Lower voltage High temperature resistant hall-less induction driver pecification

一、功能特點(diǎn)Feature：

● 無感控制Sensorless control 

● 過壓欠壓保護(hù)、過流保護(hù)、過熱保護(hù) Protection beyond the scope of power supply voltage\

overload protection\over-temperature protection.

● 報警Various alarm instructions 
● 外部電位器調(diào)速speed regulation by External potentiometer

● 外部模擬信號調(diào)速speed regulation by External analog signal  
● PWM控制調(diào)速speed regulation by PWM signal 
● 報警后自動復(fù)位、重啟Automatic reset and restart after alarm 

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

二、端口描述Port definitions：

三、調(diào)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(hù)及報警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、過流保護(hù)，當(dāng)工作電流大于設(shè)定電流則停機(jī)報警，紅燈每間隔1秒閃1下；調(diào)速信號歸零后恢復(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、過熱保護(hù)，當(dāng)電路板溫度大于設(shè)定溫度則停機(jī)報警，紅燈每間隔1秒閃2下；調(diào)速信號歸零后恢復(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、過壓欠壓保護(hù)，當(dāng)供電電壓超出范圍則停機(jī)報警，紅燈每間隔1秒閃3下；調(diào)速信號歸零后恢復(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.
