A small tip:
1000CPR stands for 1000 Cycles Per Revolution. It’s a specification used with rotary encoders, specifically referring to their resolution.
Overall Size
Motor 4 Leads Connection: A+(Black), A-(Green); B+(Red), B-(Blue)
Encoder 8 Leads Connection: A+(Black), A-(Blue); B+(Yellow), B-(Green), Z+(Brown), Z-(Grey), 5V(Red), GND((White)
If your drive controller don’t support Z signal, then you can leave Z unconnected.
