A surgical stapling system comprising a motorized system configured to generate a low torque rotary motion during a first operating mode and a high torque rotary motion during a second operating mode, a control system configured to switch between the first and second operating modes, an end effector, a drive member, and a rotatable member operably coupled with the motorized system and in operable engagement with the drive member is disclosed. The end effector comprises a first jaw and a second jaw movable relative to the first jaw between an open position and a clamped position. The high torque rotary motion from the motorized system moves the drive member to drive the second iaw toward the clamped position. An opposite rotary motion from the motorized system moves the drive member in an opposite direction to release the second jaw and allow the second jaw to move toward the open position.
