Zusammenfassung:A method of learning a rescue time period by an elevator system (101). The elevator system (101) includes an elevator car (103) moved by a machine (111) and a machine brake (120), arranged such that braking of the machine (111) by the machine brake (120) brakes motion of the elevator car (103). The method includes releasing the machine brake (120) for at least one test time period, at the end of which the machine brake (120) is engaged, detecting a corresponding at least one maximum travel speed of the elevator car (103) reached as a result of releasing the machine brake (120) for each at least one test time period, checking whether each at least one maximum travel speed is an acceptable speed, and setting the rescue time period based upon said checking.
