If speed is selected as mechanical input in specialized power electronics asynchronous block, option to specify inertia constant and friction factor will disappear. Then how to specify rotor inertia?

If speed is your input variable, then you are defining what the speed will be. Thus, modeling the inertia and friction internally have no meaning. If you wish to take these into account you must do this externally where you are calculating the speed.
