使用QD75-D4控制雷賽步進(jìn)，目前接線(xiàn)方式是 步進(jìn)驅動(dòng)器PUL+與DIR+ 接24V+, QD75-D4 CW-接步進(jìn)驅動(dòng)器的PUL-, CCW-接步進(jìn)驅動(dòng)器的DIR-。但電機只能一個(gè)方向選擇。

QD75-D4軟件內設定(WORS2軟件)脈沖方式CW/CCW。記得QD75D是差動(dòng)輸出的，為何軟件內可以選擇脈沖+方向呢？即使我選擇了脈沖+方向也是只能一個(gè)方向選擇。試過(guò)將步進(jìn)拆除用伺服可以運行，所以排除了程式及模組的問(wèn)題了。應該還是接線(xiàn)的問(wèn)題，求大師指導

差動(dòng)與單脈沖和雙脈沖有什么關(guān)系
