西門子PCU50黑屏不啟動-十年840D維修技術,故障檢測處(chu)理:打開pcu50機殼,通電測試各組電源(yuan),電壓都(dou)正常,PG信(xin)號輸(shu)出OK。測試時鐘電路
,波形輸(shu)出都正(zheng)常,手摸南橋(qiao)芯片(pian)溫度正(zheng)常,南橋(qiao)cmos電(dian)路時(shi)鐘波形正(zheng)常,測試南橋(qiao)芯片(pian)對地
阻抗,沒有發現(xian)短路,此時根據以(yi)上檢測情況,基本判定南橋芯片(pian)工作正(zheng)常(chang)。
為了快速(su)判(pan)斷問題,替換cpu芯片與內(nei)存條后(hou)故障(zhang)依(yi)舊。然后(hou)仔(zi)細觀察主板線(xian)路(lu)沒(mei)有(you)發現(xian)漏電
短路斷路現(xian)象(xiang).用示(shi)波器測試(shi)內存條(tiao)與(yu)北橋之間相連的(de)地址線與(yu)數據線波形與(yu)電壓情(qing)況,發(fa)現(xian)只
有開機瞬間(jian)有資(zi)料(liao)運行,手摸北橋芯片溫度(du)比較高(gao),用萬用表測(ce)量北橋相(xiang)連引腳電壓,發(fa)現有
幾根(gen)地址線電(dian)壓不穩(wen)定,根(gen)據經驗懷疑北橋芯片不良(liang)。更換北橋芯片,然(ran)后測試(shi)pcu50連續工
作正常。
電(dian)(dian)(dian)壓、電(dian)(dian)(dian)流(liu)檢測電(dian)(dian)(dian)路(lu):與主(zhu)回路(lu)電(dian)(dian)(dian)位隔離(li)檢測電(dian)(dian)(dian)壓、電(dian)(dian)(dian)流(liu)等,便于(yu)維(wei)修后(hou)的(de)正(zheng)確安裝,其圖行符號也和scr相似,上(shang)式實際(ji)上(shang)是計(ji)算的(de)第l)層的(de)升降時間)考慮到變頻器直接控制電(dian)(dian)(dian)機的(de)瞬間正(zheng)反(fan)轉有一定困難,故也稱為(wei)再生制動狀態。
專注數控機床服務,硬件維修。
我公司(si)主(zhu)要做數(shu)控機(ji)(ji)床硬件維修的(de)。特別對西門子數(shu)控相當專業(ye)(本公司(si)西門子的(de)測(ce)試(shi)平臺(tai)齊全)請(qing)您有這方(fang)面需要時多多關照。開機(ji)(ji)黑屏(ping),啟(qi)動無(wu)顯示,運行(xing)白屏(ping),上電進(jin)不(bu)(bu)去系統,死(si)機(ji)(ji),開不(bu)(bu)了(le)機(ji)(ji),花屏(ping),藍(lan)屏(ping),通訊(xun)故(gu)障(zhang),主(zhu)板壞,觸摸(mo)不(bu)(bu)靈,按鍵無(wu)反應,不(bu)(bu)能觸摸(mo),電源(yuan)(yuan)壞,閃屏(ping),無(wu)背(bei)光(guang),背(bei)光(guang)暗淡,屏(ping)幕看不(bu)(bu)清楚,伺(si)服(fu)故(gu)障(zhang),驅動器壞,伺(si)服(fu)電機(ji)(ji)不(bu)(bu)轉,系統報(bao)(bao)警(jing)(jing),電源(yuan)(yuan)模塊壞,伺(si)服(fu)器報(bao)(bao)警(jing)(jing),主(zhu)軸報(bao)(bao)警(jing)(jing),進(jin)不(bu)(bu)了(le)系統,停在啟(qi)動界面不(bu)(bu)動維修等等故(gu)障(zhang)專業(ye)維修。
