"B" Group Fine Tuning Functions
R/W Description
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.
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.
R/W Time delay after under-
voltage condition goes away,
before the inverter runs motor
again.
Range is 0.3 to 100 seconds.
R/W Two option codes:
00... Disable
01... Enable
R/W Two option codes:
00... Restart 16 times
01... Always restart
R/W Set a level between 20% and
120% for the rated inverter
current
R/W
R/W Select from two curves,
option codes: *1
00... Reduced torque 1
R/W
01... Constant torque
02... Reduced torque 2
