西門子機床系統黑屏及啟動開關壞維修，故障維修處理：數控機床電氣故障中弱電故障部分主要有 ＣＮＣ 裝置、ＰＭＣ 控制器、ＣＲＴ 顯示器以及伺服單元、輸入／輸出裝置等電子電路。若出現機床系統黑屏及啟動開關失靈故障，可按以下方法排除故障：
    若數控機床按下啟動按鈕后，系統不啟動，首先應該檢查數控機床總開關是否打開；其次，觀察電氣柜中電源盒的指示燈是否亮了，以此來判斷電源盒是否有２２０Ｖ 電源電壓的輸入。
   若(ruo)(ruo)指示燈(deng)不(bu)亮(liang)，檢(jian)(jian)查(cha)(cha)電(dian)(dian)(dian)源(yuan)盒(he)是否(fou)(fou)有(you)(you)(you)２２０Ｖ 電(dian)(dian)(dian)源(yuan)，若(ruo)(ruo)有(you)(you)(you)２２０Ｖ 電(dian)(dian)(dian)源(yuan)，指示燈(deng)不(bu)亮(liang)或(huo)沒有(you)(you)(you)２４Ｖ 電(dian)(dian)(dian)源(yuan)輸出，則為電(dian)(dian)(dian)源(yuan)盒(he)損壞(huai)(huai)。若(ruo)(ruo)有(you)(you)(you)２４Ｖ 電(dian)(dian)(dian)源(yuan)，檢(jian)(jian)查(cha)(cha)系(xi)統(tong)后面是否(fou)(fou)有(you)(you)(you)２４Ｖ 電(dian)(dian)(dian)源(yuan)，若(ruo)(ruo)沒有(you)(you)(you)，則需(xu)檢(jian)(jian)查(cha)(cha)電(dian)(dian)(dian)纜線(xian)是否(fou)(fou)斷(duan)路(lu)。需(xu)注意，２４Ｖ 電(dian)(dian)(dian)源(yuan)短(duan)路(lu)，是電(dian)(dian)(dian)壓(ya)達不(bu)到 ２４Ｖ，也有(you)(you)(you)可能使系(xi)統(tong)不(bu)啟(qi)動(dong)，這就需(xu)檢(jian)(jian)查(cha)(cha)其他(ta)２４Ｖ 電(dian)(dian)(dian)源(yuan)是否(fou)(fou)短(duan)路(lu)；還有(you)(you)(you)電(dian)(dian)(dian)路(lu)中，若(ruo)(ruo)有(you)(you)(you)一路(lu)斷(duan)路(lu)或(huo)開關損壞(huai)(huai)，也可導致系(xi)統(tong)不(bu)啟(qi)動(dong)，若(ruo)(ruo)系(xi)統(tong)后面有(you)(you)(you)２４Ｖ 電(dian)(dian)(dian)源(yuan)，電(dian)(dian)(dian)路(lu)圖檢(jian)(jian)查(cha)(cha)也沒故(gu)障，則有(you)(you)(you)可能是系(xi)統(tong)壞(huai)(huai)了，需(xu)更(geng)換數控(kong)系(xi)統(tong)。
