Cause : INU-LSU comm loss comes when DDCS (fiber optic) communication between converters (for example, the inverter unit and the supply unit) is lost.
- Check settings of parameter group 160 DDCS communication.
- Check the corresponding settings in the control program of the other converter.
- Check the cable connections. If necessary, replace the cables.
