Roro control

Hi
Now I have a motorised roro roof I want to use sgp to do everything inc closing the roof at the end of sequence.
I want to know how sgp knows when to close the roof , I would park the mount first then close the roof - does it wait for the mount to report its parked or does it rely on the ascom driver from roof control to say its safe to close.
any ideas please
Thanks
Harry
