The motor driver board attached in the picture with the first post is the board. I have not been able to pull the schematics for it online, the one in white is one that I found that resembled the board in a google image search.
The white pins are:
1) S/W - Which i am assuming is the safety swithc which is either open or closed. 2) Down - This is the down for Incline motor 3) Up - Up for incline motor 4) VCC - Commons??* 5) Fast - from the upper controller to motor - Increases speed of motor. 6) Slow - Decreases speed of motor 7) GND? Unknown 8) SPD Unknown 9) SPD Unknown 10) VR-1 Unknown 11) VR-2 Unknown 12) VR-3 Unknown
The black and white schematics show that the PWM signals is sent between 0-5volts and the signal interval is 51ms.
The motor itself is 90v 30amp rating.
Other than that I do not have much information. I was assuming that the 0-5 volt information was enough. What other information is needed to make a conclusion? Also I was more curious as to which Arduino would allow me to send multiple PWM signals. I am curious if the 2 (SPD?) buttons from above have anything to do with speed and/or if they are the additional speed switches as there are 2 on the upper control board. I have called the company and spoken with them, they do not have schematics that they offer. Is there any other way to find out?
