Does anyone have any information on the MC-20 motor controller made by Samsung. I have one that came out of an old low end treadmill. It is similar to the MC-60 in that it has a 5k pot as the speed reference and its an SCR, not a PWM. My assumption is that is older than the MC-60. I tested it on the bench and it works fine. However, I'd like to disable the "safe start" feature so I can use it on a small drill press. I've done this on the MC-60 but I can't find any information on the MC-20. An help would be appreciated.
