Hey folks,
i'm trying to retrofit an old Maho400E in the near future with a Beckhoff EM7004 in combination with a costum adaptor-board for the 3 axis and wanted to prepare the electronics as far as possible. In addition to that i also want to implement a Danfoss VFD FC302 with its EtherCAT optioncard MCA124. I started to read out all the PDO mappings and so on, like in many other forum posts described, but now i don't know how to proceed with the Flag E and the dmesg output, that the VFD would not support distributed clocks. You can find all configs and readouts of the VFD on my Github . The most important stuff is also attached here.
Thank you guys for your help
Best regards
Patrick

Did you find a solution? What version of LinuxCNC are you running?
I have a similar issue. It was running fine with LinuxCNC version 2.8, but after upgrading to 2.9.3 I get "PREOP E" errors and the drives won't enable. It seems to be random which drives go to PREOP E and which ones go to OP. Restarting LinuxCNC multiple times gives random results.
I get sync manager timeouts and failures to write SDO's.

If you are having SDO write failures you may need to disable EoE by rebuilding the IgH master from source. If you search the forum for "disable eoe" there are several post about it and what flags are needed to build from source without EoE.
