The MC2100 treadmill motor controller requires a PWM pulse signal in order to operate. In most cases this is part of the control console on the treadmill itself, not very practical if one is trying to re-purpose the motor for another use. I use the adjustable PWM meter to supply the treadmill motor controller with 20Hz pulse signal it requires and use the duty adjustment to regulate the speed. Motor activates when set to about 8% and max speed tops out at 45% (2500rpm). Power is supplied to the frequency meter by 12VDC ( red and black wires)from the MC210 and the PWM is fed to the MC2100 via the blue wire, the black wire with a white stripe is ground.

Thank you for this! I had a dead treadmill with an MC2100 until I found your video. The control panel isn't available anymore, so I gutted it and replaced it with the PWM like you linked, and now I have a working treadmill again. It doesn't have any features besides on/off and speed adjustment, but it was a $12 fix. Thanks again!
Thanks bro, followed your instructions and got my MC2100 up and running for a lathe conversion. BTW, my MC2100 LTS 50 will run right up to 100% duty cycle for a few moments then over speed shut off ... will run continuously at 90%, 4000+ rpm. Motor is a 130v, 4.5 hp unit out of a Nordic Track.
Good job! I have a lathe conversion in my future as well.
This is awsome thank u very much!
20 hz is frequency key to make it work!
I thank you for doing all the hard work. I have had a MC2100 for years knowing that sooner or later, someone would have a good solution. I have tried to build things from what people have shown and I couldn't get them to work. I purchased one just like yours only with 6 pushbuttons and I burnt it up. I figured out why I burnt it up, the model that has 6 pushbutton controls on it and the points of connection are not the same as yours from what I could tell. Where yours is set on 20, this one breaks it down into thousands positions as well, I had to put mine on .020 and I ran mine up to over 90% speed until it cuts out. I had to magnify your pictures to figure out the hook-up and I also went to "sons of inventions" site on running the MC2100 and at almost at the bottom of their site, there is a schematic and list what all the wiring is, IE; the 8 pin connection, the wire on both ends are black and are grounds, the red is your voltage and the blue wire is the pwm connection. Thanks again for doing all the good and hard work.Tim
tim smith thank you for the kind words. Sorry for the lack of detail in the video, I’m an old guy and this stuff is all new to me. I was hoping that it would help out fellow “MacGyver’s” by at least sending them the right direction. Since posting my video another viewer mentioned another pulse code generator that also has a built in on and off switch. You are able to start and stop without changing the speed setting. I ordered one but have not tried it out yet. Perhaps a new future video !
You are ALL my saviors.........Thanks Dave from "Downunder"
Thank you. Based on another video I got the PWM with the dial but could not figure out what frequency.
2500 rpm is plenty for that motor's efficiency. I've made the dual 555 IC boards that allow a higher % of max and speeds above 2600 rpm which these motors aren't designed for. bearing quality, so-so balancing vibrations, efficiency etc. So for the price and hassle dialing in the 555 circuits these devices work great.
This right here is what I have been waiting for. I have had this 2100 sitting around because I didnt know how to built the circuit it took. Tha,k you for sharing! Also please show how you have it wired.
Power is supplied to the frequency meter by 12VDC ( red and black wires)from the MC210 and the PWM is fed to the MC2100 via the blue wire.
Thank you so much for the video. I got my set-up working without releasing the smoke!! :-)
Thank you for the comment, glad to hear it worked for you.
For those having trouble getting the unit to work. I bought the controller version with the knob and on/off button. I found that when board is powered on, the unit (signal) *must* be off (configurable); then when turned on it starts at the duty% last used. For the unit in the video, perhaps the duty% must be zero first? Also, the only frequency I found that works is 20Hz (200, 400, 800, 2k, 20k all failed). Also, I was able to reach ~100% duty but the motor cuts out. At ~90% duty, motor is at 100VDC, the "continuous duty" rating of the motor and is stable (~6200 rpm). Motor is Proform Treadmill 2.85hp@130VDC; 1.75hp@100VDC continuous duty. Board is MC2100WA Rev B.
Yes, 20Hz is the only frequency that works. Great idea to use the controller version with the knob and on/off functions, I do need to reset my controller back to zero on the Duty % and then raise it up again as needed. The initial test was just to try to get the darn thing working. The next one I order will certainly be like yours. Thanks for the heads up !
will this controller work for mc2100 baord i have exact same motor as you from a pro form treadmill 2.85HP 1.75HP cont ...really anxious to get this going ... www.ebay.com/itm/Square-Signal-Generator-1-150KHz-PWM-Pulse-Frequency-Cycle-Duty-Adjustable-Meter/312690277939?hash=item48cdcafe33:m:mDN4M2CcoqxdWPGwhTdYxFw or what about this www.ebay.com/itm/Signal-generator-PWM-pulse-frequency-duty-cycle-adjustable-module-lcd-BRPC/174122831196?hash=item288a878d5c:g:zp4AAOSwCgtcQtp3
@@shelby50411 As long as the frequency can be adjusted to 20Hz you should be fine with either one. I would go with the one that has the on/off button with the rotary knob.
thanks i dont see the purpose of the on/off switch since the main toggle switch to the power supply will turn on and off correcT?
@@shelby50411 The main power supply will turn on and off but you will likely have to reset the speed back to zero and then turn it up again ..The on/off button on the PWD will turn the motor on and off without changing the set speed
I beleave you change the value of the ceramic resistor this cuts out you speeds. Just like an electric industrial train. Look up the old speed controls from rc cars in the late eighties it was basically a potentiometer total open case ran through A ceramic resistor todisapate the heat. Same scenario great stuff.
I discovered that one of the solder connections on that ceramic resistor had come loose and vibration on the workbench was causing the motor to cut out. I re-soldered the terminals and it works just fine now. Check out my other video with the upgraded PWM. Thanks
Thanks for the video! this is exactly what I was looking for. :)
You’re welcome , glad I could help.
So glad to see this valuable info. Who shoots in portrait, though?!
Thank you for this. I'll be watching the entire thing.
Hope you find it useful.
I’m an old guy and not too savvy at this TH-cam stuff. Just thought someone else out there could use this info. Cheers.
Does anyone know what that red 8 pin connector is? Its really hard to find a matching one!
Hello,
First of all... great job for your videos :)
I have the same card... and when I try to start the treadmill... there is a "flash" on the card near d12 and d17 components.
Did you ever have this kind of problem ?
Regards :)
Great video!
Thanks! Check out my other video, perhaps a better explanation.
Someone needs to have a video of showing the voltage meter wiring How do
I just acquired a couple of these controllers and am trying to get them to work and this is exactly what I'm looking for. But could you please show how you ran the wires. What went were? And what is connected to the two black wires going off the back? Is that a switch or a fuse?
Anthony, The two black wires out the back are just a loop for the 15amp fuse that protects the motor board. There is also the main power switch. The fuse and power switch are hooked up the same way they came out of the treadmill. The purpose of my video was to show that you can eliminate the treadmill console panel and replace it with the PWM device to get that motor control board working again.
Do you know what type of capacitor is C28 ?
I have the same motor, a same driver and purchased the same PWM generator you are using. But I can't get it working. My driver pinouts are as follows:
Black - Ground (to PWM V-)
Red - 8-12 VDC (to PWM V+)
Green Tach. (n/c)
Blue - PWM input (to PWM output)
Orange - Incline Up (n/c)
Yellow - Incline Down (n/c)
Violet - Incline Sensor (n/c)
Black - Ground (to PWM Ground)
I get no motor operation. However, the system works fine when I connect the original treadmill control panel. Any ideas?
You have the pinouts correct. did you set the PWM to 20 Hz ?
I understand this is an older post, could you please describe how the PWM generator connects to the mc2100 board - pin to pin connections? I know there are 4 terminals on the PWM box but 7 or 8 wires on the connector on the mc2100 side. I probably need a sort of paint by numbers explanation, thanks so much.
Wiring description is shown in the video title. Check out the second video I posted with the upgraded PWM and it will give you a more detailed wiring explanation at the end. Thanks
2 questions,
1) does the PWM module need to be set to 20 Hz?
2) why is there a blue wire going from your motor to A-?
Yes, 20Hz is the only frequency I found works. The blue wire is part of the thermal overload circuit that is built into the motor, power runs in series through it. Some chose to eliminate that protection and just use the black and red wires to the motor.
Check out part 2

@@makerofthings2472 I saw pt 2 first and got the module with the I/O button, thanks for that tip. I recently discovered my salvaged motor and MC both work at 20Hz, so thanks again!
In that board a compaant named ac24016 .can u say the component name plz
I will take a pic of speed sensor and post . not sure if you can hot wire(jumper) to high limit or not.
shauntx2197 I do not have a speed sensor hooked up on this board. If you check out my updated video you will see that the problem was being caused by a loose connection on the resistor. I can get full speed now without any problem. Thanks
MakerofThings247 do you happen to know if a signal generator would also happen to work with this board as well??
great info, My MC2100 has a speed sensor that is magnetically controlled it will give an error if not hooked up . that might be the limiting issue. at 45% what is your measured Dc output?
So ive had mine working for months great. then i left pin in my lathe turned it on and stalled motor! Something kicked out? Now it starts to spin and something kicks it out? Any ideas. Plugged a different motor in same results so its either pwm or mc2100?
My guess is that some safety limiting switch on the mc2100 has been cooked. The PWM is relatively cheap to replace, perhaps try that.
@@makerofthings2472
So i had already ordered the pwm and agree for $12 i did try that same outcome. so probly the board any idea what exactly cooked? Its weird it turns the motor for a split second then kicks out?
@@jayhansen5544 sorry you’re still having trouble. Unfortunately diagnosing the mc2100 is beyond my abilities. My video assumes a properly functioning board. There are other ways to get dc treadmill motor working without using the mc2100 but you will lose soft start.
hi, i try to repair my board. r22 is burnt and i can not read the color code on it. you seem to have the same board as mine so can you take a look at it and tell me the R22 value please?
Erick Dupuis, I see white, black, red and gold so....90k ohms +- 5%
Thank you very much
Same set up mine not working. My pwm control not lighting up or working
Perhaps your motor control board is defective? The PWM unit requires 12V DC to work
I was able to get the pwm to light following your wireing dia. up but no movement of the motor now my 2100 board looks a little different from your board maybe mine's a newer model and that could be the problem? Your thoughts??
oGt 92fromthe1stEp , Have you set it to the correct frequency? You also need to turn the duty cycle down to 0% and the raise it up gradually. The motor should kick in around 7 or 8 %
Yes sir
Yes sir i starded at zero then worked up and nothing but i just now realized i dont have my linear actuator hooked up to you think that could affect sir
@@ogt92fromthe1step9 No it shouldn't matter
Did u figure your board out mine is doing same thing lights up but motor dont move?
Probably the easiest MC2100 pwm controller mod
Thanks!
from the board to the controller could you list the color code to controller.. assuming red is 12v and black is neg. blue is what and blk/wht is what
Red is V+ , black is V- , blue is PWM signal , black with white stripe is ground.
MakerofThings247 thanks
How did you find the frequency?
Online research suggested 20Hz I tried it and it worked.
There is a pot on the board that sets the high rpms.
Thanks, good to know if I should need to crank up the RPM .
Can you elaborate? Does it affect the PWM generator ?
But you are not explaining the important stuff. Why?
Not sure what you mean. I made a follow up to this video, the link is in the description. It may have a better explanation of how to hook it up for you.
