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
decelerate to stop and display
trip info.

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 04262 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.

B004 Instantaneous power
failure / under-voltage
trip alarm enable R/W Two option codes:
00... Disable
01... Enable

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