0x2941 Current controller feedforward control Acvate/deacvate feedforward control.
Since the actuaon of the current controller is known, they can be pre-
c
ontrolled to increase the actuaons of the current controller.
Note!
For a feedforward control, the Motor equivalent circuit diagram data
must be known. If only esmated values are available, we recommend
you not to acvate the feedforward control.
