Overload Restriction
If the inverter's output current exceeds a
preset current level you specify during
acceleration or constant speed, the overload
restriction feature automatically reduces the
output frequency to restrict the overload.
This feature does not generate an alarm or
trip event. You can instruct the inverter to
apply
constant
currents for acceleration. Or, you may use
the same threshold for both acceleration and
constant speed.
When the inverter detects an overload, it
must decelerate the motor to reduce the
current until it s less than the threshold. You
can choose the rate of deceleration that the
inverter uses to lower the output current.

Description
Select the operation mode during
overload conditions, three
options, option codes:
00...Disabled
01...Enabled for acceleration and
constant speed
02...Enabled for constant speed
only
Sets the level for overload
restriction, between 20% and
150% of the rated current of the
inverter, setting resolution is 1%
of rated current
Sets the deceleration rate when
inverter detects overload, range
is 0.1 to 30.0, resolution 0.1
