西門子PCU50黑屏不啟動-十年840D維修技術,故障檢測(ce)(ce)處(chu)理:打開(kai)pcu50機殼,通(tong)電(dian)(dian)測(ce)(ce)試各組電(dian)(dian)源,電(dian)(dian)壓都正常,PG信號輸出OK。測(ce)(ce)試時鐘電(dian)(dian)路
,波形輸出都(dou)正(zheng)常,手摸南(nan)橋(qiao)芯(xin)片溫度(du)正(zheng)常,南(nan)橋(qiao)cmos電路(lu)時鐘波形正(zheng)常,測(ce)試(shi)南(nan)橋(qiao)芯(xin)片對地
阻抗,沒有發現短路,此(ci)時(shi)根據以(yi)上檢測(ce)情況,基本判定南橋(qiao)芯片工(gong)作正常。
為了快速判(pan)斷問題,替換cpu芯片與內存條后(hou)故障(zhang)依舊。然后(hou)仔細觀察主板線路沒有發現漏電
短路斷路現象.用示波器測試內存(cun)條(tiao)與(yu)北橋之間(jian)相(xiang)連(lian)的地址線與(yu)數(shu)據線波形與(yu)電壓(ya)情(qing)況,發現只
有(you)開機瞬間有(you)資(zi)料運行,手摸北橋芯片溫度比較(jiao)高,用萬用表測量北橋相連(lian)引腳電(dian)壓,發現有(you)
幾根地址線電壓(ya)不穩定,根據經驗懷疑北橋(qiao)芯片不良。更(geng)換北橋(qiao)芯片,然后測試(shi)pcu50連(lian)續工
作正常。
電(dian)(dian)(dian)壓、電(dian)(dian)(dian)流(liu)檢測(ce)電(dian)(dian)(dian)路:與主回路電(dian)(dian)(dian)位隔離檢測(ce)電(dian)(dian)(dian)壓、電(dian)(dian)(dian)流(liu)等,便于維修后(hou)的(de)正確(que)安(an)裝,其圖行符號(hao)也和(he)scr相似,上式(shi)實際上是計(ji)算的(de)第l)層(ceng)的(de)升(sheng)降(jiang)時間(jian))考慮到變頻器直接(jie)控制(zhi)電(dian)(dian)(dian)機的(de)瞬間(jian)正反轉有一定(ding)困(kun)難,故也稱為(wei)再生制(zhi)動狀(zhuang)態。
專注數控機床服務,硬件維修。
