Manual control of MC-2100 treadmill motor controller?
There are oodles of "how tos" on adding manual speed control to an MC-60 motor controller board. I'm trying to find something similar on the MC2100 -

but nothing turns up. The treadmill I "re-purposed" gave me both the motor and 2100 controller, and I'd like to use the 2100 if it's not too tough to mod for someone like me who has not much electronics knowledge. It's going on my REAL low tech South Bend 9C if it matters.
Thanks,
Andy

Manual control of MC-2100
Hi all. New to the forum and am not an electronics expert. I found the info on this thread very helpful in working through a solution for using the MC-2100 controller board with a treadmill motor. The only thing missing from what I can tell was the need to set a static frequency of the modulated square wave being sent by the 555 timer. Attached is the circuit I used to finally get by Mc-2100 controller board working without the original treadmill console.
I used a 556 dual-timer. The first half of the timer circuit set the frequency. You can tell you have success when the MC-2100 controller board begins to flash. My understanding is that the board will not recognize the signal until the frequency is set correctly. So if the LED is not flashing, the controller is not going to work.
the second half of the dual timer modulates the duty cycle or width of the pulse (as shown earlier in this thread).
Again - I would not even classify myself as a strong electronic hobbyist. So I welcome any modifications, corrections, or suggestions.
I just wanted to share what worked for me.
:D
manual control of mc-2100
Hi Dan,
I'm trying to reproduce the circuit to provided above using the same control board. I don't have the 8 pin wiring harness, however, so I can't interpret the color-coded instructions. Could you please list the order the the wire colors from top to bottom if you have this information available? Thanks.
Re: Manual control of MC-2100 treadmill motor controller?
I have a MC-2100 and treadmill motor that I'd like to use on my milling machine.
Is anyone willing to sell one of these PWM circuits or do you know where I could purchase one ready to use?

Hi.. I built this circuit but cant seem to get it to work right. It pulses until c1 is charged then stops. if I pull out c1 and hold the leads together to discharge it then put it back in it pulses againg until c1 is charged again. I've checked my wiring several times and can't find anything wrong with it... Any suggestions?
Re: Manual control of MC-2100 treadmill motor controller?
I have a acquired a MC2100 for experimenting with a 8pin Picmicro to drive it.
Can anyone confirm if it runs without the rpm sensor, If not can anyone shed light on the resolution and nature of the tach.

Re: Manual control of MC-2100 treadmill motor controller?
Not quite finished the pic version but evidently the MC2100 uses a L.F. 20 Hz PWM command, there is some circuits out there, I just want to keep the component count down using the pic.
Those in the link are generally to high a PWM freq.

Completed the 8 pin Picmicro version for the MC2100 , Two P.B. implemented for Start and Stop, a start will run the motor wherever the pot is set to.
PCBway made up the circuits boards for me.

Al are you selling your 8 PIn Picmicro boards ?
tks

Re: Manual control of MC-2100 treadmill motor controller?
I could send you one, did you want a populated or unpopulated, with just the Pic processor?
