mill conversion

Hi everyone i have been putting this off for a long time as i know little about electronics.I have decided to convert my small mill to belt drive with the use of a treadmill motor.I have purchased this power board my potentiometer has three blue wires from what i understand they are wiper hi-lo but it all so has two black wires but i cannot figure out where they go.I believe they are to power the machine up as that is what happened when it was used originally.I all so have a E-stop button with 4 connectors on the back any help would be great.

Now … a photo of your potentiometer would be useful, Andrew

Hi Michael here are some pics.

I all so have this potentiometer as well

Thanks, Andrew

I would assume that the two black wires are connected to a built-in switch

… a few seconds with a multimeter should confirm.

I agree because the potentiometer has a click sound when rotated but where do these wires go ?

Hi
The drive you linked to has no facility to use a potentiometer with a switch. The potentiometer with switch will work if you just ignore the switch wiring. However you will loose bit of mechanical and electrical travel and thus control at the low speed end of the range. The potentiometer without switch would be a better choice.

Thanks Robert can you tell me what goes onto the four connectors on the stop button could i use that as the power button

As per Michaels comment. The 3 tags on the paxolin together will be the pot the other 2 will be an on/off switch. Noel.

Thanks Noel i get it now but dont know what to do with the four connectors on the stop button

Andrew,

Did you spot this PDF lurking at the bottom of the page that you referenced ?

Excellent is the DPST switch the switch i am referring to with the four connectors and does it matter which goes where as my switch does not have any symbols saying what's what

I see now i will need a separate on/off switch as well as the stop button

What about this one

The switch in your photo appears to be of ‘open construction’ … so it shouldn’t take long to determine its connections.

DPST = Double Pole Single Throw

If you're unfamiliar with the terminology … this should help: **LINK**
