西(xi)(xi)門(men)(men)子伺(si)服(fu)控制(zhi)器(qi)(qi)是(shi)一(yi)(yi)種高性能(neng)的(de)(de)電(dian)(dian)(dian)氣控制(zhi)設(she)備(bei)(bei)，在機械制(zhi)造(zao)、自動化生產(chan)線和(he)工業控制(zhi)等領域得到(dao)了廣泛應用。然而，隨著使用時間的(de)(de)增加和(he)設(she)備(bei)(bei)使用環境的(de)(de)變化，可能(neng)會出現一(yi)(yi)些問(wen)(wen)題(ti)(ti)。下(xia)面(mian)我們來詳細了解一(yi)(yi)下(xia)西(xi)(xi)門(men)(men)子伺(si)服(fu)控制(zhi)器(qi)(qi)維修(xiu)中常見的(de)(de)問(wen)(wen)題(ti)(ti)及解決方法。一(yi)(yi)、電(dian)(dian)(dian)源(yuan)(yuan)故(gu)障(zhang)電(dian)(dian)(dian)源(yuan)(yuan)故(gu)障(zhang)是(shi)西(xi)(xi)門(men)(men)子伺(si)服(fu)控制(zhi)器(qi)(qi)維修(xiu)中常見的(de)(de)問(wen)(wen)題(ti)(ti)之一(yi)(yi)。可能(neng)是(shi)供電(dian)(dian)(dian)電(dian)(dian)(dian)壓不(bu)穩定、開關(guan)電(dian)(dian)(dian)源(yuan)(yuan)故(gu)障(zhang)、電(dian)(dian)(dian)源(yuan)(yuan)線路接觸不(bu)良(liang)等原(yuan)因引起。解決方法是(shi)檢查(cha)供電(dian)(dian)(dian)電(dian)(dian)(dian)壓是(shi)否(fou)穩定、更換開關(guan)電(dian)(dian)(dian)源(yuan)(yuan)或(huo)修(xiu)復電(dian)(dian)(dian)源(yuan)(yuan)線路接觸不(bu)良(liang)。二、通訊故(gu)障(zhang)西(xi)(xi)門(men)(men)子伺(si)服(fu)控制(zhi)器(qi)(qi)通常需要與其他設(she)備(bei)(bei)進行通訊，...2023-02-15
在(zai)許多場合(he)，因為西(xi)門子伺(si)服(fu)(fu)(fu)驅動器(qi)的電流(liu)(liu)電壓較(jiao)高，比如有的伺(si)服(fu)(fu)(fu)驅動器(qi)較(jiao)大輸出電流(liu)(liu)8A，電壓325V，再加(jia)上其(qi)外殼(ke)未采用鋁合(he)金外殼(ke)進行(xing)磁(ci)屏(ping)蔽，因此對高靈敏(min)的接收機(ji)系(xi)統造(zao)(zao)成干(gan)擾，使其(qi)無法(fa)工(gong)作，并且干(gan)擾電源，尤其(qi)在(zai)高頻時，可能造(zao)(zao)成控制系(xi)統的單片(pian)機(ji)和上位機(ji)無法(fa)進行(xing)正(zheng)常(chang)通(tong)訊，給正(zheng)常(chang)使用造(zao)(zao)成了困難，因此干(gan)擾問題必須加(jia)以解(jie)決。下面我(wo)們來介紹一(yi)些(xie)解(jie)決伺(si)服(fu)(fu)(fu)驅動器(qi)干(gan)擾問題的方法(fa)。1.加(jia)裝(zhuang)電源濾波器(qi)，減少(shao)對交(jiao)流(liu)(liu)電源的污(wu)染(ran)2.一(yi)點接地原則。將電源濾波器(qi)的地、驅動器(qi)PE(地)(伺(si)服(fu)(fu)(fu)驅動器(qi)與機(ji)箱底(di)板絕(jue)緣(yuan))...2022-08-29
