Wiring diagram:

| Signal | Terminal | Content | 
| Output signal | ALM | The motor or driver controls the fault signal output signal, which
is normally 5V, and the level is 0V when the fault occurs. | 
| SPEED | Corresponding to the operating speed of the motor, the
corresponding pulse frequency is output. With SPEED-OUT, the speed
of the motor can be calculated. The calculation formula is: N(rpm)=(F/P)*60/3 F:Output pulse frequency(HZ);P:Motor grade logarithm;N:Motor speed For example: motor 4 pole F=1sec/2ms=500Hz N(rpm)=(500/4)*60/3=2500 | |
| Control signal | BRK | When the BRK and COM terminals are disconnected or the high level
is input, the motor brake stops. When the motor is shorted or low level, the motor runs. | 
| EN | When the EN terminal is disconnected from the COM terminal or the high-level input is input, the motor stops slowly. When the short-circuit or low-level input is used, the motor runs. | |
| F/R | When the F/R terminal is short-circuited with the COM terminal or the high-level input,the motor rotates forward, and when the short-circuit or low-level input is used, the motor reverses. | |
| COM | Public port (OV reference level) | |
| SV | ①external speed potentiometer ②external analog signal input ③ pulse frequency input | |
| VCC | External potentiometer interface | |
| Hall signal | REF+ | DC brushless motor Hall signal power supply. | 
| HU | DC brushless motor Hall signal HU. | |
| HV | DC brushless motor Hall signal HV. | |
| HW | DC brushless motor Hall signal HW. | |
| REF- | The DC brushless motor Hall signal is grounded. | |
| Motor connection | U | DC brushless motor U phase. | 
| V | DC brushless motor V phase. | |
| W | DC brushless motor W phase. | |
| Power connection | DC- | DC power input to the negative pole. |
