Method for adjusting a system having a motorised windable element and system having a motorised windable element implementing said method

A method for adjusting a system, having a motorized windable element, said system comprising:

• a windable element,
• a winding tube, onto which said windable element can be wound,
• an actuator for operating the windable element, comprising an electric motor, which is movable in a first direction of rotation in which the windable element is displaced in at least one unwinding direction, and in a second direction of rotation in which the windable element is displaced in at least one winding direction,
• an electronic control unit comprising a tracking device for tracking the position of the windable element,
• said windable element being configured to reach a high position and a low position located beyond said high position in the unwinding direction of the windable element, the windable element being wound at least partially around the winding tube in the lower position,
• the said method comprising a step wherein the tracking device tracks a single position known as the windable element replacement position, according to which the windable element is completely unwound relative to the winding tube.
