Wiring & Interface Connection Notes
- GND – Control ground
- VR – Speed control input. Supports 0–5V analog voltage control. Motor speed increases linearly with voltage. PWM control requires a common ground with the driver board.
- Z/F – Direction control input. Connect to 5V or leave floating for one rotation direction; connect to GND for the opposite direction.
- M – Speed pulse output. Provides 5V pulse signal for motor speed monitoring.
- 5V – Internal 5V output for external potentiometer or switch used for speed and direction control.
- P+ / VCC – DC Power Input Positive
- P- / GND – DC Power Input Negative
- MA(U)/ MB(V) / MC(W) – Motor phase outputs
