Hello everyone,
I just bought a Mazak QT8 CNC lathe. It came with an American Rotary AD10 converter and I put it in my residential garage. Everything is wired and operational, and when demand is low (reduced rapids and slower spindle speeds) everything works fine. But when performance is required, I get a X axis servo alarm. I suspect the rotary phase converter is undersized and allowing the voltage to drop.
Here is the question. Can I add a 3 HP 3 phase motor to run with the idler to help prevent the problem? I have the 3 hp motor on the shelf for another project, so it would be easy to try it. I also have a 3 HP knee mill currently wired with a static converter. It would be easy to remove the static and wire it to the rotary, as well.
I seem to recall the loads will add up to help start larger motors, but my research today has failed to turn it up.
Thanks!
