Abstract
In various embodiments, a fastening assembly comprising a first jaw, a second jaw, a closure member, a rotatable drive shaft, a firing member, an electric motor, a sensing device, and a control system is disclosed. The second jaw is movable between an open position and a closed position relative to the first jaw. The closure member is movable between a first position and a second position. The second jaw is in the closed position when the closure member is in the second position. The electric motor is operable to rotate the rotatable drive shaft and advance the firing member through a firing stroke. The sensing device is configured to sense when the closure member is in the second position. The control system is configured to prevent advancement of the firing member through the firing stroke until after the second jaw is in the closed position.
