Checking point
Corrective Action
Is the power applied
Turn the power OFF and then ON again.
Make sure the input line voltage is correct.
Make sure all terminal screws are secured
firmly.
Turn the power OFF and then ON again.
Reduce the load to improve performance.
See error descriptions to check wiring and cor-
rect if necessary.
Is analogue frequency input signal wiring correct
Is frequency input voltage correct
Configure operations through the digital panel
Wiring must match U, V, and W terminals of the
motor.
Check wiring and correct if necessary.
Check wiring and correct if necessary.
Check the operation mode setting on the key-
pad.
Reduce the load.
Confirm the motor's specifications.
Confirm the gear ratio.
Confirm the highest output frequency.
