Instruction for WS-3H15high-efficiency brushless dc motor drivers

CHARACTERISTICS:

1.DC voltage15VDC-50VDC

2.PWMFrequency over12KHZ

3.Input signa is compatible with TTL

4.The most driving current 15A

5.size:118*75*33 mm

6.weight:0.27Kg

NOTE:

1.+AT,-AT portis outsideDC power supply

2.U port for motor U pin

3. V port for motor V pin

4. W port for motor W pin

5. +5V for sensor power

6. GND for sensor or control GND

7. HALL A is sensor A input

8. HALL B is sensor B input

9. HALL C is sensor C input

10. CW is for motor forward direction,active low

11. CCW is for motor reverse direction,active low

12. AD for motor speed(0-5V or 0-10V)

13.BRAKE port is braking input end,low level.

14.The driver has ACCpotentiometer forstart-up accelerationc, accelerating time from 0.1s to 3s, To adjust accelerating valuet with power off. Out-factory setting 0.1S.

15. SUB SPEED potentiometer is forauxiliary rotate speed adjustment.Different motor parameter need below adjustment.DA input voltage adjusted to 5V,ifmotoringspeedis not the highest speed, To rotateSUB SPEED potentiometerclockwise until motor reach to the max speed.

If DA port is less than 5V,motor has reached the max speed, DA port adjust to 5V now.To rotateSUB SPEED potentiometeranti-clockwise until motor reach to the max speed.
