The invention relates to a method for configuring a motorised drive device for a closure or solar protection unit, comprising at least the following steps: (E10) placing of the motorised drive device in a configuration mode; (E40) first movement of a screen towards its unwound position, by activation of the motorised drive device; (E50) automatic determination of a low end-of-travel position of the screen; (E80) movement of the screen towards its wound position, by activation of the motorised drive device; (E100) second movement of the screen towards its unwound position, by activation of the motorised drive device; and (E110) stopping of the motorised drive device at the low end-of-travel position of the screen determined during the automatic determination step (E50). The step comprising the automatic determination of the low end-of-travel position of the screen includes a sub-step (E500) for measuring the value of the electric current passing through the electric motor, performed by the measurement device, and a sub-step (E530) for determining a variation in the measured value.
