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.

The inventive method makes it possible to feed an alternating current electric motor used for operating a rolling shutter in a building by means of a gear whose performance substantially varies when a movable element drives or is driven by the rolling shutter. The electric motor is supplied, in certain phases, at a reduced tension, wherein the motor slipping measuring a relative speed deviation with respect to a zero running torque speed remains less the motor slipping when the rotor thereof ruts at a nominal speed at least if the rolling shutter does not meet obstacles. The drive for the rolling shutter for carrying out said method is also disclosed.

In the initialization process for the control of the movement of a motorized roller shutter, the travel of the shutter between its two extreme positions is divided into different segments and each segment end is allocated a duration of shutter movement in a first direction between this segment end and a first reference position and a duration of shutter movement in a second direction between this segment end and a second reference position.

Process for initializing a motorized roller shutter

A process for initializing a motorized roller shutter that moves between two extreme positions includes moving the shutter in a first direction at fast speed, then moving it at slow speed, then reversing it in a second direction at fast speed followed by slow speed. The shutter is moved back in the first direction at fast speed, then at slow speed, after which the times are determined that are needed to cover the full travel at fast speed between the two extreme positions in the first direction and in the second direction.
