西門子數控系統使能后控制器無輸出解決方法

三相(xiang)輸出正(zheng)常(chang)(chang)，但在(zai)低(di)速(su)時(shi)電(dian)(dian)(dian)(dian)動(dong)(dong)(dong)(dong)(dong)機抖(dou)動(dong)(dong)(dong)(dong)(dong)，無法(fa)進(jin)行(xing)正(zheng)常(chang)(chang)運行(xing)現象，首(shou)先估計多(duo)數為變(bian)頻(pin)器驅(qu)動(dong)(dong)(dong)(dong)(dong)電(dian)(dian)(dian)(dian)路(lu)(lu)損(sun)壞(huai)，正(zheng)確(que)的(de)解(jie)決(jue)辦(ban)法(fa)應該是確(que)定故障現象后(hou)將(jiang)變(bian)頻(pin)器打開，將(jiang)IGBT逆變(bian)模塊從印刷電(dian)(dian)(dian)(dian)路(lu)(lu)板上卸下(xia)，使(shi)用(yong)電(dian)(dian)(dian)(dian)子示(shi)波(bo)器觀察(cha)六(liu)路(lu)(lu)驅(qu)動(dong)(dong)(dong)(dong)(dong)電(dian)(dian)(dian)(dian)路(lu)(lu)打開時(shi)的(de)波(bo)形(xing)是否一致，找出不一致的(de)那一路(lu)(lu)驅(qu)動(dong)(dong)(dong)(dong)(dong)電(dian)(dian)(dian)(dian)路(lu)(lu)，更(geng)換該驅(qu)動(dong)(dong)(dong)(dong)(dong)電(dian)(dian)(dian)(dian)路(lu)(lu)上的(de)光耦(ou)，一般為PC923或者PC929，若變(bian)頻(pin)器使(shi)用(yong)年數超過(guo)3年，推薦(jian)將(jiang)驅(qu)動(dong)(dong)(dong)(dong)(dong)電(dian)(dian)(dian)(dian)路(lu)(lu)的(de)電(dian)(dian)(dian)(dian)解(jie)電(dian)(dian)(dian)(dian)容全部更(geng)換，然后(hou)再用(yong)示(shi)波(bo)器觀察(cha)，待六(liu)路(lu)(lu)波(bo)形(xing)一致后(hou)，裝上IGBT逆變(bian)模塊，進(jin)行(xing)負載實驗，抖(dou)動(dong)(dong)(dong)(dong)(dong)現象消除(chu)。

控制器出現變頻器輸出端打火故障現象，拆開檢查后發現IGBT逆變模塊擊穿，驅動電路印刷電路板嚴重損壞，正確的解決辦法是先將損壞IGBT逆變模塊拆下，拆的時候主要應盡量保護好印刷電路板不受人為二次損壞，將驅動電路上損壞的電子原器件逐一更換以及印刷電路板上開路的線路用導線連起來(這里要注意要將燒焦的部分刮干凈，以防再次打火)，再六路驅動電路阻值相同，電壓相同的情況下使用視波器測量波形，但變頻器一開，就報OCC故障(臺達變頻器無IGBT逆變模塊開機會報警)使用燈泡將模塊的P1和印板連起來，其他的用導線連，再次啟動還跳，確定為驅動電路還有問題，逐一更換光耦，后發現該驅動電路的光耦帶檢測功能，其中一路光耦檢測功能損壞，更換新的后，啟動正常。

西門子控制器黑屏一般故障原因有igbt短路造成內部保險燒毀、電源損壞等。控制面板pmu液晶顯示屏無顯示，用外接24v電源試機，屏幕顯示正常，再用萬用表測低壓交流輸出，無電壓說明故障在電源處，測uc3844(6)腳脈沖輸出正常，到q36柵極沒有，經表測量r321由28ω變為無窮大換新后試機，故障消失。
