The Nema 23 documentation says the 4 colors should be red, black, orange, and yellow. Does anyone know which of my four motor wires are A+, A-, B+, and B-?
I finished mounting the 3 motors, and I have a Gecko g540, and a Keling 48v 7.3amp power supply. I'm ready to start connecting wires! ya! If I guess wrong, is it bad to connect the wires like:
B-, B+, A+, A-. will anything break? or will the motor just run backwards or something?
