control panel side is incorrect.
The motor only
rotates in one
direction.
Reverse rotation prevention is selected.
Remove the reverse rotation
prevention.
The reverse rotation signal is not
provided, even when a 3-wire
sequence is selected.
Check the input signal associated
with the 3-wire operation and adjust
as necessary.
The motor is
overheating.
The load is too heavy.
Reduce the load.
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 amount 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
not accelerate.
The frequency command value is low.
Set an appropriate value.
The load is too high.
Reduce the load and increase the
acceleration time. Check the
mechanical brake status.
The acceleration
time is too long.
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.
