求助求助       現在是用PLC控制步進(jìn)電機正反轉往復運動(dòng)，57的步進(jìn)電機，驅動(dòng)器輸入電壓范圍9-42V，脈沖信號3.3-24V通用（所以沒(méi)有串電阻），直接都用24V電壓，現在問(wèn)題是用一段時(shí)間后DIR方向信號不管有沒(méi)有24V信號 電機都只會(huì )一個(gè)方向運轉，換過(guò)兩個(gè)驅動(dòng)器了都是用不了多長(cháng)時(shí)間就會(huì )只能朝一個(gè)方向運轉，方向信號失靈，打電話(huà)問(wèn)廠(chǎng)家說(shuō)有干擾或驅動(dòng)器壞了，已經(jīng)連續換過(guò)三個(gè)驅動(dòng)器了，求大神指點(diǎn)�。�！哪里出問(wèn)題了？？？——————————
