西門子控制器6RA70只要啟動就燒保險，經常會(hui)(hui)碰到變(bian)(bian)頻器(qi)(qi)無輸(shu)出(chu)現象。驅(qu)動(dong)電(dian)(dian)(dian)路損(sun)壞、逆變(bian)(bian)模塊(kuai)損(sun)壞都有可能(neng)引起(qi)變(bian)(bian)頻器(qi)(qi)無輸(shu)出(chu)。我們把這(zhe)些統稱(cheng)為(wei)硬(ying)故(gu)(gu)(gu)(gu)障(zhang)(zhang)。例如(ru)重慶變(bian)(bian)頻器(qi)(qi)中二極(ji)管(guan)、三極(ji)管(guan)、場效應晶體管(guan)，電(dian)(dian)(dian)阻、電(dian)(dian)(dian)容等(deng)元(yuan)件(jian)(jian)出(chu)現擊穿或燒斷、PCB上印(yin)(yin)制(zhi)線燒斷、被(bei)利(li)器(qi)(qi)劃斷、元(yuan)件(jian)(jian)的(de)(de)(de)引腳(jiao)(jiao)因銹蝕而斷腳(jiao)(jiao)等(deng)有明(ming)顯(xian)損(sun)壞的(de)(de)(de)跡象，或者(zhe)用萬用表就能(neng)檢(jian)(jian)(jian)查出(chu)來的(de)(de)(de)，這(zhe)些故(gu)(gu)(gu)(gu)障(zhang)(zhang)都比(bi)較容易判斷和檢(jian)(jian)(jian)查的(de)(de)(de)，通(tong)常稱(cheng)為(wei)硬(ying)故(gu)(gu)(gu)(gu)障(zhang)(zhang)，提示大家硬(ying)故(gu)(gu)(gu)(gu)障(zhang)(zhang)是比(bi)較容易檢(jian)(jian)(jian)查出(chu)來的(de)(de)(de)一(yi)(yi)(yi)類故(gu)(gu)(gu)(gu)障(zhang)(zhang)。經過(guo)仔(zi)細檢(jian)(jian)(jian)查pcb印(yin)(yin)制(zhi)線、仔(zi)細用萬用表檢(jian)(jian)(jian)查元(yuan)件(jian)(jian)的(de)(de)(de)好壞都未能(neng)找(zhao)出(chu)損(sun)壞的(de)(de)(de)元(yuan)件(jian)(jian)，但(dan)變(bian)(bian)頻器(qi)(qi)就是不能(neng)工作(zuo)這(zhe)樣一(yi)(yi)(yi)類故(gu)(gu)(gu)(gu)障(zhang)(zhang)稱(cheng)為(wei)軟故(gu)(gu)(gu)(gu)障(zhang)(zhang)，這(zhe)一(yi)(yi)(yi)類故(gu)(gu)(gu)(gu)障(zhang)(zhang)通(tong)常是由于電(dian)(dian)(dian)容、集成電(dian)(dian)(dian)路等(deng)元(yuan)件(jian)(jian)變(bian)(bian)質，在不加電(dian)(dian)(dian)狀(zhuang)(zhuang)態(tai)時檢(jian)(jian)(jian)測這(zhe)些元(yuan)件(jian)(jian)時它是好的(de)(de)(de)，加電(dian)(dian)(dian)后檢(jian)(jian)(jian)測這(zhe)些元(yuan)件(jian)(jian)它的(de)(de)(de)性能(neng)會(hui)(hui)變(bian)(bian)差(cha)，或者(zhe)是電(dian)(dian)(dian)路板中PCB印(yin)(yin)制(zhi)線出(chu)現暗斷的(de)(de)(de)情況。單元(yuan)故(gu)(gu)(gu)(gu)障(zhang)(zhang)包(bao)括：熔(rong)斷器(qi)(qi)故(gu)(gu)(gu)(gu)障(zhang)(zhang)、單元(yuan)過(guo)熱、驅(qu)動(dong)故(gu)(gu)(gu)(gu)障(zhang)(zhang)、光(guang)纖故(gu)(gu)(gu)(gu)障(zhang)(zhang)、單元(yuan)過(guo)壓(ya)。外部故(gu)(gu)(gu)(gu)障(zhang)(zhang)必須先(xian)解除(chu)高壓(ya)分斷（柜門(men)按(an)鈕或外部接(jie)點(dian)）狀(zhuang)(zhuang)態(tai)再系(xi)統復位，才能(neng)使系(xi)統恢(hui)復到正(zheng)(zheng)常狀(zhuang)(zhuang)態(tai)；除(chu)外部故(gu)(gu)(gu)(gu)障(zhang)(zhang)以外的(de)(de)(de)重故(gu)(gu)(gu)(gu)障(zhang)(zhang)發生后，直接(jie)系(xi)統復位即可使系(xi)統恢(hui)復到正(zheng)(zheng)常狀(zhuang)(zhuang)態(tai)，但(dan)在再次(ci)上電(dian)(dian)(dian)前一(yi)(yi)(yi)定要找(zhao)出(chu)故(gu)(gu)(gu)(gu)障(zhang)(zhang)原因。
