Activate/deactivate the current controller feedforward control
• Since the positioning movements are known, they can be precontrolled in order to slightly increase the
achievable dynamic performance of the control loop.
Note!
A successful feedforward control requires knowledge of the equivalent circuit data of the motor. If only estimated
values are available, the feedforward control should not be activated.
