A motorized surgical instrument is disclosed. The surgical instrument includes a displacement member, a motor coupled to the displacement member, the motor operable to translate the displacement member, a control circuit coupled to the motor, and a position sensor coupled to the control circuit. The control circuit is configured to receive a position output of the position sensor indicative of at least one position of the displacement member and control velocity of the motor to translate the displacement member at a plurality of velocities corresponding to the position output. Each of the plurality of velocities is maintained in a predetermined zone.
