3、試方向
對于一個閉環(huán)控制系統(tǒng)，如果反饋信號的方向不正確，后果肯定是災(zāi)難性的。通過控制卡打開伺服的使能信號。這是伺服應(yīng)該以一個較低的速度轉(zhuǎn)動，這就是傳說中的“零漂”。一般控制卡上都會有抑制零漂的指令或參數(shù)。使用這個指令或參數(shù)，看電機的轉(zhuǎn)速和方向是否可以通過這個指令（參數(shù)）控制。如果不能控制，檢查模擬量接線及控制方式的參數(shù)設(shè)置。確認(rèn)給出正數(shù)，電機正轉(zhuǎn)，編碼器計數(shù)增加；給出負(fù)數(shù)，電機反轉(zhuǎn)轉(zhuǎn)，編碼器計數(shù)減小。如果電機帶有負(fù)載，行程有限，不要采用這種方式。測試不要給過大的電壓，建議在1V以下。如果方向不一致，可以修改控制卡或電機上的參數(shù)，使其一致。
