Name
If the difference between speed command value and speed exceeds the setting of the
870 Speed deviation level
speed deviation level (Pr. 870) for longer than the setting of the speed deviation time
(Pr. 871), speed deviation excessive "E.OSD" is displayed and the motor stops.

You can classify faults into a minor fault and major faults according to the alarms, and
make setting to select between immediate output shutoff and output shutoff after
deceleration to stop.
