Abstract

A surgical instrument includes a drive member movable by a drive motor between a home position and an end of stroke. A mechanical stop is disposed at or near the end of stroke and is structured to increase resistance to movement of the drive member from a first position to a second position. A control system detects a current spike associated with the increased resistance and interrupts power to the drive motor.
