568
Type
Cause
Remedy
Ground Trip
A ground fault has occurred in the
inverter output wiring.
Check the output wiring.
The motor insulation is damaged.
Replace the motor.
E-Thermal
The motor has overheated.
Reduce the load or operation frequency.
The inverter load is greater than the
rated capacity.
Replace the inverter with a model that has
increased capacity.
The set value for electronic thermal
protection is too low.
Set an appropriate electronic thermal level.
The inverter has been operated at low
speed for an extended duration.
Replace the motor with a model that
supplies extra power to the cooling fan.
Out Phase
Open
The magnetic contactor on the output
side has a connection fault.
Check the magnetic contactor on the
output side.
The output wiring is faulty.
Check the output wiring.
In Phase
Open
The magnetic contactor on the input
side has a connection fault.
Check the magnetic contactor on the
input side.
The input wiring is faulty.
Check the input wiring.
The DC link capacitor needs to be
replaced.
Replace the DC link capacitor. Contact the
retailer or the LSIS customer service center.
Inverter OLT
The load is greater than the rated motor
capacity.
Replace the motor and inverter with
models that have increased capacity.
The torque boost level is too high.
Reduce the torque boost level.
Over Heat
There is a problem with the cooling
system.
Determine if a foreign object is obstructing
the air inlet, outlet, or vent.
The inverter cooling fan has been
operated for an extended period.
Replace the cooling fan.
The ambient temperature is too high.
Keep the ambient temperature below
50
℃
.
Over
Current2
Output wiring is short-circuited.
Check the output wiring.
There is a fault with the electronic
semiconductor (IGBT).
Do not operate the inverter. Contact the
retailer or the LSIS customer service center.
NTC Open
The ambient temperature is too low.
Keep the ambient temperature above -
10
℃
.
