What would cause EPF2 fault on ATV32 when communicating with Ethernet?

Product Line:


FDR detected fault
IP address duplication detected fault

First check the FDR on the Ethernet IP card is disabled. In case the FDR is enabled, that will explain the "EPF2" fault. The reason is that the Drive is waiting for a configuration from PLC but PLC don't answer once the timeout is reached. This causes the drive to trip in "EPF2".
The second reason for "EPF2" fault is the range of IP address. In case of IP address 192.0.0.x and Sub net mask of can cause "EPF2". Change the range of IP address.
