What causes EtHF [Embd Eth Com Interrupt] on the ATV340 series drives and how do I correct it?
Resolution:
The EtHF fault indicates a loss or interruption in Ethernet communication (EtherNet/IP or Modbus TCP) between the drive and the controlling device, preventing proper data exchange.
To resolve the issue, follow these steps:
- Verify all Ethernet connections and ensure cables are securely connected
- Replace the Ethernet cable to rule out cable failure
- Test a different port on the network switch or gateway
- Check network configuration and communication settings
- Refer to the ATV340 Ethernet user manual for additional troubleshooting guidance
