Reebok IRun treadmill motor control board

Hi has anyone had any experience with these I currently have two boards both no dc power output I know the motor is good as I’ve tested it with nicads , I’m under the impression. It’s. Pwm at low voltage 1.5v to 5v. From the display unit and this drives a fast fet to generate 0-200 vdc for the dc motor dhas anyone investigated this and can you give me pointers to look for ?

What is the model No on the board or post a pic, if it is the same as the MC2100's then it requires a PWM 20hz signal to control, they are opto isolated input so the voltage in can be tailored to the Opto in current.
Max.

It’s from the iRun , I don’t think it’s optoisolated though. Part no of the control board is JD-230E/E if anyone has a circuit diagram I’d be very grateful.
