Cause : M/F comm loss comes when master/follower communication is lost.
- Check the auxiliary code.
- The code indicates which node address (defined by parameter 60.2 in each drive) on the master/follower link is affected.
- Check settings of parameter group 60 DDCS communication.
- On the FDCO module (if present), check that the DDCS link switch is not set to 0 (OFF).
- Check cable connections. If necessary, replace cables.
