Speed controller

Function description
For operation with a controller, the speed controller regulates the speed of the motor based on
the actual values of the encoder. For operation without a controller, the speed controller
regulates the speed of the motor based on calculated speed actual values.
Special characteristics of the speed controller include:
● 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 r1082[D] is preset with the default value of the selected motor and
becomes effective upon commissioning. The ramp-up and ramp-down times for the encoder
relate to this value.
