Code
Name R/W Description
Network Data
Reg. Range Res.
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.
0089h 0, 1, 2, 3 —
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.
008Ah 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.
008Bh 3 to
1000
0.1 sec
B004 Instantaneous power
failure / under-voltage
trip alarm enable
R/W Two option codes:
00...Disable
01...Enable
008Ch 0, 1 —
B005 Number of restarts on
power failure / under-
voltage trip events
R/W Two option codes:
00...Restart 16 times
01...Always restart
008Dh 0, 1 —
B012 Level of electronic
thermal setting
R/W Set a level between 20% and
120% for the rated inverter
current
008Eh 2000 to
