1. A surgical stapling system, comprising:
a motor;
a drive assembly comprising a drive train coupled to the motor to actuate a function of a surgical end effector, wherein the drive train is actuatable by the motor through a drive stroke; and
a control circuit coupled to the drive assembly, wherein the control circuit is configured to:
monitor a first parameter of the drive assembly during the drive stroke;
determine a stored kinetic energy of the drive assembly based on the first parameter;
monitor a second parameter of the drive assembly during the drive stroke, wherein the first parameter and the second parameter are different;
compare the monitored second parameter to a parameter threshold indicative of a motor stall condition;
determine a motor setting of the motor based on the determined stored kinetic energy and the comparison of the monitored second parameter to the parameter threshold.
