Abstract
A motorized surgical instrument is disclosed. The surgical instrument includes a displacement member, a motor coupled to displacement member, a control circuit coupled to the motor, a parameter sensor coupled to the control circuit and a position sensor coupled to the control circuit. The control circuit is configured to receive a parameter output of the parameter sensor indicative of a force applied to translate the displacement member, determine a duration during which the parameter output is maintained at or above a predetermined fault threshold, receive a position output of the position sensor indicative of at least one position of the displacement member during the duration, and effect a motor control action based on the duration and the at least one position.
