The present invention relates to an apparatus and method for driving a moveable closure, such as a garage door. In an initialisation process in a setup mode for the door operator for driving a moveable closure between open and closed positions, the apparatus allows selection of opening and/or closing speeds for the closure from a plurality of predefined stored driving speeds. This selection, or the range of stored driving speeds available for selection, is made in accordance with the type of closure to be driven, and this may be established automatically by detecting certain characteristics of movement of the closure as part of the initialisation process.
