Description
Select inverter restart method,
Five option codes:
Alarm output after trip, no automatic
restart
Restart at 0Hz
Resume operation after frequency
matching
Resume previous freq. after freq.

display trip info
Resume operation after active freq.

The amount of time a power input
under-voltage can occur without tripping the
power failure alarm. Range is 0.3 to 25 sec. If
under-voltage exists longer than this time, the
inverter trips, even if the restart mode is
selected.
Time delay after under-voltage condition goes
away, before the inverter runs motor again.
Range is 0.3 to 100 seconds.
Three option codes:
Disable
Enable
Disable during stop and decelerates to a
stop
Two option codes:
Restart 16 times
Always restart
Restart the motor from 0Hz if the frequency
becomes less than this set value during the
motor is coasting, range is 0.00 to 400 Hz
