描述
大多數(shù)變頻器容量可從3個角度表述：額定電流、可用電動機功率和額定容量。其中后兩項，變頻器生產廠家由本國或本公司生產的標準電動機給出，或隨變頻器輸出電壓而降低，都很難確切表達變頻器的能力。
機床電器檢查打開機床電控箱，檢查繼電器，接觸器，熔斷器，伺服電機速度，控制單元插座，主軸電機速度控制單元插座等有無松動，如有松動應恢復正常狀態(tài)，有鎖緊機構的接插件一定要鎖緊，有轉接盒的機床一定要檢查轉接盒上的插座，接線有無松動，有鎖緊機構的一定要鎖緊。CNC電箱檢查打開CNC電箱門，檢查各類接口插座，伺服電機反饋線插座，主軸脈沖發(fā)生器插座，手搖脈沖發(fā)生器插座，CRT插座等，如有松動要重新插好，有鎖緊機構的一定要鎖緊。按照說明書檢查各個印刷線路板上的短路端子的設置情況，一定要符合機床生產廠設定的狀態(tài)，確實有誤的應重新設置，一般情況下無需重新設置，但用戶一定要對短路端子的設置狀態(tài)做好原始記錄。接線質量檢查檢查所有的接線端子。包括強弱電部分在裝配時機床生產廠自行接線的端子及各電機電源線的接線端子，每個端子都要用旋具緊固一次，直到用旋具擰不動為止，各電機插座一定要擰緊。電磁閥檢查所有電磁閥都要用手推動數(shù)次，以防止長時間不通電造成的動作不良，如發(fā)現(xiàn)異常，應作好記錄，以備通電后確認修理或更換。限位開關檢查檢查所有限位開關動作的靈活及固定性是否牢固，發(fā)現(xiàn)動作不良或固定不牢的應立即處理。按鈕及開關檢查操作面板上按鈕及開關檢查，檢查操作面板上所有按鈕，開關，指示燈的接線，發(fā)現(xiàn)有誤應立即處理，檢查CRT單元上的插座及接線。地線檢查要求有良好的地線，測量機床地線，接地電阻不能大于1Ω。電源相序檢查用相序表檢查輸入電源的相序，確認輸入電源的相序與機床上各處標定的電源相序應絕對一致。選擇變頻器時，只有變頻器的額定電流是一個反映半導體變頻裝置負載能力的關鍵量。負載電流不超過變頻器額定電流是選擇變頻器容量的基本原則。需要著重指出的是，確定變頻器容量前應仔細了解設備的工藝情況及電動機參數(shù)，如潛水電泵、繞線轉子電動機的額定電流要大于普通籠型異步電動機額定電流，冶金工業(yè)常用的輥道用電動機不僅額定電流大很多，同時它允許短時處于堵轉工作狀態(tài)，且輥道傳動大多是多電動機傳動，應保證在無故障狀態(tài)下負載總電流均不允許超過變頻器的額定電流。
