PROBLEM TO BE SOLVED: To suppress the resonance of a device, equipped with a movable part, due to a shock in acceleration or deceleration. SOLUTION: The numerical controller is equipped with a vibration detection part 7 which detects the vibration of the device equipped with the movable part. Position command arithmetic parts (2A, 2B, and 2C) control servomotors (5A, 5B, and 5C) so that when the vibration detection part 7 detects the resonance of the device equipped with the movable part, the movable part operates with acceleration different from the acceleration in operation based upon previously set numerical data. Consequently, the resonance of the device, equipped with the movable part, due to the shock in acceleration or deceleration is suppressed.
