B001 Selection of automatic
restart mode
R/W Select inverter restart method,
Four 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

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.
10A6h 3 to 250 0.1 sec
B003 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.
10A7h 3 to 1000 0.1 sec
B004 Instantaneous power
failure / under-voltage
trip alarm enable
R/W Two option codes:
00…Disable
01…Enable

B011 Start freq to be used in
case of freq pull-in
restart
R/W Three option codes:
00…freq at previous shutoff
01…start from max. Hz
02…start from set frequency
