840D西門子系統龍門銑床報300504修復解決;編碼器的硬件故障
1.檢查電纜接頭盒編碼器信號,若編碼器有故障則更換
2.檢查當前有效測量系統1/2選擇信號DB31~DB61.DBX1.5或DBX1.6是否為1西門子數控系統與電源電網,機械系統等相關聯,而且在工作中一直處于頻繁的啟動和運行狀態,因而這也是故障較多的部分。
其主要故(gu)(gu)障有:①系(xi)(xi)(xi)統(tong)(tong)損壞。一(yi)般(ban)(ban)由(you)于(yu)網(wang)(wang)絡電(dian)(dian)壓(ya)波動(dong)太大,或(huo)電(dian)(dian)壓(ya)沖(chong)擊(ji)造(zao)成。我(wo)(wo)國大部分(fen)(fen)地(di)區電(dian)(dian)網(wang)(wang)質量不(bu)好,會給機(ji)床(chuang)(chuang)帶來電(dian)(dian)壓(ya)超限,尤其是(shi)瞬(shun)間超限,如(ru)無(wu)(wu)專門(men)的(de)電(dian)(dian)壓(ya)監控儀,則很難測到,在(zai)查(cha)找故(gu)(gu)障原因(yin)時(shi),要加(jia)以注意,還(huan)有一(yi)些是(shi)由(you)于(yu)特殊原因(yin)造(zao)成的(de)損壞。如(ru)華北某(mou)廠由(you)于(yu)雷擊(ji)中工(gong)廠變電(dian)(dian)站并竄入電(dian)(dian)網(wang)(wang)而(er)造(zao)成多(duo)臺(tai)機(ji)床(chuang)(chuang)伺(si)服系(xi)(xi)(xi)統(tong)(tong)損壞。②無(wu)(wu)控制(zhi)指(zhi)令(ling),而(er)電(dian)(dian)機(ji)高速(su)(su)運(yun)轉(zhuan)。這種(zhong)故(gu)(gu)障的(de)原因(yin)是(shi)速(su)(su)度(du)(du)環(huan)開(kai)環(huan)或(huo)正(zheng)反(fan)饋(kui)。如(ru)在(zai)東北某(mou)廠,引(yin)進(jin)的(de)西德(de)公司轉(zhuan)子銑床(chuang)(chuang)在(zai)調試中,機(ji)床(chuang)(chuang)X軸在(zai)無(wu)(wu)指(zhi)令(ling)的(de)情(qing)況下(xia)(xia),高速(su)(su)運(yun)轉(zhuan),經分(fen)(fen)析我(wo)(wo)們認(ren)為是(shi)正(zheng)反(fan)饋(kui)造(zao)成的(de)。因(yin)為系(xi)(xi)(xi)統(tong)(tong)零點漂移,在(zai)正(zheng)反(fan)饋(kui)情(qing)況下(xia)(xia),就會迅速(su)(su)累加(jia)使電(dian)(dian)機(ji)在(zai)高速(su)(su)下(xia)(xia)運(yun)轉(zhuan),而(er)我(wo)(wo)們按標簽檢(jian)查(cha)線(xian)路后(hou)*正(zheng)確,機(ji)床(chuang)(chuang)廠技術(shu)人員(yuan)認(ren)為不(bu)可能接錯,在(zai)充分(fen)(fen)分(fen)(fen)析與檢(jian)測后(hou)我(wo)(wo)們將反(fan)饋(kui)線(xian)反(fan)接,結果(guo)機(ji)床(chuang)(chuang)運(yun)轉(zhuan)正(zheng)常。機(ji)床(chuang)(chuang)廠技術(shu)人員(yuan)不(bu)得(de)不(bu)承認(ren)德(de)方(fang)工(gong)作失誤(wu)。還(huan)有一(yi)例子,我(wo)(wo)們在(zai)天津某(mou)廠培訓講學時(shi),應廠方(fang)要求對他們廠一(yi)臺(tai)自進(jin)廠后(hou)一(yi)直(zhi)無(wu)(wu)法(fa)正(zheng)常工(gong)作的(de)精密(mi)磨床(chuang)(chuang)進(jin)行維修,其故(gu)(gu)障是(shi):機(ji)床(chuang)(chuang)一(yi)啟動(dong)電(dian)(dian)機(ji)就運(yun)轉(zhuan),而(er)且越來越快(kuai),直(zhi)至高轉(zhuan)速(su)(su)。我(wo)(wo)們分(fen)(fen)析認(ren)為是(shi)由(you)于(yu)速(su)(su)度(du)(du)環(huan)開(kai)路,系(xi)(xi)(xi)統(tong)(tong)漂移無(wu)(wu)法(fa)抑(yi)制(zhi)造(zao)成。經檢(jian)查(cha)其原因(yin)是(shi)速(su)(su)度(du)(du)反(fan)饋(kui)線(xian)接到了地(di)線(xian)上造(zao)成。③加(jia)工(gong)時(shi)工(gong)件表面(mian)達不(bu)到要求,走圓(yuan)弧插(cha)補軸換向(xiang)時(shi)出現凸臺(tai),或(huo)電(dian)(dian)機(ji)低速(su)(su)爬行或(huo)振動(dong),這類故(gu)(gu)障一(yi)般(ban)(ban)是(shi)由(you)于(yu)伺(si)服系(xi)(xi)(xi)統(tong)(tong)調整(zheng)不(bu)當,各軸增益系(xi)(xi)(xi)統(tong)(tong)不(bu)相(xiang)等或(huo)與電(dian)(dian)機(ji)匹配不(bu)合適引(yin)起,解決辦法(fa)是(shi)進(jin)行調節。④保險燒斷,或(huo)電(dian)(dian)機(ji)過熱,以至燒壞,這類故(gu)(gu)障一(yi)般(ban)(ban)是(shi)機(ji)械負載過大或(huo)卡死。
