1. VCC : Connect 12-30V power supply ( Refer to the working voltage of the motor, general 24V )

2. GND: Ground wire

3. CLK : Control signal (Connected to pulse input )

4. DIR: Direction control signal ( Floating forward, ground reverse )

5. ENA: Connect to enable signal ( Default enable, grounding stops working )

6. P2: Connect one phase to the motor on each side ( Refer to the motor parameter description, the motor is divided into two phases AB, pins 1 and 2 are connected to one phase, and pins 3 and 4 are connected to the other phase. )

DIP switch {ON (1) / OFF (0)}:

1. Div1, Div2 control pulse frequency division

(1) 00: 4 subdivision

(2) 10: 8 subdivision

(3) 01:16 subdivision

(4) 11:32 subdivision

2. Ctl setting control mode, open-loop / closed-loop

(1) 0 : Open-loop mode

(2) 1 : Closed-loop mode

3. AC setting calibration

Turn the AC to position 1, and turn on the power. The LED blinks 3 times to start automatic calibration. The motor shaft rotates counterclockwise for one cycle and then clockwise for one cycle. The system automatic calibration complete and the LED continues to flash. The AC dial returns to position 0, and then restart power.
