Abstract: A power tool includes a housing, a motor positioned within the housing, an output shaft driven by the motor, the output shaft configured to be coupled to an accessory for operation thereof, a sensing circuit configured to detect, during operation of the power tool, an operating characteristic of the motor, and a controller. The controller is configured to receive a signal from the sensing circuit representing the operating characteristic of the motor, compare the operating characteristic of the motor to a first predetermined threshold, and in response to the operating characteristic exceeding the predetermined threshold, perform a loss of control check on the power tool. Performing the loss of control check includes comparing a detected motion of the power tool to a second predetermined threshold, and tripping loss of control functionality based on whether the detected motion of the power tool exceeds the second predetermined threshold.
