then decelerate to stop
and display trip info
The amount of time a
under-voltage can occur
without tripping the power
Allowable
failure alarm. Range is
0.3 to 25.0 sec. If
failure time
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
