I have done google searches as well as part searchers for the ALT 6330 board, I have not found anything.
I also contacted SOLE fitness who uses the board (also Spirit fitness), and they claimed they didnt have such information when i spoke with both sales and the technicians. Not sure if they dont want people to take trade secrets or what? The board is very similar to the MG5220 and 28 something that controls other treadmills.
There is another board in the console that sends a signal to the motor driver board, so unfortunately that complicates it. If I could control the motor alone I would, however not sure how difficult it would be to control a motor with an arduino and not blow my computers circuits considering the motor is 90v 30amp. (I know I would have to create a secondary board).
What type of information is needed? I cant make any calls today because they are not open, but hopefully I will find something. I believe I will be purchasing my first Arduino today so hopefully soon I will be out of theoretical, to practical and experimental mode.
This project has been a bit overwhelming, but worth it in the end, I have learned a lot about electronics, soldering, etc. Hopefully I will be designing my own boards soon.
