Troubleshooting

Type Cause Remedy
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
not accelerate.
/The
acceleration
time is too long.
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. 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.
Motor speed
varies during
operation.
There is a high variance in load.
Replace the motor and inverter with
models with increased capacity.
The input voltage varies. Reduce 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
The deceleration time is set too long. Change the setting accordingly.
The motor torque is insufficient.
If motor parameters are normal, it is
likely to be a motor capacity fault.
