Methods for configuring and controlling the operation of a motorised drive device for a home automation unit, and associated unit and motorised drive device

A method for configuring a motorized drive device for a solar protection home automation unit,

• the solar protection home automation unit comprising a shading device,
• the shading device comprising at least:
• a winding tube,
• a screen, a first end of the screen being fastened to the winding tube,
• a bar, a second end of the screen being fastened to the bar, and
• at least two arms, a first end of each of the arms being fastened to the bar and a second end of each of the arms being fastened to a support structure of the shading device,
• the motorized drive device comprising at least:
• an electromechanical actuator making it possible to wind and unwind the screen on the winding tube, and to fold and unfold the arms,
• the electromechanical actuator comprising at least:
• an electric motor,
• an output shaft connected to the winding tube of the shading device, and
• an electronic control unit,
• the electronic control unit comprising at least:
• a device for measuring a property of an electric current traversing the electric motor, and
• a memory storing at least one value of the measured property,
• wherein said method comprises at least the following steps:
• a first step for triggering the winding of the screen, from an unwound position, in which the screen is relaxed, to a wound position,
• a second step for measuring the property of the electric current traversing the electric motor via the measuring device,
• a third step for determining a first maximal value of the measured property, the first maximal value being representative of a breakage position of the arms of the shading device, and
• a fourth step for determining a lower end-of-travel position of the screen,
• where the lower end-of-travel position of the screen corresponds to a value of the measured property below the first maximal value, and
• where the lower end-of-travel position of the screen is located before the breakage position of the arms of the shading device, in the unwinding direction of the screen.
