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.
