The encoder signal is messing me up a bit ...
Hohner (brand name) incremental encoder part number IN88AECS-L7AC-1000, through shaft, diameter 5/8 inch.
Enc = encoder male terminals on round connector
Ctl = 5 pin male header on board
What I think the pinout should be:
Enc - 1 = GND = White/blu -> White/blue -> far left or 1
Enc - 2 = PWR = blu -> blue -> 24V
Enc - 3 = A = Brn -> 20K -> 5K -> GND. A signal from between 20K and 5K resistor -> middle or 3
Enc - 4 = B = White/Brn -> 20K -> 5K -> GND. A signal from between 20K and 5K resistor -> far right or 5
So - testing with a 12V source (the power supply can be 9V - 24V DC)
Feed PWR +12V and GND 0V
Output signal A is a square wave about 0 -> 10V.
Output signal B is a square wave about 0 -> -10V?
Paul - if I drop the A signal to 0 - 5V and the B signal 0 - -5V ... is the board going to work OK or do I need to shift the voltage on the B signal to positive?
I've never scoped an encoder before, so I don't know if this is a typical signal.
When I went through the instructable it appears that the locked rotor test and tune can be done without the encoder connected .. so I will try it!
