1. A surgical instrument, comprising:

  • an end effector;

    a drive member movable to effectuate a motion in said end effector;

    a motor operable to move said drive member to effectuate said motion in said end effector; and

    a bailout assembly operable to perform a mechanical bailout of said surgical instrument in response to a bailout error, said bailout assembly comprising;

    a bailout door;

    a bailout handle accessible through said bailout door, said bailout handle operable to move said drive member to effectuate a bailout motion in said end effector; and

    a controller, comprising;

    a memory;

    a processor coupled to said memory, said processor configured to detect said bailout error, wherein said processor is programed to stop said motor in response to said detection of said bailout error; and
