B002
Allowable under-
voltage power failure
time
R/W 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
R/W Time delay after under-voltage
condition goes away, before the
inverter runs motor again.
Range is 0.3 to 100 seconds.
