接口信号描述
|
名称
|
功能
|
|
PUL+（+5V）
|
脉冲控制信号：脉冲上升沿有效；PUL-高电平时4-5V，低电平时0-0.5V。为了可靠响应脉冲信号，脉冲宽度应大于1.6μs。如采用+12V或+24V时需串电阻。
|
|
PUL-（PUL）
|
|
|
DIR+（+5V）
|
方向信号：高/低电平信号，为保证电机可靠换向，方向信号应先于脉冲信号至少 5μs建立。电机的初始运行方向与电机的接线有关，互换任一相绕组（如A+、A-交换）可以改变电机初始运行的方向，DIR-高电平时4～5V，低电平时0～0.5V。
|
|
DIR-（DIR）
|
|
|
ENA+（+5V）
|
使能信号：此输入信号用于使能或禁止。ENA+ 接+5V，ENA-接低电平（或内部光耦导通）时，驱动器将切断电机各相电流使电机处于自由状态，此时步进脉冲不被响应。当不需此功能时，使能信号端悬空即可。
|
|
ENA-（ENA）
|
|
|
FAULT+
|
故障信号OC输出：低电平故障，高电平正常，建议用1K上拉电阻接外部+5V。注意：FAULT+/FAULT-端与电源GND不共地。
