FVR-C11S-EN

4) When motor generates abnormal heat

Motor generates abnor-

mal heat

V/f pattern fitted to mo-

tor?

Change the setting.

Yes

Motor been

continuously operated

at extremely low

speed?

Yes

Use motor exclusive to

inverter.

Load excessive?

Yes

Lighten load or in-

crease motor capacity.

Is the output voltage

(at terminals U,V,W)

balanced?

Yes

Faulty motor.

Probably faulty inverter.
