By providing a configuration for calculating motor control constants to be set in a motor control apparatus automatically on the basis of a target response time constant obtained from a target response time constant input unit, waveform parameters obtained from a waveform parameter input unit, a normalized time constant obtained from a normalized time constant calculation unit, and a motor load inertia obtained from a motor load inertia input unit, it is possible to obtain a motor control constant calculation device that can determine appropriate motor control constants for obtaining a desired response characteristic by automatic calculation while avoiding variation and an increase in the number of steps due to differences in the abilities of users.
