Cause : Cyclical communication between drive and fieldbus adapter module or between PLC and fieldbus adapter module is lost.
Programmable fault:
50.02 Comm loss function
Check status of fieldbus communication.
See the appropriate User’s Manual of fieldbus adapter module.
Check settings of parameter group 50 Fieldbus.
Check cable connections.
Check if communication master is able to communicate.
