I have an MC-70 harvested from a treadmill. I am hoping to use it to power a milling machine.
I have it set up on the bench and it runs as expected when I put a 10k pot as a voltage divider on the “W-H-L” terminals. Two of the features I want to incorporate are a “pause switch” and a “jog” button. I have tried to do this by putting in a switch in the “W” terminal and a button to momentarily bypass that switch.
Issue is:
When the voltage is cut off from the “W” terminal the motor keeps running, at the last “commanded speed”
I would have thought the voltage going to zero on the wiper would cuts the power off. It doesn’t....
Is this part of a soft Start circuit? A bit of logic built in to prevent a sudden stoppage of a treadmill? If so can it be defeated?
