Abstract
A motor control device includes an operation determination unit that determines whether a motor is in an operating state or in a stopped state based on an operation command signal or an operation signal and an amplitude estimation unit that, based on a determination result of the operation determination unit, sequentially estimates a vibration amplitude value from a control state quantity of a feedback control unit or a current control unit separately for a case where the motor is operated and a case where the motor is stopped and outputs the vibration amplitude value. A function of outputting an amplitude of a high-frequency vibration that occurs in a mechanical device including a control system as information useful for estimating an occurrence factor of the vibration is provided.
