Cause : Communication option fault comes when the inverter trips if a communication line error occurs in the communication option.
- Check for an incorrect option function setting and operation.
- Check that the plug-in option is plugged into the connector properly.
- Check for a break in the communication cable.
- Check that the terminating resistor is fitted properly.
- Check the option function setting, etc.
- Connect the plug-in option securely.
