1. A surgical instrument comprising:

  • an end effector movable between a clamped configuration and an unclamped configuration, the end effector configured to receive a cartridge;

    a displacement member movable between a first position and a second position;

    an encoder configured to detect a position of the displacement member and provide a signal indicative thereof;

    a counting circuit configured to determine an elapsed time and provide a signal indicative thereof; and

    a control circuit coupled to the encoder and counting circuit, the control circuit configured to;

    determine a velocity of the displacement member based on the signal provided by the encoder and the signal provided by the counting circuit; and

    at zero velocity of the displacement member;

    determine a configuration of the end effector, and in the clamped configuration of the end effector;

    determine whether a position of the displacement member is within a first zone or a second zone relative to a threshold position;

    in the first zone, provide a first alert indicating that the surgical instrument is stalled; and

    in the second zone, provide a second alert indicating that the cartridge is not present within the end effector.
