1. A method of operating a robotically controlled surgical instrument that includes an end effector, a motor, and a driving assembly, the method comprising:
(a) distally advancing the driving assembly within the end effector;
(b) measuring at least a temperature of the motor;
(c) making a first determination that the measured temperature of the motor exceeds a first temperature threshold;
(d) in response to making the first determination, reducing or stopping power to the motor;
(e) distally advancing the driving assembly within the end effector after reducing or stopping power to the motor;
(f) making a second determination that the measured temperature of the motor exceeds a second temperature threshold; and
(g) in response to making the second determination, reducing or stopping power to the motor; and
(h) after reducing or stopping power to the motor, making a third determination that the measured temperature of the motor exceeds a third temperature threshold, wherein the third temperature threshold is different than the first and second temperature thresholds.
