Protective functions
870 Speed deviation level
If the difference between speed command value and speed exceeds the setting of the
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.

875 Fault definition
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.
0: Immediate output shutoff
1: Output shutoff after deceleration to stop (Immediate output shutoff other than OHT
and THM)

adaptive speed
control selection
Select speed feed forward control (which improves the motor trackability in response to
a speed command change (during acceleration/deceleration)) or model adaptive speed
control (that can adjust speed trackability and motor disturbance torque response level
individually). (0: No selection, 1: Speed feed forward control, 2: model adaptive speed
control)
