西門子機床611電源上電跳閘指示燈不亮故障分析解決；

1，電源通(tong)電無反應(ying)，各(ge)指示(shi)燈均不(bu)亮(liang)

電(dian)(dian)(dian)(dian)源在機床(chuang)中開機沒(mei)有(you)任(ren)何指示時，我們應(ying)當首先檢(jian)測輸入(ru)電(dian)(dian)(dian)(dian)壓(ya)(ya)是(shi)否(fou)(fou)(fou)正(zheng)(zheng)常，是(shi)否(fou)(fou)(fou)達(da)到(dao)電(dian)(dian)(dian)(dian)源規定(ding)的輸入(ru)電(dian)(dian)(dian)(dian)壓(ya)(ya)，如果沒(mei)有(you)輸入(ru)電(dian)(dian)(dian)(dian)壓(ya)(ya)，則應(ying)當檢(jian)查進(jin)線開關是(shi)否(fou)(fou)(fou)損壞(huai)，接(jie)線是(shi)否(fou)(fou)(fou)接(jie)牢，如果輸入(ru)電(dian)(dian)(dian)(dian)壓(ya)(ya)正(zheng)(zheng)常，剛首先應(ying)當將機床(chuang)下電(dian)(dian)(dian)(dian)，將電(dian)(dian)(dian)(dian)源拆下，打開電(dian)(dian)(dian)(dian)源，看電(dian)(dian)(dian)(dian)源內部保險是(shi)否(fou)(fou)(fou)完好(hao)，如果有(you)損壞(huai)，應(ying)當先排除引起保險損壞(huai)的原因(yin)，然后換上新的符合規定(ding)的保險；如果保險完好(hao)，則應(ying)檢(jian)查電(dian)(dian)(dian)(dian)源內部整流電(dian)(dian)(dian)(dian)路是(shi)否(fou)(fou)(fou)正(zheng)(zheng)常，550V電(dian)(dian)(dian)(dian)壓(ya)(ya)是(shi)否(fou)(fou)(fou)正(zheng)(zheng)常，以及PFC電(dian)(dian)(dian)(dian)路是(shi)否(fou)(fou)(fou)正(zheng)(zheng)常。

2，電源(yuan)指示三(san)相LED亮(liang)（紅）

如(ru)果(guo)(guo)電(dian)源(yuan)通電(dian)后輸入電(dian)壓檢測(ce)LED常亮，則(ze)首先檢測(ce)輸入電(dian)壓是(shi)否有(you)缺相，如(ru)果(guo)(guo)輸入電(dian)壓測(ce)試(shi)正常，則(ze)應(ying)著重檢測(ce)電(dian)源(yuan)內部的輸入電(dian)源(yuan)檢測(ce)電(dian)路(lu)是(shi)否有(you)損壞(huai)，如(ru)果(guo)(guo)有(you)損壞(huai)也(ye)會報故障。

3，面板(ban)上的5V指示(shi)燈亮（紅(hong)）

如果面板上5V指(zhi)示燈常亮，則(ze)說(shuo)明電(dian)(dian)源內(nei)部的5V電(dian)(dian)源過(guo)低或過(guo)高，則(ze)應當檢查5V電(dian)(dian)源電(dian)(dian)路。

4，面板上(shang)SPP燈常亮（紅）

面(mian)板上SPP燈常(chang)亮，則說明電源的總線（－X351）輸出電源不(bu)正常(chang)，經(jing)測(ce)試，各組電源均偏低，通過檢測(ce)，故障(zhang)原(yuan)因為基準、反(fan)饋電路(lu)的故障(zhang)。

5，電源不能(neng)有效(xiao)加使能(neng)

這類故(gu)障原因(yin)一般為電(dian)(dian)源(yuan)板(ban)的使能電(dian)(dian)路(lu)(lu)(lu)故(gu)障，如(ru)果(guo)使能電(dian)(dian)路(lu)(lu)(lu)完好，則也應(ying)當檢(jian)測(ce)(ce)功(gong)率板(ban)電(dian)(dian)路(lu)(lu)(lu)，最后(hou)還(huan)應(ying)當檢(jian)測(ce)(ce)電(dian)(dian)源(yuan)板(ban)的充電(dian)(dian)電(dian)(dian)路(lu)(lu)(lu)是(shi)否正常。
