龍門銑西門子840D系統PCU50黑屏維修，西門子加工中心PCU50系統無顯示維修故障檢測：如一臺由 數控系統840D的加工中心 ,工作一段時間后 ,突 然 CRT 黑屏 ,機床無動作 。關掉電源 ,再送上電源 ,機床又能工 作一段時間 。檢查電源一切正常 。故障可能在系統主板上 。經檢修 主 板A16B - 1000 - 0220/ 04A ,發 現 兩 個 晶 振 中  的 一 個16. 3840MHz晶振內部接觸不良 ,更換后使用至今未再發生同類故障 。另外，經過長期運行的數控機床，由于其機械傳動部件磨損，電氣無件性能變化等原因，也需對其有關參數進行調整。有些機床的故障往往就是由于未及時修改某些不適應的參數所致。當然這些故障都是屬于故障的范疇。
復位電路
復位電路也是存在于系統主板上的電路 ,它是大規模數字 集成電路*的電路 。微處理器 、接口電路等都有復位端子 。
復位(wei)電路(lu)產生的復位(wei)脈沖把程序計數器(qi)清(qing)零 ，使 CPU從存儲器(qi)中調出初(chu)始化(hua)文件(jian) ,對各(ge)控制芯片端口進行初(chu)始化(hua) 。如果復位(wei) 電路(lu)不良(liang) ,系統會發生紊亂(luan) 、死機等故障 。
