伺服電機(jī)運(yùn)行時(shí)出現(xiàn)異常聲音或抖動(dòng)現(xiàn)象，如何處理?①伺服配線: a.使用標(biāo)準(zhǔn)動(dòng)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(dòng)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(dòng)，切實(shí)保證接地良好。② 伺服參數(shù): a.伺服增益設(shè)置太大，建議用手動(dòng)或自動(dòng)方式重新調(diào)整伺服參數(shù); b.確認(rèn)速度反饋濾波器時(shí)間常數(shù)的設(shè)置，初始值為 0，可嘗試設(shè)置值; c.電子齒輪比設(shè)置太大，建議恢復(fù)到出廠設(shè)置: d.伺服系統(tǒng)和機(jī)械系統(tǒng)的共振，嘗試調(diào)整陷波濾波器頻率以及幅值。③機(jī)械系統(tǒng): a.連接電機(jī)軸和設(shè)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(huì)導(dǎo)致負(fù)載轉(zhuǎn)矩變動(dòng)，嘗試空載運(yùn)行，如果空載運(yùn)行時(shí)正常則檢查機(jī)械系統(tǒng)的結(jié)合部分是否有異常 c.確認(rèn)負(fù)載慣量，力矩以及轉(zhuǎn)速是否過大，嘗試空載運(yùn)行，如果空載運(yùn)行正常，則減輕負(fù)載或更換更大容量的驅(qū)動(dòng)器和電機(jī)。410-4 MODICON CONTROLLERS REMANUFACTURED
