GND | Power supply negative electrode | |
U | Motor connection | Motor line U phase |
V | Motor line V phase | |
W | Motor line W phase | |
VDD | control single | The positive pole of potentiometer |
VS | Speed regulation signal input | |
COM | The negative pole of potentiometer | |
EN | Speed feedback signal output | |
RVS | Potentiometer,reserve(Apply to function extensions) | |
FG | Output single | Work enable input, connect COM port to work |
ALM | Alarm signal output | |

三、調速說明：Speed regulation description:
Mode 1：Add 0V-5V analog signal to port VS for speed regulation
Mode 2：Add 0%-100% duty cycle PWM signal to port VS for speed regulation,PWM Frequency domain: 1Kz-20KHz
Mode 3：Add potentiometer to port VDD VS COM for speed regulation,10K is recommended for potentiometer.
四、速度反饋說明：
Port FG is Speed signal feedback,
For 8-pole motors, FG frequency * 30 = current speed.
For 4-pole motors, FG frequency * 60 = current speed.
五、保護及報警Protection and alarm
1、堵轉保護、缺相保護，電機被卡死堵轉或電機線斷開一路則停機報警，紅燈快速連續閃爍；
1. Locked rotor protection, motor disconnection protection, if the motor is stuck or the motor line is disconnected, the motor will stop and give an alarm, and the red light will flash quickly and continuously;
2、過流保護，當工作電流大于設定電流則停機報警，紅燈每間隔1秒閃1下；調速信號歸零后恢復。
2. Overload protection: when the working current is greater than the set current, stop the motor and give an alarm, and the red light flashes once every 1 second; After the speed regulating signal returns to zero, the motor returns to normal operation.
3、過熱保護，當電路板溫度大于設定溫度則停機報警，紅燈每間隔1秒閃2下；調速信號歸零后恢復。
3. Over temperature protection: when the temperature of the circuit board is greater than the set temperature, the motor will stop and give an alarm, and the red light will flash twice every 1 second; After the speed regulating signal returns to zero, the motor returns to normal operation.
4、過壓欠壓保護，當供電電壓超出范圍則停機報警，紅燈每間隔1秒閃3下；調速信號歸零后恢復。
4. protection beyond the scope of power supply voltage，when the power supply voltage exceeds the range, the motor will stop and give an alarm, and the red light will flash 3 times every 1 second; After the speed regulating signal returns to zero, the motor returns to normal operation.
