CAUTION

Wait at least 5 minutes after turning the input power OFF before starting

inspection.
Failure to do so could lead to electric shock.

Maintenance, inspection and part replacement must be done by qualified

persons.
(Remove all metal personal belongings (watches, bracelets, etc.) before
starting work.)
(Use tools treated with insulation.)
Failure to do so could lead to electric shock or injury.

1. The motor does not rotate (when fault display is not lit)

Troubleshooting (1)

Is the power voltage correct?

Yes

Is "000" displayed on the panel?

Press the MODE button to display "000".

Yes

Turn the local or external run signal
ON.

Yes

∗

Check the run signal and setting.

Set the frequency setting value to 0.5Hz
or more.

The frequency does not appear, or
there is no output voltage.

The inverter is faulty. (Contact Matsushita)

Voltage is supplied to the motor.

The motor is faulty.

Yes

∗

Check the frequency setting signal and

setting.
