Beschreibung
Zusammenfassung:	One aspect of the present invention is a conveyance method of conveying a conveyance target object by loading the conveyance target object on a slider, characterized in that the slider is connected to a ball nut threadably engaged with a ball screw shaft, and the conveyance method comprises a step of rotating the ball screw shaft by an electric motor, a step of applying a braking force which is a rotation resistance to the ball screw shaft by a non-electric resistance changing unit, and a step of setting at least one of a driving torque of the electric motor and the braking force of the resistance changing unit so that the slider will stop when a predetermined external force acts on the slider during conveyance and changes the slider to an overload state regardless of the presence/absence of the conveyance target object loaded on the slider and a weight of the conveyance target object.
