Allowable
under-voltage
power failure time
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.

Retry wait time
before motor
restart
Time delay after under-voltage condition goes
away, before the inverter runs motor again.
Range is 0.3 to 100 seconds.
