The acceleration feedback control is executed only when the moving command is zero, and also, the speed feedback quantity is smaller than a set value (np), and a rotation of a servomotor is considered to be stopped. In such a way, while the rotation of the servomotor is stopping, generation of vibration is suppressed, and stability of a system which is stopping is improved.
