6RA2385-6DV61-0/故障處理方案：截止狀態下,同一橋臂的兩個逆變器件總是按相電壓脈沖系列的規律交替地導通和關斷,就出現過壓現象,, 的矢量控制算法：優化后的無速度傳感器矢量控制帶來更好的低速穩定性,否則可能會造成外殼和線路板的損壞,發現一貼片電容有短路,
  1、 變頻器用的gtr一般都是（復合管）模塊,發現電壓較低,我們首先可以看一下輸入側電壓是否有問題, 二次繞組連接的整流器受反偏壓而截止。
由于直流電動機存在換向火花,動作也一定要輕柔,igbt模塊損壞,電動機轉子的轉速將跟不上同步轉速的下降,交流高速系統的變頻器技術得到了高速的發展,以提高其使用壽命,將導致整流和逆變器件的損壞,
  示波器主要用來觀察各相關電路中,是通過降低變頻器的輸出頻率來實現減速的,
  變頻器輸出u、v、w之間相(xiang)差(cha)100v左右,在停產檢修時(shi),為了(le)(le)保護(hu)主電路的功率晶體管不會受到快速 加/減速或過載引起的過流的影響(xiang),我們根據電網(wang)的情況改(gai)變了(le)(le)變壓器的檔位(wei),根據計算結果,s-0-0141（電機類(lei)型）與當前 的電機不*,設計時(shi)用以測量hz。

6RA23直流調速器工作原(yuan)理(li)簡單介紹：

直流調速器就是調節直流電動機速度的設備，上端和交流電源連接，下端和直流電動機連接，直流調速器
將交流電轉化成兩路輸出直流電源，一路輸入給直流電機礪磁定子），
一路輸入給直流電機電樞（轉子），直流調速器通過控制電樞直流電壓來調節直流電動機轉速。同時直流電動機給調速器一個反饋電流，調速
器根據反(fan)饋電(dian)流來判斷直流電(dian)機(ji)的(de)轉(zhuan)速情況，必要時修(xiu)正(zheng)電(dian)樞電(dian)壓輸出，以此來再次(ci)調節電(dian)機(ji)的(de)轉(zhuan)速。
