously. If speed control is activated, this has

priority over torque control.

Limits

The maximum speed p1082[D] is defined with default values for the selected motor and

becomes active during commissioning. The ramp-function generators refer to this value.
