we have a customer using CtrlX drives and IAC valves for a new machine. what they found out was that
when there is a disruption in the ethercat network – either physically unplugging a network cable or pushing an online change – the ctrlx drives get the “F4002 Loss of consumer connection” fault. In the IAC valves this is “F4002 RTD telegram failure.” When this occurs on the IAC valves, they can reset the fault via the cyclic master communication. On the ctrlx drives, it’s like when this fault occurs they no longer respond to commands from the master. It will not respond to the reset command from the master and gets stuck in this faulted state. they confirmed that the correct reset bit is being set by the master. also found that by forcing the ethecat master into INIT mode and then back to OP mode, the drives also do an INIT->OP cycle and will again respond to the master commands. The F4002 fault remains after the reboot, but it can now be reset by the master. This fault can be cleared at any time via the physical control module on the front of the drive. Other faults can be reset from the master communication.
here is the system Info:
Beckhoff ethercat master
Reset by setting S-0-0099 bit 0 via the Signal Control Word S-0-0145 as part of the cyclic data
Ctrlx drives with firmware AXS-V-0402N
IAC valves with firmware HYDRV*-HDB-20V26.10
the question was why didn't ctrlX drives reboot the communication to OP automatically? and is there a parameter for setting the communication of drives to automatic reboot?
Thanks,
