我昨天也遇見(jiàn)電機反轉現象，具體過(guò)程是：主電機啟動(dòng)后約5s時(shí)間，這時(shí)間在plc里面有個(gè)定時(shí)器5s，機器就不能正常動(dòng)作了，這時(shí)候主電機就開(kāi)始慢慢的反轉，找了很久沒(méi)有發(fā)現問(wèn)題，driver也沒(méi)報警，最后我將driver里面的速度，換了一個(gè)速度后又恢復正常了，真怪�。�！
我們公司該機器在機器停下來(lái)的時(shí)候電機需要停在一定的角度，不知道是不是機器需要停的時(shí)候缺項導致

干擾造成的!
自動(dòng)化單機，生產(chǎn)線(xiàn)，項目編程調試！
