Patent ID: 8789660

Claim:
Elevator system, which comprises: an elevator car; a counterweight; a motor drive for moving the elevator car according to a movement profile to be determined for the movement of the elevator car; wherein the loading of the aforementioned motor drive is arranged to be limited to the limit value for the maximum permitted loading by reducing the maximum instantaneous acceleration of the elevator car or the maximum instantaneous deceleration of the elevator car in the movement profile of the elevator car, when loaded to be heavier than a balanced load, in relation to the maximum instantaneous acceleration/maximum instantaneous deceleration of the elevator car when situated higher up and loaded in a corresponding manner, and the loading of the aforementioned motor drive is further arranged to be limited to the limit value for the maximum permitted loading by reducing the maximum instantaneous acceleration of the elevator car or the maximum instantaneous deceleration of the elevator car in the movement profile of the elevator car, when loaded to be lighter than the balanced load, in relation to the maximum instantaneous acceleration/maximum instantaneous deceleration of the elevator car when situated lower down and loaded in a corresponding manner.
