Eliminating Soft Start on an MC60, MC2000 and MC2100 Treadmill Motor Power Supply for Mill or Lathe

- There are lots of ways to power a treadmill motor when adapting one to shop tools or other projects. One popular option is to use the control board that comes with the treadmill, including the MC60 MC2000 and MC2100. The problem is all of these boards have a treadmill safety feature called "soft start". Soft start requires you to start at the slowest speed before going up to the desired speed. In other words you can not start at a higher speed. There are several techniques to get around or bypass soft start. This video goes over those options.

Daze you’re the treadmill motor king
give the people what they want 😂😂😂
Thanks, Daze! I just clipped R19 on my MC60 for a drill press conversion and now it works like I'd like it to! Set speed, leave it there. Power off, power on--right back where I left it. Took maybe one minute, mos of which was finding my tiny diagonal cutters.
Glad I could help
The capacitor discharge can be hastened by decreasing the value of the bleed resistor if it has one , or installing one between the positive connection of the cap , and a ground trace on the board .
Thanks for the tip
I built a (50mm X 50mm) Picmicro PWM signal controller that has the two momentary PB's , one for start, one for stop. I can stop and start my spindle and retain the same speed setting every time. !
Nice
I just might need to try that idea. I already have a timer that is energized by 110 AC which should eliminate that 12v dc power source.
Thanks for the video
good luck
I’m thinking another option to get around soft start would be to add a 20 amp switch between the motor and the controller. This would provide a way to stop/start the motor without killing power to the control board. To improve on this idea it would probably make more sense to use a 20 amp relay with a light duty switch.
Thanks for the input! That is exactly what people have when they add a forward reverse switch, because said switch must be center off. Once the system is up and running you could totally use the ditection switch to avoid soft start all together , BUT you would still need to deal with soft start the first time you powered up the machine with master power, and you would also probably need to add indicator lights to show you the system is still on even when the direction switch is in the off position. Without indicator lights it would be very easy to leave the system on. This solution while clever is IMHO more of a bandaid than soft start eliminator.
Wall Wart. That's a new one for me.
I’m surprised you had not heard the before. Learn something new everyday
Thanks for this! do you know anything about the Johnson Fitness JDYF20L? Thanks ahead of time
no I do not have any information on that board.
Where does the soft start function live on the board? Is it programmed into one of the chips?
I honestly don't know
Do you know if it is also r-19 for the Mc-20 controller board? Ripped it out of an old lifestyle treadmill that interchangeably used the Mc-60 and mc-20 in its build
I do not know. I would say its not likely but there is a slim chance it would work
MC-60 rev k need R14 blue resistor
Please can some one help need R14
What pins are you using to power your pwm frequency generator off the mc2100 board? For some reason I thought you had used external power for it but realized in this video you have it to the board itself. Thanks for these great videos.
Glad you like the videos... I cover wiring about 13:30 on this video th-cam.com/video/RikeVYxITUQ/w-d-xo.html
The surge at the beginning is going to happen because all if these cheap MCB’s turn on the same way. If you notice the power LED, it will flash once for a split second, then off for a half second, then back on solid. This is the way they are designed for one reason or another….
One way to prevent this would be to use a potentiometer that has a switch on the end of the throw. They also make 4 pole latching push button remote start bottons that have a momentary pin that closes on each press. You may have to add a relay or two in conjunction with this to make it operate as desired for the application…
The downside to these boards is that they are unreliable when you make a simple wiring mistake Or put too much load through it just once. There are also different mc2100 MCB’s that are for 50amps and others that are for 30 amps. The newer boards that have the white main harness connector(instead of red) are garbage compared to the older PWM boards. I’m sure you noticed by now the PWM boards have a much smoother ramp in rate than the mc80 amd mc50 boards.
The more I have messed with this stuff the more I feel using the treadmill power supply is like putting lipstick on a pig. A purpose built power supply even if still DIY is better than a treadmill power supply, but people still insist on doing it so I try to give them options.
updated...treadmill was in flood..prior to flood worked fine...after flood when power on display shows fine but when hit start the motor immediately runs at full speed then shuts off a few seconds later...and this repeats whenever start button is pushed...im thinking its bad mc2100 due to water damage...since the mc2100 was probably in water or got wet.....does this sound logical?
yes that is a bad MC2100
I have used the pulse width generator on the mc2100 and I find the slight delay not too bad on my craftsman 6 inch lathe.
The delay in regards to what? Are you using a relay to eliminate soft start or just the on off button on the signal generator? I ask because I am not sure what delay you are talking about and or how it is related to soft start.
@@dazecars the several seconds after pushing the start button when the motor turns.
@@josephhagler5145 the delay is not an issue it's the soft start that is the problem (not being able to go to the last speed without turning it all the way down first) . Are you using a different signal generator with built in delay to bypass soft start?
@@dazecars I use the one you showed in your video.When I turn it on with the yellow button it goes to the last speed I had set.
@@josephhagler5145 the delay never bothered me either. I just didn't like having to use the on off on the signal generator.
Daze! Do you have a video regarding adding a soft start in a scr circuit?
I've got my setup in a learning environment where I don't have faith everyone will turn down the pot before turning on power. Does this make sense?
I do not have a way to add a soft start. Im sure it can be done but that is above my abilities. Easiest way to add soft start would be to use an MC60, MC2000 or MC2100 as a way to drive the motor.
i would like to use the mc2100 board that came this treadmill for a wood lathe . can i control the speed with a potentiometer using some of the wires that come down from the dashboard , like maybe Black , Red , Blue for instance . thanks Peter
No you can not. Unlike older MC60 controllers an MC2100 uses a pulsing signal from the control panel to control speed. This video (about half way through) shows the signal generator you need to make it work and how to hook it up. th-cam.com/video/RikeVYxITUQ/w-d-xo.html
Instead of turning off the power to the board, whai if you put a switch on the output to the motor?
Thanks for the input! That is exactly what people have when they add a forward reverse switch, because said switch must be center off.

Hi there, the board I have is different to all these, I have to cope with a 5 second countdown and then it starts on the slowest speed. I can then ramp it up in increments on a momentary switch. Any ideas what I can do?
Sounds to me like you are using the treadmill control panel to drive the motor control board, which means I don't have a fix for that. The more treadmill parts you use the more you must deal with treadmill features.
Can you replace the treadmill control panel with a on/off switch and a potentiometer an it work?
depends on the type of board
Can soft start be defeated on the MC80 controller?
you can use the same switch technique as the MC60
