摘要

The method involves shifting measurement referential when an electric motor (3) is stopped on effort in interval of displacement units before an electronic control unit (4) e.g. electronic card, measures displacement corresponding to displacement unit values, so that difference between the values remains constant. One of the values permits a mobile unit (2) i.e. apron, to attain a position, where the mobile unit is in stop moment of the motor from a reference position of the mobile unit.
