成功修復西門子變頻器6SE70不報警電機不轉解決

當變頻器(qi)（VFD）發生故障時，需要快速恢復工作(zuo)狀態。請記住以(yi)下(xia)有關VFD故障排除的(de)(de)基本(ben)檢(jian)(jian)(jian)查(cha)點(dian)。檢(jian)(jian)(jian)查(cha)控制器(qi)顯示(shi)。大多數VFD控制器(qi)都包含(han)一(yi)個用(yong)于設置驅動器(qi)操作(zuo)的(de)(de)界面(mian)，并顯示(shi)有關其操作(zuo)的(de)(de)信息。雖然信息不盡(jin)相同，但大多數控制器(qi)會告(gao)訴(su)我(wo)們(men)(men)輸入和(he)輸出(chu)端的(de)(de)高(gao)電(dian)(dian)(dian)流，高(gao)電(dian)(dian)(dian)壓和(he)低電(dian)(dian)(dian)壓，高(gao)溫，內部(bu)故障，甚至是一(yi)些高(gao)級電(dian)(dian)(dian)源診斷(duan)。檢(jian)(jian)(jian)查(cha)連(lian)接(jie)(jie)。如(ru)果(guo)故障代碼無法幫助我(wo)們(men)(men)找出(chu)問(wen)題，請檢(jian)(jian)(jian)查(cha)連(lian)接(jie)(jie)。連(lian)接(jie)(jie)松(song)動是VFD應用(yong)中最常見的(de)(de)錯誤操作(zuo)原因。如(ru)果(guo)我(wo)們(men)(men)仍然通電(dian)(dian)(dian)，我(wo)們(men)(men)還(huan)可以(yi)檢(jian)(jian)(jian)查(cha)連(lian)接(jie)(jie)上的(de)(de)電(dian)(dian)(dian)壓降; 或者如(ru)果(guo)斷(duan)電(dian)(dian)(dian)，則(ze)通過(guo)連(lian)接(jie)(jie)來抵抗。
