The faders on the StudioLive AI and StudioLive Classic series mixers are not motorized. You can recall your stored fader position using Fader Locate Mode. If you recall a scene with Fader Recalling set to "yes", Fader Locate Mode will automatically be enabled and you can use the Fat Channel meters to recall your stored fader position.
StudioLive Series III Mixers feature motorized Faders.
