Abstract
In an elevator device, movement of a car is braked by a brake device in a state in which driving of a hoist is stopped. While the drive of the hoist is stopped, braking force of the brake device is controlled by a brake control device based on a signal from a movement detector that generates a signal corresponding to movement of the car. The brake control device generates a target pattern for at least one of speed and acceleration of the car and controls braking force of the brake device such that the movement of the car follows the target pattern.
