M3控制器和三菱FR-SF-22K主軸控制器的數(shù)控機(jī)床，出現(xiàn)主軸噪聲較大，且在主軸空載情況下，負(fù)載表指示超過(guò)40%。 </p> <p> 分析與處理過(guò)程：考慮到主軸負(fù)載在空載時(shí)已經(jīng)達(dá)到40%以上，初步認(rèn)為機(jī)床機(jī)械傳動(dòng)系統(tǒng)存在故障。維修的*步是脫開(kāi)主軸的運(yùn)轉(zhuǎn)情況。 </p> <p> 經(jīng)試驗(yàn)，發(fā)現(xiàn)主軸負(fù)載表指示已恢復(fù)正常，但主軸仍有噪聲，由此判定該主軸系統(tǒng)的機(jī)械、電氣兩方面都存在故障。 </p> <p> 在機(jī)械方面，檢查了主軸機(jī)械傳動(dòng)系統(tǒng)，發(fā)現(xiàn)主軸轉(zhuǎn)動(dòng)明顯過(guò)緊，進(jìn)一步檢查發(fā)現(xiàn)主軸軸承已經(jīng)損壞，更換后，主軸機(jī)械傳動(dòng)系統(tǒng)恢復(fù)正常。 </p> <p> 在電氣方面，首先檢查了主軸驅(qū)動(dòng)器的參數(shù)設(shè)定，包括驅(qū)動(dòng)放大器的型號(hào)，的型號(hào)以及伺服環(huán)增益等參數(shù)，經(jīng)檢查發(fā)現(xiàn)機(jī)床參數(shù)設(shè)定無(wú)誤，由此判定故障原因是驅(qū)動(dòng)系統(tǒng)硬件存在故障。 </p> <p> 為了進(jìn)一步分析原因，維修時(shí)將主軸驅(qū)動(dòng)器的00號(hào)參數(shù)設(shè)定為1，讓主軸驅(qū)動(dòng)系統(tǒng)進(jìn)行開(kāi)環(huán)運(yùn)行，轉(zhuǎn)動(dòng)主軸后，發(fā)現(xiàn)噪聲消失，運(yùn)行平穩(wěn)，由此可以判定故障原因是在速度檢測(cè)器件PLG上。 </p> <p> 進(jìn)一步檢查發(fā)現(xiàn)PLG的安裝位置不正確，重新調(diào)整PLG安裝位置后，在進(jìn)行閉環(huán)運(yùn)行，噪聲消失。 </p> <p> 重新安裝與機(jī)械傳動(dòng)系統(tǒng)，機(jī)床恢復(fù)正常工作。 </p>
