0x2941 Current controller feedforward control Activate/deactivate feedforward control.
Since the actuation of the current controller is known, they can be pre-
controlled to increase the actuations of the current controller.
Note!
For a feedforward control, the Motor equivalent circuit diagram data
must be known. If only estimated values are available, we recommend
you not to activate the feedforward control.
