Can a Fenner servo drive replace a Servo Dynamics?

Can I replace my Servo Dynamics board with this Fenner board? The Z Axis Servo Dynamics SD1525-10 board died on me. I have a spare Fenner SDF1525-16 board.

I believe that the Fenner board supports up to 160Vdc and the Servo Dynamics board is good to 110Vdc. The boards look _very_ similar with the same connectors in the same locations. And I believe that Servo Dynamics may have purchased Fenner at some point (or the other way around)

You can certainly give it a quick try by connecting motor and tach and
seeing if the analog input will drive the motor each way
(a 1.5V cell and a 1K series resistor is a good test source)

Peter, thanks for the suggestion.

Gave it try and didn't let the smoke out

So went fro broke and connected up the 7i77 and was able to move the Z axis with MDI commands.

I suspect that the Fenner sdf1525-16 can have 160 volts as the source. The sd1525-12 can have up to 120 volts. Maybe the difference is that using the Fenner, I may not get as much current so slower rapids (but that's only a guess).
