Servo control
3
This type of closed-loop control enables operation with a high dynamic response and
precision for a motor with a motor encoder.
3.1 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.
