Craig, you were close!
However, that is not my Matsuura, but one just like it at the shop in Maine. And yes, it is running on KingStar EtherCAT. We are pretty excited about having an EtherCAT solution and it is working very well. That machine has an EtherCAT spindle drive (TDE MACNO) but the spindle can be controlled with analog outputs as well. It is using Yaskawa Sigma 7 servo drives with ABS encoders and an Omron I/O "brick" None of that was cheap! Probing is handled on the servo modules as the servo drives have a bit of I/O on them for such uses. ABS encoders means no homing required! It is a slick setup.
You don't have to run EVERYTHING on the machine with EtherCAT. You can use I/O to run just about anything in the traditional manner. So the main EtherCAT devices would be the servo drives and some I/O modules. The spindle can optionally be controlled via EtherCAT, but as I said, an analog control method is also provided with plans to accept encoder input (via an encoder input I/O module) for rigid tapping/threading capability (not there yet but coming soon).
Maybe we can do a video of the Matsuura showing it's control cabinets and running it through some paces. I do love those old Matsuura machines. Good iron. Super rigid. They are old school machines with box ways and 5K spindles so they are not really setup for the high speed machining stuff. But you can use a hog cutter end mill and remove amazing amounts of material per pass. That is IF you can clamp the part well enough.
BTW, I also have some Leadshine EtherCAT stepper drives that are fixing to run my desktop test machine. Talk about OVERKILL!!! EtherCAT running NEMA 17s. LOL!
