Thanks Dupre,
I think that these speeds are just some kind of reference for the pilots. It does not do anything.
Check this video:

At 10:30, you can see that selected speed = S speed
But I think the plane can go below S speed if the selected speed is (below it).
What do you think?
You had said for alpha floor:
"Note 2.αfloor is activated through the A/THR system, when:‐α is greater than αfloor (9.5 ° in configuration 0; 15 ° in configuration 1, 2; 14 ° in configuration 3; 13 ° in configuration FULL) or‐Sidestick deflection is greater than 14 ° nose up, with either the pitch attitude or the angle-of-attack protection active."
So you were talking about the flaps, isn't it? So for e.g, Alpha floor will activate if AoA = 9,5° if our flaps are retracted?
Thanks
