A surgical instrument is disclosed. The surgical instrument comprises an end effector comprising an ultrasonic blade and a clamp arm. The clamp arm is movable relative to the ultrasonic blade to transition the end effector between an open configuration and a closed configuration to clamp tissue between the ultrasonic blade and the clamp arm. The surgical instrument further comprises a transducer configured to generate an ultrasonic energy output and a waveguide configured to transmit the ultrasonic energy output to the ultrasonic blade. The surgical instrument further comprises a control circuit configured to monitor a parameter of the surgical instrument, wherein crossing an upper predetermined threshold of the parameter causes the control circuit to effect a first electromechanical system, and wherein crossing a lower predetermined threshold of the parameter causes the control circuit to effect a second electromechanical system different than the first electromechanically system.
