Abstract
A method and a system determine a position of at least one sway sensor in an elevator system for sensing a lateral motion of an elevator rope between a first boundary location and a second boundary location. An operation of the elevator system is simulated with a model of the elevator system to produce an actual shape of the elevator rope caused by the operation. At least one sway location is determined, such that an error between the actual shape of the elevator rope and an estimated shape of the elevator rope is minimized. The estimated shape of the elevator rope is determined by interpolation of the first boundary location, the second boundary location, and the sway location. The position of the sway sensor is determined, such that the sway sensor senses the lateral motion of the elevator rope at the sway location.
