The invention relates to a method and also to a safety arrangement for monitoring the movement of an elevator component, more particularly of an elevator car (1) or of the automatic door (10) of an elevator. In the method a setup drive of an elevator component (1, 10) is run, and the speed and/or acceleration of the elevator component (1, 10) is measured during the setup drive, a threshold value (2, 3) for the speed and/or acceleration of the elevator component (1, 10) is formed on the basis of the measuring data (4, 5) obtained in the setup drive, the speed and/or acceleration of the elevator component (1, 10) is measured, and if the measured speed and/or acceleration exceeds the aforementioned threshold value (2, 3), a monitoring signal (6) for bringing the elevator to a safe state is formed. |
