4、抑制零漂
在閉環(huán)控制過程中，零漂的存在會對控制效果有一定的影響，最好將其抑制住。使用控制卡或伺服上抑制零飄的參數(shù)，仔細(xì)調(diào)整，使電機(jī)的轉(zhuǎn)速趨近于零。由于零漂本身也有一定的隨機(jī)性，所以，不必要求電機(jī)轉(zhuǎn)速絕對為零。
5、建立閉環(huán)控制
再次通過控制卡將伺服使能信號放開，在控制卡上輸入一個較小的比例增益，至于多大算較小，這只能憑感覺了，如果實(shí)在不放心，就輸入控制卡能允許的最小值。將控制卡和伺服的使能信號打開。這時，電機(jī)應(yīng)該已經(jīng)能夠按照運(yùn)動指令大致做出動作了。
