直流電機西門子調速器報警壞-解決全故障

 確認現場安全，啟動電機，利用(yong)STARTER的曲線(xian)跟蹤功(gong)能，記錄速(su)度和電流曲線(xian)，分析“動態響應"，進一(yi)步優化變頻器的運行。

主(zhu)要(yao)看啟動速(su)度(du)是否快，速(su)度(du)的(de)跟隨(sui)性是否好，當到達某(mou)一恒定(ding)速(su)度(du)時，看轉(zhuan)速(su)差和(he)電流(liu)，5分鐘后（可根據實際情況(kuang)），升速(su)到另一檔，繼(ji)續觀察速(su)度(du)和(he)電流(liu)，然(ran)后繼(ji)續，直(zhi)到最高速(su)，在這個(ge)過程中，不要(yao)出現(xian)速(su)度(du)偏差大，電流(liu)波(bo)動大的(de)情況(kuang)，然(ran)后停車(che)。

 第2步：啟動(dong)正向最高速，然(ran)后不停車，直(zhi)接(jie)給定低速，縮短加減速時(shi)間，看制動(dong)單元和制動(dong)電(dian)阻是(shi)否正常。

 第3步：拷貝優化后的曲線(xian)，以留備用（用來故(gu)障(zhang)分析對比）；

 第4步(bu)：調試完畢后，copy Ram to Rom ,防止(zhi)參(can)數(shu)掉電丟失；同時(shi)上裝參(can)數(shu)備(bei)份到(dao)PC。

(六) 變頻器的帶載運行

第1步： 利(li)用STARTER的曲線跟蹤功能，記錄速(su)度和電流曲線，分析“動態響應"，進(jin)一步優化變(bian)頻器的運(yun)行。

主要(yao)(yao)看啟動速(su)度(du)是(shi)否快，速(su)度(du)的(de)跟隨性是(shi)否好，不(bu)要(yao)(yao)出(chu)現(xian)速(su)度(du)偏差(cha)大，電流波動大的(de)情況。

         根據負載運行的(de)情況，手動(dong)優(you)化速(su)度(du)控制器的(de)PI參數。

 第2步：拷貝優化后(hou)的曲線，以留備(bei)用(yong)（用(yong)來故障分析對比）；

 第3步：在線(xian)修(xiu)改參(can)數(shu)(shu)后，copy Ram to Rom ,防止(zhi)參(can)數(shu)(shu)掉電丟失；同(tong)時上裝參(can)數(shu)(shu)備份到PC。
