Abstract
A motor control device for controlling a servomotor, includes an inverter having multiple switching elements, a motor control unit configured to control switching operation of the multiple switching elements to thereby drive the servomotor, a brake configured to apply a braking force to the servomotor, a brake control unit configured to control the brake and a state acquisition unit configured to acquire a rotational state of the servomotor. The brake control unit actuates the brake when the rotation amount per unit time of the servomotor reaches a predetermined amount or greater in a state where the servomotor is not driven by the motor control unit and the brake is not operated.
