二、技術(shù)參數(shù)Technical specification

二、端口描述Port definitions：

三、調(diào)速說(shuō)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(shuō)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(hù)及報(bào)警Protection and alarm

1、堵轉(zhuǎn)保護(hù)、缺相保護(hù)，電機(jī)被卡死堵轉(zhuǎn)或電機(jī)線斷開一路則停機(jī)報(bào)警，紅燈快速連續(xù)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(guò)流保護(hù)，當(dāng)工作電流大于設(shè)定電流則停機(jī)報(bào)警，紅燈每間隔1秒閃1下；調(diào)速信號(hào)歸零后恢復(fù)。

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(guò)熱保護(hù)，當(dāng)電路板溫度大于設(shè)定溫度則停機(jī)報(bào)警，紅燈每間隔1秒閃2下；調(diào)速信號(hào)歸零后恢復(fù)。

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(guò)壓欠壓保護(hù)，當(dāng)供電電壓超出范圍則停機(jī)報(bào)警，紅燈每間隔1秒閃3下；調(diào)速信號(hào)歸零后恢復(fù)。

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.
