摘要：A system and method for precision fastening of a fastener. The fasteningsystem includes a motor and a sensor that provides a feedback signal from the motor toa controller. The controller compares the feedback signal to a threshold value todetermine if an error condition exists. If the error condition exists, the controller
oscillates a rotor to the motor between a first and a second position. In one construction,a resolver provides a signal to the controller representing a position of the oscillatingrotor. The oscillating rotor vibrates the housing, thereby alerting an operator of theerror condition. In one construction, the fastener device can alert the operator that thefastener is not tightened to a proper torque, and that the fastener is not rotatedthrough a proper angle of rotation.
