Overcurrent
shut-off
during
acceleration
When the inverter output current
reaches or exceeds approximately 200%
of the rated current during acceleration,
the protective circuit is activated to stop
the inverter output.
• Check the
motor cable
insulation and
connection for
output short-circuit/
ground fault.
Repair the wiring.
Overcurrent
shut-off
during
constant speed
When the inverter output current
reaches or exceeds approximately 200%
of the rated current during constant
speed, the protective circuit is activated
to stop the inverter output.
• Check the
motor cable
insulation and
connection for
output short-circuit/
ground fault.
Repair the wiring.
Overcurrent
shut-off
during
deceleration
When the inverter output current
reaches or exceeds approximately 200%
of the rated current during deceleration
(other than acceleration or constant
speed), the protective circuit is activated
to stop the inverter output.
a.Check for sudden
speed reduction.
b.Check the motor
cable insulation and
connection for
output short-circuit/
ground fault.
a.Contact Alliance
Laundry Systems’
Customer Service
department.
b.Repair the wiring.
Regenerative
overvoltage
shut-off
during
acceleration
If regenerative energy causes the
inverter’s internal main circuit DC
voltage to reach or exceed the specified
value, the protective circuit is activated
to stop the inverter output. It may also
be activated by a surge voltage
generated in the power supply system
Check to make sure
the machine is
loaded properly and
that the load is
balanced.
Load the machine
properly to
distribute the load
evenly.
