Cause : Option fault comes when a contact fault, etc. of the connector between the inverter and plug-in option occurs or if a communication option is fitted to the connector 1 or 2.
Appears when the switch for the manufacturer setting of the plug-in option is changed.
- Check that the plug-in option is plugged into the connector securely.
- Check for excess electrical noises around the inverter.
- Check that the communication option is not fitted to the connector 1 or 2.
