14. Troubleshooting

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

Is the power voltage normal?

Yes

Is "0000" displayed on the panel?

Press the MODE button to display "0000".

Yes

Turn the local or external run signal ON.

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. (Please inquire.)

Voltage is supplied to the motor.

The motor is faulty.

Yes

2. The motor does not rotate (When fault display is lit).

If the phenomenon occurs for the first

time or immediately after installation.

Remove inverter load wiring from

terminals U, V and W.

Yes

Turn the local or external run signal ON.

Appear OC1, etc. on the page 196.

Yes

The inverter malfunction. (Please inquire.)

When one of faults on page 196 is displayed and the motor has not rotated, check the

following two points:

①

Check whether this is the first time (or immediately after installation) power has been

applied to the inverter, or it has been in use.

②

Check if this is an inverter malfunction (failure), a wiring, or a motor malfunction.

* Check the run signal and setting data.

* Check the frequency setting signal and

setting data.

Note) If OC1, etc. on page 196 appears, take

measures to dealing with such situations

according to each indication.

Caution

●

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

and 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.
