Opt Net Loss

What does F072 mean?

Control over the installed network option card's remote network has been interrupted. This means the drive has lost communication via its optional network adapter (e.g., EtherNet/IP, DeviceNet, Profibus), leading to a loss of remote control and monitoring capabilities. The drive's response (e.g., fault, stop, coast) depends on its communication loss settings.

• Physical disconnection or damage to the network cable (e.g., EtherNet/IP, DeviceNet, Profibus) connected to the optional network card.
• Network infrastructure failure (e.g., switch failure, broken fiber optic link, power loss to network devices).
• Master controller (e.g., PLC) stopped communicating with the option card, or the option card itself has failed.
• Incorrect network configuration parameters on the drive's option card or the master controller (e.g., IP address, subnet mask, DeviceNet MAC ID).
• Excessive network traffic, latency, or collisions disrupting communication to the drive's option card.

Click steps to track your progress.

1. 1

   Verify the integrity and secure connection of the network cable to the drive's option card and the upstream network switch/controller.

2. 2

   Check the status LEDs on the option card and the network switch/hub for link activity and error indicators.

3. 3

   Confirm the master controller (PLC) is actively communicating with the drive's option card; check PLC network diagnostics.

4. 4

   Verify the option card's network configuration parameters (e.g., IP address P9-29, subnet mask P9-30 for EtherNet/IP; MAC ID for DeviceNet) match the network setup.

5. 5

   Attempt to ping the drive's IP address (if EtherNet/IP) from a workstation on the same network to confirm network connectivity.

6. 6

   If available, try replacing the option card with a known good spare to determine if the card itself is faulty.
