龍門加工中心840D伺服控制器壞故障(zhang)檢(jian)測(ce)診斷：在檢(jian)修中應首先檢(jian)查電源電路是否(fou)正常,然后再檢(jian)查其他(ta)部(bu)分。電源故障(zhang)有以下幾(ji)種情況(kuang):

(1)無電(dian)源電(dian)壓或電(dian)源電(dian)壓低(di)。數控系統常采用±5V、±12V、±15V、±24V ,少(shao)數采用+ 3. 3V。而(er)電(dian)源電(dian)壓的(de)不(bu)正常,即會引(yin)起系統工作異常。

(2)用電壓表檢測(ce)電源(yuan)電壓正常,但(dan)用示(shi)波器(qi)檢測(ce)發(fa)現電壓波形(xing)紋(wen)波大。通常是電源(yuan)濾波電容(rong)開(kai)路(lu)，整流二極管不良或虛焊(han)造(zao)(zao)成的，有時(shi)是某元件擊(ji)穿損(sun)壞(huai)造(zao)(zao)成電源(yuan)負載過重。

(3)系(xi)(xi)統(tong)(tong)(tong)剛(gang)開機(ji)時(shi)(shi)正(zheng)常(chang)(chang)(chang),工作一段時(shi)(shi)間后(hou)(hou)電(dian)(dian)(dian)源(yuan)(yuan)(yuan)電(dian)(dian)(dian)壓下降(jiang)(jiang)。這(zhe)通(tong)常(chang)(chang)(chang)是(shi)(shi)(shi)穩壓電(dian)(dian)(dian)路(lu)或(huo)(huo)大功率三極管不良。在溫度升(sheng)高后(hou)(hou)引(yin)起(qi)電(dian)(dian)(dian)源(yuan)(yuan)(yuan)電(dian)(dian)(dian)壓下降(jiang)(jiang),也可能(neng)(neng)是(shi)(shi)(shi)某一元件虛(xu)焊，溫度升(sheng)高后(hou)(hou)出現(xian)接觸不良。無(wu)電(dian)(dian)(dian)源(yuan)(yuan)(yuan)電(dian)(dian)(dian)壓或(huo)(huo)電(dian)(dian)(dian)源(yuan)(yuan)(yuan)電(dian)(dian)(dian)壓嚴重(zhong)降(jiang)(jiang)低(di)時(shi)(shi),會(hui)引(yin)起(qi)系(xi)(xi)統(tong)(tong)(tong)中(zhong)斷(duan)或(huo)(huo)停止工作,這(zhe)種故(gu)障易檢(jian)測和(he)發(fa)現(xian)。當電(dian)(dian)(dian)源(yuan)(yuan)(yuan)帶負(fu)載(zai)能(neng)(neng)力下降(jiang)(jiang)或(huo)(huo)濾波電(dian)(dian)(dian)路(lu)失效時(shi)(shi),卻是(shi)(shi)(shi)難以判斷(duan)的。它(ta)會(hui)使系(xi)(xi)統(tong)(tong)(tong)突然停止工作,引(yin)起(qi)設(she)(she)備(bei)(bei)的突發(fa)事故(gu),造(zao)成設(she)(she)備(bei)(bei)及人(ren)員傷害(hai),務(wu)必引(yin)起(qi)高度重(zhong)視。如一臺由FANUC 3MA組成的加工中(zhong)心,開機(ji)后(hou)(hou)CRT無(wu)任何顯示。用萬(wan)用表檢(jian)測系(xi)(xi)統(tong)(tong)(tong)電(dian)(dian)(dian)源(yuan)(yuan)(yuan)板A14B - 0067 - B002 - 01 ,發(fa)現(xian)+ 5V電(dian)(dian)(dian)源(yuan)(yuan)(yuan)電(dian)(dian)(dian)壓為3. 75V ,去掉負(fu)載(zai)檢(jian)測, +5V電(dian)(dian)(dian)源(yuan)(yuan)(yuan)為+ 4. 95V。說明(ming)電(dian)(dian)(dian)源(yuan)(yuan)(yuan)帶負(fu)載(zai)能(neng)(neng)力低(di)或(huo)(huo)負(fu)載(zai)有(you)短路(lu)存在 。經(jing)檢(jian)查(cha)負(fu)載(zai)正(zheng)常(chang)(chang)(chang)。說明(ming)電(dian)(dian)(dian)源(yuan)(yuan)(yuan)帶負(fu)載(zai)能(neng)(neng)力下降(jiang)(jiang)。經(jing)檢(jian)查(cha)更換C36濾波電(dian)(dian)(dian)容(rong),系(xi)(xi)統(tong)(tong)(tong)正(zheng)常(chang)(chang)(chang)工作。
