Abstract
A method for controlling a shading device includes: moving a screen by electrical activation of an electromechanical actuator; determining a value of data representing operation of a motorised drive device during screen movement; and comparing the determined data to a first predetermined threshold. Depending on the result, the method includes: reducing a rotational speed setpoint of an output shaft of the electromechanical actuator if the value of the determined data≥the value of the first predetermined threshold, to reduce power consumed by the electromechanical actuator; or maintaining the rotational speed setpoint of the output shaft of the electromechanical actuator as long as the determined data<the value of the first predetermined threshold. The determined data is the power consumed or the torque delivered by the electromechanical actuator. The determining, comparing, and reducing are iterated until a value of a second predetermined speed threshold is reached.
