Description
Select inverter restart method,
Five option codes:
00...Alarm output after trip, no
automatic restart
01...Restart at 0Hz
02...Resume
frequency matching
03...Resume previous freq.
after freq. matching, then
decelerate to stop and
display trip info
04
...Resume operation after
active freq. matching
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:
00...Disable
01...Enable
02...Disable during stop and
decelerates to a stop
Two option codes:
00...Restart 16 times
01...Always restart
Restart the motor from 0Hz if
the frequency becomes less
than this set value during the
motor is coasting, range is 0 to
400Hz
