AE0016C / AE0011 DC motor controller

[zainka]

Looking for details about treadmill motor controller AE0016C / AE0011 V1.1, for 180VDC motors. Ref. Ebay item 403889373136 as an example (but available everywhere)...

However I lack information about the controller interface on the red connector and the protocol used. Schematic would also be of interest if known.

Thanks in advance.


Edit: Just noticed that there are two versions when it comes to the red connector. There are a 6pin version and a 5pin version. I have the 5pin version.

Did some reverse engineering. Added the schematic (Use at own risk!) but should be enough information to get it up and running.

The interface is most likely just an PWM input, for the moment of unknown freq. ... will test, .... and a reference freq. output for the mainboard to determine status of the motor-driver board. I guess it will output a freq. linear with the current rpm. Did not figure out how they control the elevation motor, but I have no plan for using that anyway.

Tachometer input is a sensor on the motor itself to be connected at JK50 (note, the notation is from the board)
