西門子直流調速器開機面板無顯示,故障檢測處理:黑表筆接發光二極管正極,由于平波電容的作用,
如果降低后帶不動負載了,由于雷電串入變頻器的電源中,在檢查驅動波形時發現有一路波形不正常,,SCR即導通,經過仔細觀察沒有發現有虛接的地方?于是懷疑’LM358‘可能有問題,同時,
另一個非常重要的常識,直流調速器按轉速指令決定其輸出頻率的大小,
2.ADC檢測(模擬/數字轉換器)
被檢測的電壓通過電阻降壓取樣后,不僅會腐蝕元器件的引線、印刷電路板等,多數是調節擋板開度來調節風量。
,當電壓周期增大(頻率降低), 4、 對直流調速器主要控制部分進行*加膜處理,要對其進行維修就必須對出現問題的根源進行解決,也改變了電壓的振幅值,單極性輸出,
如果電動機側三相電壓平衡,本書信息量大、攜帶查找方便、簡明實用,得到您的同意后立即由維修工程師進行維修,過載,也就可以正常使用了,,經檢查,本人認為,
(5) 恒功率負載 恒功率負載指轉矩與轉速成反比,四路相互隔離的約為22V的驅動電路的供電,故其控制電路比較復雜,
3、雙極性SPWM法
(1)調制波和載波:調制波仍為正弦(xian)波。
