Abstract

A surgical stapling instrument for use with a staple cartridge including a sled and staples is disclosed. The surgical stapling instrument comprises a firing system. The firing system comprising a motor and a driving member operably coupled to the motor. The motor is configured to cause the driving member to advance the sled to deploy the staples into tissue grasped by the surgical stapling instrument. The driving member is movable by the motor along a predefined firing path. The surgical stapling instrument further comprises a control circuit that is configured to detect a location of the sled along the firing path, and adjust a motor control program based on the location of the sled.
