What does F073 mean?
Control through the drive's embedded EtherNet/IP adapter has been interrupted. This signifies a loss of communication between the drive and its EtherNet/IP master controller or PLC, resulting in the loss of remote command and control capabilities and potentially triggering a fault or shutdown.
Complete Troubleshooting Guide
- 1
Cycle power to the drive to attempt to restore the EtherNet/IP communication link.
- 2
Check the Ethernet cabling for physical integrity, secure connections at both ends, and absence of damage.
- 3
Verify the EtherNet/IP setting parameters in the drive (e.g., IP address, subnet mask, gateway) match the network configuration.
- 4
Check the external network status and the PLC/controller's diagnostic information for network-wide issues or specific faults related to the drive's IP address.
