Refit Kitamura MyCenter Zero

Hello all, I've been lurking and reading for awhile. Now I need some advice. I recently purchased a 1989 Kitamura MyCenter Zero With Fanuc O Mate and Sanyo Denki drives (BA030-04) and servos (65BM004) with a Z axis fault. I was told it was the encoder. The problem was the brake not disengaging. Once that was fixed the Z axis drive faulted with no load, the solution per the manual is to replace the drive.

Instead of fighting this thing through all the problems it may have that I haven't even gotten to yet, I would like to do replace the axis drives and steppers and use LinuxCNC as the controller. I would like to keep the spindle servo and drive so that I can use it to ridged tap and index for tool changes. I found this thread regarding setup of the spindle. forum.linuxcnc.org/30-cnc-machines/29530...center-spindle-motor The 12 position ATC and its controls can wait for phase 2. My main goal is to get the axis, spindle, and drawbar operational.

Here is the hardware that has stuck itself in my brain.
Panel mount touchscreen PC (need to load Linux and check latency)
Mesa7I76E
Clearpath SD servos on X, Y, and Z

Optionally I could reuse the amplifier and servos that work with a Mesa 7I77. Any suggestions on a reliable amp for use with the stock servos?

What would you do? Any help is greatly appreciated.

I have built a couple of small, stepper driven, CNC machines before and ran them with Mach3. I was very disappointed in the control and rigidity. I have installed linuxcnc on a couple of computers in the past to try it out. I have never ran a machine with it.

I tried to link some photos of the machine but recived an error stating I have too many links. I'll try more once I prove Im not a spammer
Bad Z Amplifier

Spindle Amp...I think

Thanks for the help.

The spindle is 230v 3 phase AC 2.2 kw continuous (3.7kw for 30min). It is a brushless servo with position control through a D/A converter.

The axis motors are 3 phase brushless servos. 230v

The axis encoders use A+-, B+-, C+-, U+-, V+-, W+-, 5V+,5V-.

I will work on getting the manual scanned.

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.
