1. A method of operating a surgical instrument, the method comprising:
driving a displacement driver a first distance with a motor;
measuring a time period required to drive the displacement driver the first distance;
presenting an indicia on a display indicative of a velocity mode for the displacement driver;
receiving a user input corresponding to the velocity mode; and
setting a velocity of the motor based on the user input.
