三菱伺服電機運行時抖動現(xiàn)象可能的幾個原因:1、伺服負載過大(伺服選小了) 2、伺服剛性沒調(diào)好 3、絲桿沒選好 。下面我們從伺服配線、伺服參數(shù)、機械系統(tǒng)三個方面更詳細的分析。
一、 伺服配線:
a.使用標準動力電纜,編碼器電纜,控制電纜,電纜有無破損;
b.檢查控制線附近是否存在干擾源,是否與附近的大電流動力電纜互相平行或相隔太近;
c.檢查接地端子電位是否有發(fā)生變動,切實保證接地良好。~~~~~~~~~~~~~~~~~~~~~~~~~~~~

二、伺服參數(shù):
a.伺服增益設置太大,建議用手動或自動方式重新調(diào)整伺服參數(shù);
b.確認速度反饋濾波器時間常數(shù)的設置,初始值為0,可嘗試增大設置值;
c.電子齒輪比設置太大,建議恢復到出廠設置;
d.伺服系統(tǒng)和機械系統(tǒng)的共振,嘗試調(diào)整陷波濾波器頻率以及幅值。
三、機械系統(tǒng):
a.連接電機軸和設備系統(tǒng)的聯(lián)軸器發(fā)生偏移,安裝螺釘未擰緊;
b.滑輪或齒輪的咬合不良也會導致負載轉(zhuǎn)矩變動,嘗試空載運行,如果空載運行時正常則檢查機械系統(tǒng)的結(jié)合部分是否有異常;
c.確認負載慣量,力矩以及轉(zhuǎn)速是否過大,嘗試空載運行,如果空載運行正常,則減輕負載或更換更大容量的驅(qū)動器和電機。
