Boss 8 to Mach Conversion Help

Everything seems straight forward except servo drive choices. The stock current drivers are NC400 units with 30 Amp capability. The factory Power Supply puts out 100 Volts DC and I would like to reuse this in my conversion. 100V @ 30A is more than a Gecko drive can handle. I looked at Rutex, there inventory seems to be low, makes me a little nervous. They have a board (R991H) that looks like it will take step/dir and the encoders and put out a +-10V signal to the stock NC400 Current Amps. Anybody use these? How about the R90H? Any other low cost servo drives out there? I am an electrical engineer (and a technition before that), so I "Aint Sceered" to try ideas.

I also need the encoder pinout, they have 10 pins (5 twisted pairs, all the same color in the cable).

Any help would be appreciated.

Thanks,
TurboStew
