Cause : Permanent magnet synchronous motor is rotating, start mode 2 (DC MAGN) is selected with
parameter 2101 START FUNCTION,
and run is requested.
Drive warns that rotating motor cannot be magnetized with DC current.
If start to rotating motor is required, select start mode 1 (AUTO) with parameter 2101 START FUNCTION. Otherwise drive starts after motor has stopped.
