a motor that moves the at least one strut;
a sequencer in electronic communication with the motor and directs operation of the motor;
an open input in communication with the sequencer to initiate an open signal to the sequencer;
a close input in communication with the sequencer to initiate a close signal to the sequencer;
wherein the door is moved by the at least one strut according to a plurality of velocities within a predetermined variance; and
wherein the sequencer monitors a distance of travel of the at least one strut and determines the distance of travel of the at least one strut relative to the plurality of velocities of the motor.
