1982 Matsuura MC-500v Retrofit

again - I think I just grounded pin 1 to enable the drive..

Ok.. I see that now. Thank you

Then I should just need servo on (pin1) connected to ? voltage and the drive should enable and I can send it a small voltage from my bench top supply to check movement.

Right now if I send voltage to the analog then the IN led will turn on showing signal in. No movement though so seems like the drive is not being enabled.

I would not apply any voltage to the drive enable pins, I'm pretty sure you ground them to enable the drive

Grounded (pin1) and then applied voltage to the analog line and I can move my z axis both directions with my bench top supply.

what do the lights on the drive indicate?

sam

There is a green power light and then when I apply voltage to the analog +/- in the IN red led come on and the axis moves. No other lights at all.

Should there be?

Updated my reply to PCW.... I put not in there on accident. I meant to say I CAN move the axis.
