Troubleshooting
Type Cause Remedy
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 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.
Starting torque is insufficient. Change to vector control
operation mode. If the fault is still
not corrected, replace the
inverter with a model with
increased capacity.
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 even with
Dynamic Braking (DB)
resistor connected. 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. Replace the motor with a
model with increased capacity.
The load is higher than the internal
torque limit determined by the
rated current of the inverter. Replace the inverter with a model
with increased capacity.
Operation is difficult in The carrier frequency is too high. Reduce the carrier frequency.
