三、调速说明：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、速度反馈说明：
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、保护及报警Protection and alarm
1、堵转保护、缺相保护，电机被卡死堵转或电机线断开一路则停机报警，红灯快速连续闪烁；
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、过流保护，当工作电流大于设定电流则停机报警，红灯每间隔1秒闪1下；调速信号归零后恢复。
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、过热保护，当电路板温度大于设定温度则停机报警，红灯每间隔1秒闪2下；调速信号归零后恢复。
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、过压欠压保护，当供电电压超出范围则停机报警，红灯每间隔1秒闪3下；调速信号归零后恢复。
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.
