Chapter 5 Trouble shooting and maintenance
Remedy
Is the power applied?
Turn the power OFF and then ON
again.
Make sure the power voltage is
correct.
Make sure terminals are fully
tightened.
Turn the power OFF and then ON
again.
Reduce the load to allow the motor
to rotate.
See error descriptions to check wiring
and correct if necessary.
‧Is analog frequency input signal
wiring correct?
Is voltage of frequency input
correct?
‧Check parameter setting
Wiring must match U, V, and W
terminals of the motor.
Check wiring is correct if necessary.
Check wiring is correct if necessary.
Check the operation mode setting at
the keypad.
Reduce load.
Confirm the motor's specifications.
Confirm the gear ratio.
Confirm the highest output
frequency.
Reduce the load.
Minimize the variation of the load.
Increase capacities of the inverter
and the motor.
Add an AC reactor at the power
input side if using single-phase
power.
Check wiring if using three-phase
power.
