1. A method of driving an ultrasonic end effector coupled to an ultrasonic drive system, the method comprising:
driving, by a generator, the ultrasonic end effector at a resonant frequency thereof;
monitoring, by the generator, the resonant frequency of the ultrasonic end effector;
incrementing, by the generator, a timer when the resonant frequency is less than a threshold frequency; and
comparing, by the generator, the timer to a required trigger time.
