OK, I had a chance to probe the machine for voltages. I found some interesting readings and eventually, after a few on/off cycles of the step-up transformer it seems to have stopped working. I have 3-phase voltage going in to the transformer at 115v for each leg to ground. I should have about 230 for each leg on the output side of it going into the main disconnect of the Hurco. At first I measured about 300V on one leg, 90v on another and about 230v on the third.

From what I can gather by looking at the system, the very first place the input power goes after the disconnect switch and the main fuses is into a 460V to 230V step-down transformer. Why in the heck would I step up perfectly good 230V, 3-phase power to 460V only to step it immediately down to 230 again? The only reason I can see would be so that there wasn't as much amperage flowing through the main switch and fuses.

Can someone please tell me if I can run this machine off of the 230V 3Ph power coming in and if so how would I best go about this? I'm decent with schematics and I'm not afraid to change the wiring.

I'm not trying to run it on single phase power, which I've seen people do with various phase converters. I just want to get it going and try to boot it.

Thanks in advance,
Justin
