Treadmill motor controller board

[JMacG]

Hi there, I've just joined the forum and this is my first post so here goes.

I've got a motor controller board and DC motor out of a Tunturi T80 treadmill that I'm planning to use in a lathe project. I've built a PWM unit to input a signal but I'm struggling to get the motor to run. There is a 'Relay Enable' input to the board, via the J3 connector (see attached diagram), which is unconnected at the moment, so maybe this might be needed. Does anybody know if this input is needed and what the nature of the required input is (i.e. a voltage input, a ground input, is it a sustained signal or is it momentary?). Hopefully someone can help.

• • Use a multimeter to check if there’s any voltage present on the 'Relay enable' input pin relative to the ground.
  • If there’s a small voltage (e.g., 5V or 12V), the input might need to be pulled high.
  • If it’s at 0V, it may need to be pulled to ground.

I hadn't thought of that, I'll give it a try.
