1. 1

   Verify the physical network cable connection to the drive's communication port (e.g., RS485/DSI terminals 8 and 1).

2. 2

   Check the operational status of other devices on the communication network for faults or disconnections.

3. 3

   Ensure all network communication parameters (e.g., A103 [CommData Rate], A104 [CommNode Addr], A107 [CommFormat]) are correctly configured and match the network settings.
