    Abstract: A feed apparatus has a ball screw, a nut, a drive motor, a braking mechanism and a controller and moves a movable body vertically. When recognizing a movement command for rapid traverse relating to the movable body, the controller, when the movable body is to be moved upward, moves the movable body past a target position according to the movement command and then reverses the moving direction thereof and moves the movable body to the target position and stops it there, and, when the movable body is to be moved downward, moves the movable body directly to the target position and stops it there. After moving the movable body to the target position and stopping it there, the controller causes the drive motor to keep the position of the movable body at the stop position and causes the braking mechanism to brake the movement of the movable body.
