Net Loss

What does F71 mean?

This fault occurs when communication is lost with the network connected to the drive. This means the drive is no longer receiving commands or transmitting data via its communication interface.

• Loss of communication with the main control network (e.g., Ethernet/IP, Profibus).
• Faulty network cable or connector.
• Network switch or router malfunction.
• Incorrect network configuration (IP address, station address).

Click steps to track your progress.

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.
