龍門加工中心840D伺服控制器壞故障檢(jian)測(ce)診(zhen)斷：在檢(jian)修中應首先(xian)檢(jian)查電源電路是否正常,然后再檢(jian)查其(qi)他(ta)部分。電源故障有以下幾種情況:

(1)無電(dian)(dian)源電(dian)(dian)壓或電(dian)(dian)源電(dian)(dian)壓低。數(shu)控系(xi)統常采(cai)用±5V、±12V、±15V、±24V ,少數(shu)采(cai)用+ 3. 3V。而電(dian)(dian)源電(dian)(dian)壓的不正常,即會引起系(xi)統工作異常。

(2)用(yong)電(dian)(dian)壓表檢測電(dian)(dian)源(yuan)(yuan)電(dian)(dian)壓正常,但用(yong)示(shi)波(bo)(bo)器檢測發現電(dian)(dian)壓波(bo)(bo)形紋(wen)波(bo)(bo)大。通常是電(dian)(dian)源(yuan)(yuan)濾波(bo)(bo)電(dian)(dian)容開路，整流二極管(guan)不(bu)良或虛焊造(zao)成的(de)，有時(shi)是某元(yuan)件(jian)擊穿損壞造(zao)成電(dian)(dian)源(yuan)(yuan)負載過重(zhong)。

(3)系統剛開(kai)機(ji)時(shi)(shi)正常,工作(zuo)一段時(shi)(shi)間后(hou)(hou)電(dian)(dian)(dian)源(yuan)電(dian)(dian)(dian)壓(ya)下(xia)降。這通(tong)常是穩壓(ya)電(dian)(dian)(dian)路或大(da)功率三極(ji)管不(bu)良。在溫(wen)度升(sheng)高后(hou)(hou)引(yin)起電(dian)(dian)(dian)源(yuan)電(dian)(dian)(dian)壓(ya)下(xia)降,也可能是某一元件(jian)虛焊，溫(wen)度升(sheng)高后(hou)(hou)出現接觸不(bu)良。無電(dian)(dian)(dian)源(yuan)電(dian)(dian)(dian)壓(ya)或電(dian)(dian)(dian)源(yuan)電(dian)(dian)(dian)壓(ya)嚴重降低(di)時(shi)(shi),會(hui)引(yin)起系統中斷或停止工作(zuo),這種故障(zhang)易檢(jian)(jian)(jian)測和發(fa)(fa)現。當電(dian)(dian)(dian)源(yuan)帶負載(zai)能力下(xia)降或濾(lv)波電(dian)(dian)(dian)路失(shi)效時(shi)(shi),卻(que)是難以(yi)判斷的(de)(de)。它會(hui)使系統突然停止工作(zuo),引(yin)起設(she)備的(de)(de)突發(fa)(fa)事故,造成設(she)備及人(ren)員傷(shang)害,務必引(yin)起高度重視。如一臺由FANUC 3MA組成的(de)(de)加工中心,開(kai)機(ji)后(hou)(hou)CRT無任何顯示。用萬用表檢(jian)(jian)(jian)測系統電(dian)(dian)(dian)源(yuan)板A14B - 0067 - B002 - 01 ,發(fa)(fa)現+ 5V電(dian)(dian)(dian)源(yuan)電(dian)(dian)(dian)壓(ya)為3. 75V ,去掉負載(zai)檢(jian)(jian)(jian)測, +5V電(dian)(dian)(dian)源(yuan)為+ 4. 95V。說明(ming)(ming)電(dian)(dian)(dian)源(yuan)帶負載(zai)能力低(di)或負載(zai)有短路存在 。經檢(jian)(jian)(jian)查負載(zai)正常。說明(ming)(ming)電(dian)(dian)(dian)源(yuan)帶負載(zai)能力下(xia)降。經檢(jian)(jian)(jian)查更(geng)換(huan)C36濾(lv)波電(dian)(dian)(dian)容,系統正常工作(zuo)。
