Servotronix Ethercat problem was created by Neiji_msk
Hello everyone, I have a small problem. I have three VEICHI drives connected via Ethercat in my system. My task was to connect a fourth driver to them, but from a different manufacturer (Servotronix CDHD2S). I purchased this driver, and everything works fine with the PC. Then I connected the driver to the common system with the other drivers via Ethercat, configured it, and added vid and pid. As a result, Linux CNC starts, but the driver hangs in an error and does not switch from PREOP to OP. Please advise what the problem might be. I am attaching my configurations and the xml from the driver manufacturer.

Can you please show the last say 30 lines from the syslog after you tried to start linuxcnc.
The ethercat master writes errors there
Output of "sudo dmesg | tail -30"

My Linux runs fine. It's just that the driver doesn't switch to enable mode, but the other three axes work. I think the problem might be with vid and pid.
