I have a motor control board that has the same speed/startup characteristics as the MC60 (5k pot, zero to restart).

I would like to use it to control its PMDC motor on a CNC mill. For safe and proper operation, my Windows based G-Code controller (Mach3) needs to be able to turn the motor both off and on.

Can the MC60 control be upgraded to soft-start the motor to the RPM's that has been preset by the 5k pot? AC power to the MC60 will be switched by Mach3 through an opto-isolated solid state relay.

 

How about adding a PC controlled relay wired up to the speed-pot to set zero speed at power up that can be energized to shift to the pot set speed? I believe it would work and should be pretty easy to set up.
