Cause : Comm Loss comes when communications between the drive and the Modbus or DSI master device have been interrupted.
1. If adapter was not intentionally disconnected, check wiring to the port. Replace wiring, port expander, adapters or complete drive as required.
2. Check connection.
3. An adapter was intentionally disconnected.
4. Turn off using C304 [Comm Loss Action].
