1. A modular drive assembly for a sliding door, comprising: a guide track having a hinge assembly slidably received therein; a pair of pulleys disposed on either end of said guide track, said pair of guide pulleys being disposed adjacent to a path of travel of said hinge assembly within said guide track, said path of travel being defined by a closed door limit and an open door limit; and a pair of cables each having an end that is secured to said hinge assembly and the other end is secured to a cable drum of a motor drive unit mounted to said guide track, said motor drive unit being configured to rotate said cable drum, wherein said cable drum is also capable of freely rotating within said motor drive unit when said motor drive unit is not rotating said cable drum, wherein rotation of said cable drum causes said hinge assembly to move in said guide track as one of said cables wraps onto said cable drum while the other one of said cables wraps off of said cable drum, wherein said hinge assembly passes a portion of one of said pair of pulleys when said hinge assembly is at said closed door limit and said hinge assembly passes a portion of the other one of said pair of pulleys when said hinge assembly is at said open door limit.
