Abstract

A motor control device includes: an X-axis detector; a Y-axis detector; a trajectory command generator that outputs a first position command and a second position command; an X-axis response correction unit that outputs a corrected position command; an X-axis position control unit that generates a first torque command; a Y-axis position control unit that generates a second torque command; a Y-axis measuring instrument that detects second machine end displacement; a Y-axis zero-point estimation unit that extracts characteristics of a zero point of a transfer function on the basis of the second torque command and the machine end displacement or on the basis of the second position command and the machine end displacement; and a response-correction-parameter determination unit that sets a response correction filter by using the characteristics of the zero point.
