Issue:
Getting a ETHF embedded ethernet com interrupt fault on the ATV630 and ATV930 process drives.
Product Line:
ATV630 and ATV930 drive
Environment:
All with built in Ethernet
Cause:
Communication interruption on the Ethernet ModbusTCP bus.
Resolution:
Keep in mind that if the PLC or controller is not writing a command or reference to the drive within the programmed TTOB (Ethernet timeout or Hold up time) the Drive can trip on ETHF fault.
