This invention relates to a method for defining absolute position information of an elevator car. The method comprises: obtaining continuously a pulse position information of the elevator car; and defining an absolute position information of the elevator car by adding a predefined correction value to the obtained pulse position information of the elevator car. The predefined correction value indicates a drift between the obtained pulse position information of the elevator car and the actual pulse position of the elevator car. The invention also relates to a safety control unit and an elevator system performing at least partly the method.
