1. A fastening system for driving a fastener in a workpiece, comprising:
a housing defining a chamber;
a motor positioned within the chamber and having a rotor, the rotor being connectable to the fastener and being operable to
drive the fastener in the workpiece;
a sensor coupled to the rotor to provide a feedback signal representative of a motor operation; and
a controller to receive the feedback signal, to determine a fastener condition based upon the feedback signal, and to oscillate
the rotor between a first position and a second position to vibrate the housing when the fastener condition is different than
a predetermined fastener condition.
