The nSt Error is for the Freewheel stop of the motor .
The assignment of the "Fast stop" or "Freewheel stop" functions will prevent the drive from starting if the corresponding logic inputs are
not powered up. The ATV31 then displays "nSt" in freewheel stop mode and "FSt" in fast stop mode. This is normal since these functions
are active at zero so that the drive will be stopped safely if there is a wire break.
