Opt Net Loss
Allen-Bradley · PowerFlex 520-series Adjustable Frequency
Was bedeutet F072 ?
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.
Häufige Ursachen
- 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.
Reparaturschritte & Checkliste
Klicken Sie auf Schritte, um Ihren Fortschritt zu verfolgen.
- 1
Verify the integrity and secure connection of the network cable to the drive's option card and the upstream network switch/controller.
- 2
Check the status LEDs on the option card and the network switch/hub for link activity and error indicators.
- 3
Confirm the master controller (PLC) is actively communicating with the drive's option card; check PLC network diagnostics.
- 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
Attempt to ping the drive's IP address (if EtherNet/IP) from a workstation on the same network to confirm network connectivity.
- 6
If available, try replacing the option card with a known good spare to determine if the card itself is faulty.
