List of Holding Registers
Name R/W
R/W Select the operation mode during
overload conditions, three
options, option codes:
00 Disables
01 Enabled for acceleration and
02 Enabled for constant speed
R/W Sets the level for overload
restriction, between 20% and
150% of the rated current of the
R/W
inverter, setting resolution is 1%
of rated current
R/W Sets the deceleration rate when
inverter detects overload, range
is 0.1 to 30.0, resolution 0.1
R/W
R/W Two option codes:
00 set value of B022
01 [O] input
R/W Two option codes:
00 set value of B222
01 [O] input
R/W Sets the deceleration rate when
frequency pull-in restart, range
is 0.1 to 3000.0, resolution 0.1
R/W Sets the current level of
frequency pull-in restart, range
is 0.2*inverter rated current to
2.0*inverter rated current,
resolution 0.1
R/W Prevents parameter changes, in
four options, option codes:
00 all parameters except B031
01 all parameters except B031
02 all parameters except B031
03 all parameters except B031
10 High level access including
R/W Two option codes:
00 Disabled
01 Enabled
R/W Setting of DC bus voltage to start
non stop operation. Range is 0.0
to 1000.0
