B001
Restart mode on power failure
/ under-voltage trip
Select inverter restart method,
Five option codes:
00…Alarm output after trip, no
automatic restart
01…Restart at 0Hz
02…Resume operation after
frequency matching
03…Resume previous freq. after
freq. matching, then decelerate
to stop and display trip info
04…Resume operation after active
freq. matching

B002
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.
U
1.0 sec.
B003
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.
U
1.0 sec.
B004
Instantaneous power failure /
under-voltage trip alarm
enable
Three option codes:
00…Disable
01…Enable
02…Disable during stop and
decelerates to a stop

B005
Number of restarts on power
failure / under-voltage trip
events
Two option codes:
00…Restart 16 times
01…Always restart
U

b007
Restart frequency threshold Restart the motor from 0Hz if the
frequency becomes less than this
set value during the motor is
coasting, range is 0 to 400Hz
U
0.00 Hz
b008
Restart mode on over voltage /
over current trip
Select inverter restart method,
Five option codes:
00…Alarm output after trip, no
automatic restart
01…Restart at 0Hz
02…Resume operation after
frequency matching
03…Resume previous freq. after
active freq. matching, then
decelerate to stop and display
trip info
04…Resume operation after active
freq. matching

times
b011
Retry wait time on over voltage
