A power pack is removably loadable into the compartment, the power pack having one or both of a) a first motor and a first engagement member removably engageable with the firing mechanism when the power pack is loaded into the compartment to effect movement of the firing mechanism; and b) a second motor and a second engagement member removably engageable with an articulating mechanism in the housing of the surgical fastener applier to effect movement of an articulation mechanism to effect articulation. One or both of a firing position and an articulation position are tracked during the surgical procedure. Sensors are provided to detect select parameters and instrument functions.
