The UVW will be commutation signals for the drives. (brushless motors are commutated in the drives, not in the motor).
If those signals exist then the choice of drives is much expanded.

Is there a DC power supply in the system, or do the axis drives take AC input?

I suspect that the easiest solution would be Granite Drives though cheaper options include the Mesa 8i20 (requires separate DC power supply) and "Whatever turns up on eBay at a good price"

It might well be simplest just to find a stock of spares of the original drives.

Thanks for the education. Servos and their drives are new to me. The UVW does exist in the encoders, I've seen the connections with my own eyes. These drives take 200V AC +-10%. I checked them yesterday and they are receiving 189V. I'll research those options. I have to go back through and troubleshoot it again as I keep getting different faults depending on my jog speed settings. It always faults out while trying to reference the machine so I have no idea what shape the x and y drives are in.

On the upside, I have a reasonable candidate for LinuxCNC. 17" Touchscreen panel mount w/serial port.
