or trips when the bus is not energized. If this settings is programmed to "Yes", at least one
voltage must be greater than 20% of the nominal nameplate voltage rating for any alarm/
trip. If the load is high inertia, it may be desirable to trip the motor off-line or prevent it from

ensures that the motor is tripped and may be restarted only after the bus is re-energized.
