Abstract
A power tool that includes a motor coupled to a drive mechanism, and a removable and rechargeable battery pack coupled to the motor to selectively provide power signals to the motor. The power tool also includes a controller configured to monitor a plurality of conditions of the power tool, such as battery pack voltage, battery pack temperature, operational current, and the like. The controller is also configured to detect one or more events related to the plurality of conditions of the power tool. If the operational current of the power tool exceeds a first threshold value, a power signal duty cycle is reduced from a first duty cycle value to a second duty cycle value to limit the amount of torque the power tool is able to generate.
