1. A method for detecting drive train failures in a surgical instrument, the method comprising:
generating, by an electric motor, a mechanical output to motivate a drivetrain to transmit a motion to a jaw assembly of the surgical instrument;
activating, by a control circuit, a safe mode in response to an acute failure of the drivetrain; and
activating, by the control circuit, a bailout mode in response to a catastrophic failure of the drivetrain.
