Abstract

A motor-driven surgical cutting and fastening instrument that comprises an end effector, an electric motor, and a motor control circuit. The motor control circuit is for monitoring a parameter of the electric motor that is indicative of movement of a moveable member of the end effector, and for adjustably controlling the electric motor based on the monitored parameter to thereby adjustably control movement of the moveable member of the end effector during forward rotation of the electric motor.
