To provide a motor controller which realizes damping control in a motor servo controller which bears a speed control system without performing processing of a position command targeting damping of an end of a machine in a host system controller.SOLUTION: A motor controller receiving a speed command from a host system controller having a position controller, comprises: a position command estimating instrument which calculates an estimate of a position command based on the speed command and a motor shaft position response; and a speed command generator which generates an actual speed command so that an end of a machine connected with a motor does not vibrate based on the estimate, the motor controller outputting the actual speed command from the speed command generator to a speed controller.SELECTED DRAWING: Figure 1 【課題】機械の端部の制振を目的とした位置指令の加工を上位系制御装置内で行うことなく、速度制御系を担うモータサーボ制御装置内で制振制御を実現するモータ制御装置を提供することにある。【解決手段】位置制御器を有する上位系制御装置からの速度指令を受けとるモータ制御装置であって、速度指令とモータ軸位置応答とに基づいて、位置指令の推定値を算出する位置指令推定器と、推定値に基づいて、モータに接続された機械の端部が振動しないような実速度指令を生成する速度指令生成器とを有し、速度指令生成器から速度制御器に実速度指令を出力するモータ制御装置。【選択図】図１
