西門子變頻器MM430開機操作面板無反應；西門(men)子MM430變(bian)頻器(qi)送電后(hou)屏(ping)幕不亮(liang)黑屏(ping)，西門(men)子交流變(bian)頻調速(su)器(qi)維修故(gu)障分(fen)析(xi)；

變頻器面板無顯(xian)示有(you)可能是下面幾種(zhong)情況：

有可能通電無顯示故障:降(jiang)壓(ya)電阻老化損壞開路，致使(shi)高壓(ya)直流(liu)電未能加到脈(mo)沖變壓(ya)器的初級繞組上。開關電源無法工(gong)作，整個變頻(pin)器無低壓(ya)直流(liu)供電，出現無顯示故障。

解(jie)決(jue)方(fang)法：更換降壓電阻(zu)。

2. 沒有(you)任何顯(xian)示，黑屏，由(you)于(yu)器(qi)件(jian)老化(hua)造(zao)成(cheng)。

解(jie)決方(fang)法(fa)：更MOS管，二(er)極管，變頻器恢(hui)復工作。

3.  開(kai)關(guan)電源電路不正常工作。

解決方法：需要更換已(yi)壞(huai)的無器件即可正常(chang)工作(zuo)。

4. 變頻器(qi)使(shi)用時間較久造(zao)成老化。

解(jie)決方(fang)法：更換變壓器即可。

5. 用戶可能在使(shi)用變頻(pin)器時，經(jing)常帶電扒(ba)插操作(zuo)面板，造成主控板上的芯片損壞。

解決方法：更換芯片即可。

我們主要做變頻器維修等業務，所以對變頻器、伺服系統等產品比較關注；我們發現很多工廠的變頻器放置時間半年以上再使用，由于放置環境不好、變頻器使用年限過長等因素，損壞的幾率比較高，一般會出現：送電后，面板無顯示、炸機或者其他故障。

為什么會出現面板無顯示、炸機故障等現象呢？

根據我們的經(jing)驗主要有以下2個原因：

1、放置環境太差，會有大(da)量的粉塵和工業污染等(deng)；

2、長時間不(bu)通電(dian)(dian)，會導致電(dian)(dian)解電(dian)(dian)容(rong)內的(de)電(dian)(dian)解液干涸，使容(rong)量下降、漏電(dian)(dian)增大。

這樣在(zai)變頻器送電時(shi)，就會(hui)出現面板無(wu)顯(xian)示、炸機或者其他故障。

所以(yi)變頻(pin)器如(ru)果(guo)(guo)不用(yong)的話，存(cun)放環(huan)境一定要找好的地方，最(zui)好能包(bao)裝密封起(qi)來，如(ru)果(guo)(guo)有條(tiao)件可以(yi)存(cun)儲在(zai)低溫環(huan)境下。

還(huan)有就(jiu)是定期使用(yong)(yong)專用(yong)(yong)設備給變(bian)頻器充電，并檢(jian)測I/O端口，這樣更加安全放心。
