1. A powered stapling device, comprising:
a circular stapling head assembly;
an anvil;
a trocar coupled to the anvil and coupled to a motor, wherein the motor is configured to advance and retract the trocar; and
a control circuit coupled to the motor, wherein the control circuit is configured to:
determine a position of the trocar in one of a plurality of zones;
set an anvil closure rate based on the determined position of the trocar;
determine a trocar closure rate;
determine the anvil closure rate;
compare the trocar closure rate to the anvil closure rate to determine a difference between the trocar closure rate and the anvil closure rate; and
for the difference being greater than a predetermined value, extend and retract the trocar to reset the anvil.
