Summary:PROBLEM TO BE SOLVED: To provide a current command table automatic generation system capable of automatically generating d-axis and q-axis current command values with high accuracy on the basis of an actual value.SOLUTION: A system for automatically generating a current command table for converting a torque command to be given to an inverter 40 for performing variable speed control of an embedded magnet synchronous motor 10 into d-axis and q-axis current command values includes a current command table automatic generation device 30 which causes a load servo device 20 to perform speed control, performs torque feedback control so as to cause a torque detection value to coincide with a torque command value set at one operation point to generate a q-axis current command value, retrieves and generates a d-axis current command value for satisfying desired performance on the basis of various information of the current command table automatic generation system in a state undergoing the torque feedback control, and associates the d-axis current command value and the q-axis current command value generated about the entire operation points with a revolution speed and the torque, respectively to make a table.SELECTED DRAWING: Figure 1 【課題】ｄ軸・ｑ軸電流指令値を、実測値に基づいて高精度かつ自動的に生成することができる電流指令テーブル自動生成システムを提供する。【解決手段】埋込磁石同期モータ１０を可変速制御するインバータ４０に与えるトルク指令から、ｄ軸、ｑ軸電流指令値に変換する電流指令テーブルを自動生成するシステムであって、負荷サーボ装置２０に対して速度制御を行わせ、トルク検出値が一つの動作点で設定されたトルク指令値に一致するようにトルクフィードバック制御を行ってｑ軸電流指令値を生成し、トルクフィードバック制御がなされている状態で、電流指令テーブル自動生成システムの各種情報に基づいて所望の性能を満たすｄ軸電流指令値を探索して生成し、全動作点について生成されたｄ軸電流指令値およびｑ軸電流指令値を、回転数とトルクに各々対応付けてテーブル化する電流指令テーブル自動調整装置３０を備えた。【選択図】図１
