1. A method of operating a surgical instrument, the surgical instrument comprising an electric motor coupled to an end effector, a motor controller coupled to the motor, a parameter threshold detection module, a sensing module, a processor, and a memory coupled to the processor, the memory storing executable instructions that when executed by the processor cause the processor to execute the method, the method comprising:
monitoring multiple parameter thresholds by the parameter threshold detection module;
sensing tissue compression by the sensing module;
monitoring multiple levels of action thresholds by the processor;
monitoring speed of the motor by the processor;
incrementing a drive unit of the motor by the processor;
sensing tissue compression by the processor; and
providing rate and control feedback by the processor to a user of the surgical instrument.
