Generating the control signal just takes a few ICs. Then creating the PWM part is another couple. Calculating the speed and driving the display are the hard parts. But just making it run at a constant speed set with a knob on a pot is not big and does not require a processor.

i want to use it as a treadmill not a chainsaw...

 

OK, it is the rest of the system that is the big deal part. I don't do treadmills and so I am not very familiar with all of the features and functions involved.
Many of the previous postings in this forum have been about re-purposing treadmill motors for other applications.
Adapting a treadmill motor to a safe chainsaw would be quite a challenge..

 

Well, it seems you can't measure the panel's communication signal.
Now you can only remove the EM78 and use UNO R4 to control the motor. Send PWM signals and receive safety signals. Please note that you need to confirm that the power supply voltage and current are sufficient to support UNO R4 operation. But I don't recommend this.

Unless you can provide a clear schematic or photo, only the manufacturer can help you.

 

By the look of the machine on their website, it has a fairly sophisticated operator panel, I would be hesitant to try and produce a motor controller without having details of the operator interface processor.
One will have to communicate, each with the other.

how I could measure the panel's communication signal?
I try for days to trace and write clearly with KiCad the motor pcb parts so I can help people that know here to help me with the right connections od UNO R4 with the board to control safely the motor treadmill...
If you know some code of arduino to try send signals on the PCB would be so cool to try...
I would apreciate any other help you could provide me as informations...
Thanks in advanced

 

I also want to simulate the control speed for a large dc motor, I made a circuit for a 36 volt motor with a mosfet, a bipolar transistor and an arduino and I managed to regulate it, but now I need to use a motor of about 180V at 1000 watts

 

A MC2100 TM board would work, but only uni-directional, do you need bi-direction?

Hello, I want to control uni-directional speed control of DC motor with Arduino I made a circuit with amplification through a bipolar transistor for 36v DC motor, because my mosfet opens at 10 volts, can I use this chip instead of bjt transistor? I need to control the speed of a 220 volt 450 watt DC motor

 

If you use PWM of over 2-3 Khz then I would go with a Mosfet.

Arduino nano's pwm frequency is about 490 hz can I use MOSFET?

 

Yes Mosfet is OK.
I do not use Arduino, but how come it is limited to 490Hz?

 

Arduino nano is limited to 490 Hz (pins 5 and 6: 980 Hz)

 

Seems overly restrictive, but if that is only what you can use, then the BJT should work for you.

 

I connected the Arduino pwm bjt output and made a mosfet switching circuit, but I made it for 36v DC motor , now I want to control 220v 450W DC motor speed, i want to use MC2100 for MOSFET drive with half bridge topology. In this pic schematic of 36v DC motor control

 

Not quite clear how you want to use the MC2100?
How does that configure into the Arduino?

since I dont find a solution with my motor board Iam thinking to buy an MC2100 motor board but seem there are many similar models that start with MC2100-something... since u seem to know a lot about this board can u suggest me one that can accept 220VAC 50 Hz from the wall and outputs 180VDC for the treadmill motor? I want to use it to fix my treadmill and connect an arduino to control it or anyhing else u suggest me that would work... Thanks in advance my friend

 

Where is the TS that they get 220 volts DIRECT CURRENT from a wall outlet?? I know that in the UK there is 220 volts AC, 50Hz, but not DC. OR is that a typo sort of error??

Yes there are MC2100 that accept 230vac mains supply, I don't normally see them in N.A. but I believe the circuitry is very similar, for stand-alone operation , you require a 20Hz PWM signal into the HD2 pin4 strip.
I built some small Pic based boards for stand alone control, you should be able to achieve the same with Arduino.

so sorry... it was a typo... wall voltage is 220vac 50hz
