I have done this, and get a phase loss error at the Yaskawa drives. This error shows up as soon as we try to move any axis. I have a JUSP handheld device and am comfortable working on the machine and drives. Any help on this would be appreciated. I can run the machine on a rotary phase convertor just fine - it is just noisy and I'd much rather get the machine running without it. I would appreciate any input on this.
Thanks much.
