Techniques including winding, by using an electric motor of the architectural covering, a blind of the architectural covering in a first direction. The techniques further include stopping the winding by the electric motor of the blind in the first direction at a programmatically adjustable wound end position. The techniques further include upon the blind reaching the programmatically adjustable wound end position, winding, by using the electric motor, the blind in an opposite direction to a second position relaxing at least a cord of the blind that is wound by a cord winding/unwinding unit driven by the electric motor, the difference between the programmatically adjustable wound end position and the second position being an amount less than that which would result in movement of the blind to a fully extended position and set based on a length of the blind.
