Troubleshooting
246 GM2 Series VFD

Items Cause Remedy
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 greater than the
maximum voltage.
Only use motors suitable for applications
with inverters.
Connect the AC reactor to the inverter
output (lower the carrier frequency).
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
or when connected
to load.
The load is too high.
Reduce the load.
Replace the motor and/or the inverter
with larger models.
The motor does not
accelerate.
The frequency reference value is low. Set an appropriate value.
The load is too high.
Reduce the load. Increase the
acceleration time.
Check the mechanical brake status.
The acceleration time is too long. Change the acceleration time.
The combined values of the motor
properties and the inverter parameter
are incorrect.
Change the motor related parameters.
The stall prevention level during
acceleration is low.
Change the stall prevention level.
The stall prevention level during
operation is low.
Change the stall prevention level.
Starting torque is insufficient.
Change to vector control operation
mode. If the fault remains, replace the
inverter with a larger model.
Motor speed varies
during operation.
There is a high variance in load.
Replace the motor and/or the inverter
with larger models.
The input voltage varies. Correct the input voltage variation.
Motor speed variations occur at a
specific frequency. Adjust the output frequency to avoid a
resonance area.
The motor rotation
is different from the
setting.
The V/F pattern is set incorrectly.
Set a V/F pattern that is suitable for the
motor specification.
The motor
deceleration time is
too long even with
Dynamic Braking
(DB) resistor
connected.
The deceleration time is set too long. Change the setting accordingly.
The motor negative torque is excessive.
Check DB Resistor circuit operation.
Investigate alternate braking methods.
Replace the motor and/or the inverter
with larger models.
Operation is difficult
during light load
conditions.
The carrier frequency is too high. Reduce the carrier frequency.
Over-excitation has occurred due to an
inaccurate V/F setting at low speed. Reduce the torque boost value to avoid
over-excitation.
While the inverter is
in operation, a
control unit
malfunctions or
noise occurs.
Noise occurs due to switching inside the
inverter.
Change the carrier frequency to the
minimum value.
Install a micro surge filter in the inverter
output.
