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 0 Hz
02... Resume operation after fre-
quency matching
03... Resume previous freq. after
freq. matching, then deceler-
ate to stop and display trip
info
04... Resume operation after
active freq. matching
8 00 –
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.
8 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.
8 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
8 00 –
B005 Number of restarts on power
failure / under-voltage trip
events
Two option codes:
00... Restart 16 times
01... Always restart
8 00 –
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
*1
8 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 0 Hz
02... Resume operation after fre-
quency matching
03... Resume previous freq. after
active freq. matching, then
decelerate to stop and dis-
play trip info
04... Resume operation after
active freq. matching
8 00 –
b010 Number of retry on over volt-
age / over current trip
Range is 1 to 3 times 8 3times
b011 Retry wait time on over voltage
/ over current trip
Range is 0.3 to 100 sec. 8 1.0 sec
*1
Up to 1000Hz for High frequency mode (d060 set to "2")
