Speed Controller - Siemens SINAMICS S120 Function Manual

Servo control

3.1 Speed controller

3.1 Speed controller
The speed controller controls the motor speed using the actual values from the encoder
(operation with encoder) or from the calculated actual speed values (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.
