A surgical instrument includes a motor operably coupled to a firing member, wherein the motor is configured to generate at least one rotational motion to motivate the firing member to cause staples to be deployed during a firing stroke. The surgical instrument includes a primary processor configured to determine a first acceleration of the firing member during the firing stroke, and compare the first acceleration to predetermined threshold acceleration. The surgical instrument also includes a secondary processor configured to determine a second acceleration of the firing member during the firing stroke, and compare the second acceleration to the predetermined threshold value.
