A300-B1/B2/B2K/B4 have Inboard "All Speed" Ailerons and outboard "Low Speed" Ailerons. The Low Speed Ailerons are connected when the Slats are extended, and work with the All Speed ailerons.
When the slats are retracted they are disconnected and remain in the neutral (0 degrees) position.
The A300-600 (Actually A300-B4-600) has a fixed trailing edge instead of the outboard ailerons.
Hope this helps.
