變頻器在數(shù)控車床的應用，其中變頻器與數(shù)控裝置的聯(lián)系通常包括：(1)數(shù)控裝置到變頻器的正反轉信號;(2)數(shù)控裝置到變頻器的速度或頻率信號;(3)變頻器到數(shù)控裝置的故障等狀態(tài)信號。因此所有關于對變頻器的操作和反饋均可在數(shù)控面板進行編程和顯示。

2.2 主軸變頻控制的系統(tǒng)構成
不使用變頻器進行變速傳動的數(shù)控車床一般用時間控制器確認電機轉速到達指令速度開始進刀，而使用變頻器后，機床可按指令信號進刀，這樣一來就提高了效率。如果被加工件如圖2(1)所示所示形狀，則由圖2(1)中看出，對應于工件的ab段，主軸速度維持在1000rpm，對應于bc段，電機拖動主軸成恒線速度移動，但轉速卻是聯(lián)系變化的，從而實現(xiàn)高精度切削。
