Does SUPPORT ETHERCAT actually tell you anything useful about a servo drive?
I’ve been looking at servo platforms lately and ethercat support almost feels like a checkbox now. The more interesting differences seem to show up after that. That’s part of why I’ve been looking more closely at platforms from Beckhoff, Yaskawa, Elmo Motion Control and others instead of just comparing protocol support. Elmo especially caught my attention around compact multi-axis systems, where synchronization and drive footprint can both become design constraints.
At this point I’d rather see vendors benchmark actual multi-axis behavior than advertise “EtherCAT supported.”
What has actually separated a good EtherCAT servo implementation from an average one in your experience?
