Abstract:
A method of operating an elevator system for a learn run sequence including the steps of moving, using a linear propulsion system, an elevator car through a lane of an elevator shaft at a selected velocity; detecting, using a sensor system, the location of the elevator car when it moves through the lane; controlling, using a control system, the elevator car, the control system being in operable communication with the elevator car, the linear propulsion system, and the sensor system; and determining, using the control system, a location of each of the car state sensors relative to each other within the lane in response to at least one of a travel time of the elevator car, a velocity of the elevator car, a position of the elevator car, and a height of the elevator car.
