General Electric HIAK servo drives

Hi all,

I have a Wadkin V5-10 cnc mill with GE mark century 2000 control. The machine is dated around 86-89 I think.

I am looking for information / datasheet / specs / pinouts on the General Electric HIAK dc servo drives. Exact models are 3N2100SP104C1 and 3N2100SP104E1. I know they are rated for 51amp 90vdc but that's about it.

Hopefully someone has some experience with these drives? I am considering a retrofit using Dynomotion Kflop & Kanalog but I'm not sure if the HIAK drives are -10v to +10v input. Or which pin does what.

Many thanks,
Jim
