Abstract:
An illustrative elevator system includes an elevator car, a machine including a motor that provides a motive force for moving the elevator car along a travel path and a brake that resists movement of the elevator car, and a brake controller. The brake controller is configured to determine when the elevator car is within a selected range of at least one end of the travel path. The brake controller inhibits a delay in application of the brake when the elevator car is within the selected range and permits a delay in application of the brake when the elevator car is outside of the selected range.
