I have a small Knee mill (Clausing 8520) that I plan to power with a PMDC treadmill motor rated 2.65 h.p. @ 130VDC. Below are a few of my questions.

Any ideas on how to modify a MC-60M control board to reverse direction? Or, is it best to just use a DPDT switch/contactor between the controller and the motor? Does the choke have to be on the negative(A-) side of the motor circuit?

Anyone know how to disable the soft start/stop feature?

Finally, what happens when you clip RPS3?

Thanks,
PK
