Thankyou for the video, but I need to know which colour from the foot pedal wires you connected to the middle of the three pins on your potentiometer. On the video, I can only see a green clip from a test lead. As you can see on my attached picture, I have one black, one green and one red wire which connect the foot pedal to the control box. Did you connect the black wire to the green test clip, or one of the others?

black=left potentiometer pin
green=middle
red=right

Thankyou very much for your help. Now I got my motor to work, and it has a stable speed. Can I now use the potentiometer to control the speed instead of the buttons on the control box in order to regulate the speed without loosing force on the motor?

No problem. Yes you can control the speed but make sure you select 4500 as your highest speed and 500 as your lowest in the settings. you will also have to always return the potentiometer to 0 everytime you turn it off otherwise it wont start.

Yes, I have the same problem regarding turning to zero. My motor starts first when I have turned the potentiometer half the way around (in the middle position), so I have a very narrow scale for the speed regulation. I have tried with a 1K pot. Will I get a wider scale if I decrease this value from 1K to f.ex. 220 ohm?

25k will work fine, if yopu want a finer scale you can use a multi turn wire wound potentiometer
