The above is what may magically happen if you have the perfect Acontis stack supporting PMAC unit with the right firmware and proper IDE version combination, extreme luck and the proper interplanetary alignment of galaxies.
Reality is that it took weeks of reading and effort between a CK3E and a PowerClipper unit to connect to Kollmorgan drive and even when it worked, it just released the brake and before I had a chance to send a new value to make motor spin the ethercat bus would time out, IDE would crash and lots of CTRL+ALT+DEL + END-TASKs, service restarts and a few minutes of reloads and reboots later while searching the forum for the 1209421812908 time for anyone else maybe experiencing the same, low and behold a new firmware version is released and the release notes describe issue experienced above as now fixed for acontis stack only when I only had the Etherlab PoweClipper unit. Fast-forward nearly a year and a CK3E now sits on my desk with the proper acontis ethercat stack that is supposed to actually work. Right next to it there is an ethercat Omron NX coupler which I was once able to connect to the other unit that I no longer have access to, but have yet to succeed on CK3E despite following instructions - the NX may not have the right firmware that supports distributed clock = next step to verify on this, meanwhile projects need to move forward and Beckhoff/Siemens/etc just work so that's what gets used since there is only so much time one can invest in the absurd learning curve needed to master the intricacies to get this hardware on ethercat bus up and running.
If you are looking for intuitive, easy, reliable, mature or broadly supported I would look elsewhere. Just about a week ago I was looking for firmware updates / checking how CK3E support has progressed since I last touched it nearly a year ago, only to find out all CK3E firmware files have been pulled from the filedepot and to contact support by phone if help needed - in short - the prior transparency with error fixes in release notes and ongoing support progress visibility is now gone and whatever issues I run into I can no longer check if a different firmware version may have resolved.
Good luck - I will keep an eye on this thread to see if your ultimate results are better than mine, hopefully that will give me motivation to keep trying on the CK3E and stop using it as a paperweight on my desk reminding me daily to never buy another item like this without first finding a real world customer who successfully implemented same setup I envision for it.
Hi dougjr17!
Finally, how was your experience with the Kollmorgen Drive an EtherCAT interface? Now a days i'm studding to use this alternative to our system. I don't know really if actually all the IDE and Stack of EtherLab are improved. Did you get some success goals with PMAC-EtherCAT-Kollmorgen systems?
Thanks and regards
