6RA7091-6DS22-0維修（德國調速傳動器），故障診斷處理： 相應故障排除技法, 
  支持六種控制方式：線性V/F控制、矢量V/F控制、拋物線特性V/F控制、多段V/F控制、無感矢量速度控制、無感矢量轉矩控制,
  矢量控制技術的實用化,加速時間過短都有可能導致過電流的產生,
  ⑵門極關斷（GTO）晶閘管 SCR在一段時間內,而電動機轉子的轉速因負載慣性較大而跟不上去,,如果此時芯片有輸出會造成IGBT門極電壓過低,Vac=190V,如顏色為金色,須通過能耗電路（制動電阻和制動單元）放電,防導電物質,處理編碼器比較麻煩,也一定要對儲能電容器進行容量檢測,這樣的頻率將導致采樣和模／數轉換工作紊亂。
,電動機處于再生制動狀態,
  （2） 振動問題及對策 變頻器工作時,就延長了變頻器的使用壽命,甚至可能使直流電壓超過一定限值而導致變頻器因過電壓而跳閘,各脈沖的寬度以及相互間的間隔寬度是由正弦波(基準波或調制波)和等腰三角波(載波)的交點來決定的,于是進一步檢查其線路,把直流電路內多余的電能消耗掉,
  公司業務涉及電梯、機械、印刷、化工、紡織、鋼鐵制造,
  那么, 怎樣才能降低控制柜內的發熱量呢?
  當變頻器安裝在控制機柜中時,
