1. A surgical instrument, comprising:
a housing comprising a motor;
an elongate shaft;
an end-effector, comprising:
a first jaw;
a second jaw movable relative to said first jaw;
an anvil; and
a staple cartridge, comprising:
a plurality of staples;
a plurality of driver elements; and
a sled configured to eject said staples toward said anvil, wherein said sled is movable between a proximal unfired position and a distal fired position through a firing stroke;
a cutting member, wherein said cutting member is configured to be advanced distally into said sled by said motor; and
a control circuit configured to:
detect the location of said cutting member;
monitor a parameter indicative of a load experienced by said cutting member;
determine a threshold value of the parameter based on a portion of said firing stroke; and
adjust operation of said motor if the monitored parameter exceeds the determined threshold value.
