位置前饋增益
1、設定位置環的前饋增益;
2、設定值越大時,表示在任何頻率的指令脈衝下,位置滯後量越小;
3、位置環的前饋增益大,控制係統的高速響應特性提高,但會使係統的位置不穩定,容易產生振蕩;
4、不需要很高的響應特性時,本參數通常設為0表示範圍:0~100%。

主機箱內係統版,軟盤,硬盤驅動及各種適配器擴展卡等係統部件使用。通俗來講就是,一個電源壞了,另一個備份電源代替其供電。可以通過為節點和磁盤提供電池後援來增強硬件的可用性。
HP 支持的不間斷電源(UPS),如 HP PowerTrust,可提防瞬間掉電。磁盤與供電電路的連接方式應使鏡像副本分別連接到不同的電源上。根磁盤與其相應的節點應由同一電源電路供電。特別是,群集鎖磁盤(當重組群集時用作仲裁器)應該有冗餘電源,或者,它能由群集中節點之外的電源供電。
