西門子611電源模塊燈不亮-專業維修測試平臺，電(dian)(dian)(dian)(dian)源(yuan)(yuan)(yuan)是電(dian)(dian)(dian)(dian)路板的(de)(de)能源(yuan)(yuan)(yuan)供(gong)(gong)應部(bu)分(fen)(fen)，電(dian)(dian)(dian)(dian)源(yuan)(yuan)(yuan)不正(zheng)常(chang)，電(dian)(dian)(dian)(dian)路板的(de)(de)工(gong)作(zuo)必然異常(chang)。而且，電(dian)(dian)(dian)(dian)源(yuan)(yuan)(yuan)部(bu)分(fen)(fen)故(gu)障(zhang)率較高，修理時應足(zu)夠(gou)重(zhong)視(shi)，在(zai)外觀法檢(jian)查(cha)(cha)后，可先對(dui)(dui)電(dian)(dian)(dian)(dian)源(yuan)(yuan)(yuan)部(bu)分(fen)(fen)進行(xing)檢(jian)查(cha)(cha)。? 電(dian)(dian)(dian)(dian)路板的(de)(de)工(gong)作(zuo)電(dian)(dian)(dian)(dian)源(yuan)(yuan)(yuan)，有(you)的(de)(de)是由外部(bu)電(dian)(dian)(dian)(dian)源(yuan)(yuan)(yuan)系統(tong)供(gong)(gong)給；有(you)的(de)(de)由板上本身的(de)(de)穩(wen)(wen)(wen)(wen)壓電(dian)(dian)(dian)(dian)路產生(sheng)，電(dian)(dian)(dian)(dian)源(yuan)(yuan)(yuan)檢(jian)查(cha)(cha)包括輸(shu)出電(dian)(dian)(dian)(dian)壓穩(wen)(wen)(wen)(wen)定性(xing)檢(jian)查(cha)(cha)和輸(shu)出紋波檢(jian)查(cha)(cha)。輸(shu)出紋波過大，會引起系統(tong)不穩(wen)(wen)(wen)(wen)定，用示波器交流輸(shu)入檔可檢(jian)查(cha)(cha)紋波幅值，紋波大一(yi)般是由集成穩(wen)(wen)(wen)(wen)壓器損壞(huai)或濾(lv)波電(dian)(dian)(dian)(dian)容不良引起。運算放大器、比(bi)較器，有(you)些(xie)用單電(dian)(dian)(dian)(dian)源(yuan)(yuan)(yuan)供(gong)(gong)電(dian)(dian)(dian)(dian)，有(you)些(xie)用雙電(dian)(dian)(dian)(dian)源(yuan)(yuan)(yuan)供(gong)(gong)電(dian)(dian)(dian)(dian)，用雙電(dian)(dian)(dian)(dian)源(yuan)(yuan)(yuan)的(de)(de)運放，要求正(zheng)負供(gong)(gong)電(dian)(dian)(dian)(dian)對(dui)(dui)稱，其差值一(yi)般不能大于(yu)0.2V（具有(you)調(diao)零功能的(de)(de)運放除外）。

當611電(dian)源單元狀態指示燈LED亮時，故(gu)障(zhang)原(yuan)因(yin)可(ke)能(neng)(neng)是CP3外部連接開關SB2、SB3、SQ21及(ji)接線(xian)故(gu)障(zhang)，也可(ke)能(neng)(neng)是內部電(dian)路RY2、RY3、RY4繼電(dian)器控制電(dian)路故(gu)障(zhang)。

當611電(dian)源單(dan)(dan)元(yuan)(yuan)指示燈和(he)故障狀態指示燈都亮時，如果(guo)機(ji)床斷電(dian)再送電(dian)故障解除，則為電(dian)源單(dan)(dan)元(yuan)(yuan)受到外界(jie)的(de)干擾導致。如果(guo)不能解除，則可能是(shi)電(dian)源單(dan)(dan)元(yuan)(yuan)輸出電(dian)壓(ya)+5V、+15V、-15、+24V直流電(dian)壓(ya)異常或內部電(dian)路(lu)故障。
