I think it's a good candidate for > conversion. The servo supply transformer is three phase Well, that's a pain, for sure! I think a beefy step-down transformer might do the trick. Do you know what the DC bus voltage is supposed to be? 170 V might be a bit high for many servo amps, though. Perhaps a bucking transformer at the input could get the DC bus down to about 120 V, which should be about right for the SEM motors. > The amps are velocity mode with +-10 inputs.

I have some info from the theory manual on the R2E3 (BOSS 8), but it is not QUITE enough detail to be sure about these. > There is nothing unusual about the machine and I don't know of any > gotchas.

After using EMC2, I could NEVER go back to the punched paper tape world, even the simulated paper tape world with a PC and serial link or BTR. (I had a home-made BTR setup on my Allen-Bradley 7320 control, and while it was certainly "functional", it was a TOTAL pain. The version of the executive I had didn't have any editing or download capability on the control, so EVERY program change, even one digit, had to be edited on the PC and then re-sent (by drip-feed) to the A-B. Moan!)
