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

b010
Number of retry on over
voltage / over current trip
Range is 1 to 3 times
U

times
b011
Retry wait time on over voltage
/ over current trip
Range is 0.3 to 100 sec.
U
