Cause : Cyclical communication between drive and fieldbus adapter module A or between PLC and fieldbus adapter module A is lost.
1. Check status of fieldbus communication.
See user documentation of fieldbus interface.
2. Check settings of parameter groups 50 Fieldbus adapter (FBA), 51 FBA A settings, 52 FBA A data in and 53 FBA A data out.
3. Check cable connections.
4. Check if communication master is able to communicate.
