1.電(dian)源模塊故障指示
電源模(mo)塊上有6個LED狀態指示燈。
數控機床(chuang)廠含義如下:
1)數控機床廠(chang)“SPP"亮:DC15V控制電(dian)源(yuan)故(gu)障(zhang)。
2)“5v故障"亮:DC5V控(kong)制電源(yuan)故障。
3)“EXT"亮、“模塊使能(neng)"亮:電源模塊未(wei)“使能(neng)"。
4)“EXT"不(bu)亮、“模塊(kuai)使能"亮:電(dian)(dian)源模塊(kuai)巳(si)“使能",數控機床廠直流母線已充電(dian)(dian),驅(qu)動(dong)器可以工作。
5)“三"亮:進線電源故障。
6)U。c.,。。亮:直(zhi)流(liu)母線電壓過高。

西門子電源模塊維修案例:
1.一(yi)臺進口數(shu)(shu)控車(che)床(西(xi)門子810D系統),開(kai)機(ji)后(hou)(hou)屏幕上出(chu)現報警“NC、PLC無法連接",打開(kai)電(dian)(dian)(dian)氣(qi)柜后(hou)(hou)發現,電(dian)(dian)(dian)源(yuan)模(mo)塊和(he)(he)NCU模(mo)塊上的指示燈和(he)(he)數(shu)(shu)碼(ma)管(guan)均沒有顯示,而(er)電(dian)(dian)(dian)源(yuan)模(mo)塊進線端電(dian)(dian)(dian)壓用三用表測(ce)量為395V,因此判(pan)定該(gai)故(gu)障是由于進線電(dian)(dian)(dian)壓偏高而(er)導致(zhi)電(dian)(dian)(dian)源(yuan)模(mo)塊內(nei)部(bu)電(dian)(dian)(dian)源(yuan)電(dian)(dian)(dian)路(lu)出(chu)現問(wen)題,打開(kai)模(mo)塊,檢測(ce)內(nei)部(bu)電(dian)(dian)(dian)源(yuan)部(bu)分,發現一(yi)只大功率場效應管(guan)燒壞(huai),更換損壞(huai)元器件,并調整該(gai)廠房電(dian)(dian)(dian)網(wang)電(dian)(dian)(dian)壓至380V后(hou)(hou)重新開(kai)機(ji),系統啟動正常。
