取決于脈沖頻率的電流降額
為了降低電機噪聲或提高輸出頻率,可相對于出廠設(shè)定值(1.25 kHz 或 2 kHz)來提高脈沖頻率。如果脈沖頻率增加,則必須考慮輸出電流的降容系數(shù)。必須將此降額系數(shù)應(yīng)用于技術(shù)數(shù)據(jù)中規(guī)定的電流。
有關(guān)詳細資料,請參閱《SINAMICS 低壓工程手冊》。

注:
通過直線插補,可以確定介于固定值之間的范圍內(nèi)的脈沖頻率降額因子。
例如,SINAMICS G130 調(diào)速柜具有用于克服起步轉(zhuǎn)矩的過載容量。如果存在更大的峰值負載,那么必須在組態(tài)時考慮這種情況。因此,在具有過載要求的驅(qū)動器中,必須將合適的基本負載電流用作所需負荷的基礎(chǔ)。
過載的標準是:在過載發(fā)生前后,變頻調(diào)速器以基準負載電流工作,負載的周期為 300s。
基于負載電流低負荷 IL,允許 110 % 的過載 60 s 或 150 % 用于 10 s。
基于負載電流高負荷 IH,允許 150 % 的過載 60 s 或 160 % 用于 10 s。
