 | 3 | 脉冲信号   发生器 | VOH ) | 输出 | 1.5V≤V≤, at5V | Yellow wire,this is the open collector output(NPN),which can detect the rotation speed using the FG output according to the phase shift |
|---|---|---|---|---|---|
 | VOL ) | 3mA max |
 | （Signal current) | 3 pulse,can be customized) |
 | Output pulse | 0- 5.0V |
 | 4 | 正反转 | Input voltage) | 输入 | 0-5.0V | White wire, CCW/CW Select |
 | VOH ) | Min 1.5V | CCW ,High=CCW |
 | VOL ) | Max 0.6V | CW ,Low=CW |
 | 5 | 脉宽调制 | VOH ) | 输入 | Mini 1.5V | Blue wire |
 | VOL ) | Max 0.6V | Motor stop,High=stop |
 | Input voltage) |  | Motor running,low=start |
 | 脉冲频率 | 建议脉冲使用范围20kHz ~ 30kHz |  |
 | 备注:   1、Vcc 与GND 端口不可交换使用。   2、请在马达停止状态下进行CW / CCW 切换 ，在运转过程中切换有可能造成内部电子元件损坏。   3、电机启动方法 ．红色引线接正极电源 ，黑色引线为GND 及白色引线端口为低电平时 ，电机启动 ，电机初始转向通常为CCW 。当需要切换转向时 ，将橙色引线、白色引线同时为低电平时，即切换电机转向。 |
