Troubleshooting
Type Cause Remedy
overheating. Increase the Acc/Dec time.
Check the motor parameters and set
the correct values.
Replace the motor and the inverter
with models with appropriate
capacity for the load.
The ambient temperature of the motor
is too high. Lower the ambient temperature of
the motor.
The phase-to-phase voltage of the
motor is insufficient.
Use a motor that can withstand
phase-to-phase voltages surges
greater than the maximum surge
voltage.
Only use motors suitable for
applications with inverters.
Connect the AC reactor to the inverter
output (set the carrier frequency to 3
kHz).
The motor fan has stopped or the fan is
obstructed with debris. Check the motor fan and remove any
foreign objects.
The motor stops
during
acceleration.
The load is too high.
Reduce the load.
Increase the volume of the torque
boost.
Replace the motor and the inverter
with models with capacity
appropriate for the load.
The current is too big.
If the output current exceeds the
rated load, decrease the torque boost.
The motor stops
when connected
to load.
The load is too high.
Reduce the load.
Replace the motor and the inverter
with models with capacity
appropriate for the load.
The motor does The frequency command value is low. Set an appropriate value.
