Abstract
This disclosure discloses a motor control device including a main circuit, a voltage detector, and a controller. The controller includes a position controller and a speed controller, The position controller generates a speed command. The speed controller generates a torque command and controls a inverter based on the torque command. Further, the controller includes a torque limiter, and a speed matching instruction part. The torque limiter starts torque limiting by the torque command to a predetermined torque or less and cancels the torque limiting. The speed matching instruction part matches the speed command with a first position command speed after the cancellation of the torque limiting. The holding part calculates and holds an accumulated position deviation.
