Abstract: A method for setting at least one parameter of a handheld power tool includes recording at least one first characteristic variable using at least one internal sensor unit or an external sensor unit and transmitting the first characteristic variable to at least one of (i) an internal data processing unit and (ii) an external data processing unit. The method further includes processing the first characteristic variable into at least one of (i) at least one first parameter output and (ii) an output of a combination of parameters and transmitting using a communication unit to at least one of (i) an internal open-loop and (ii) a closed-loop control unit. The method further includes calculating from the first parameter output at least one operating parameter of the handheld power tool and setting it on the handheld power tool.

Abstract: A method for limiting a power consumption in the event of overload of an electrical drive, in particular an electric motor of a handheld power tool, by outputting power to the electrical drive and controlling the voltage of the electric motor using at least one circuit breaker. At least the control signal and therefore the power consumption of the electric motor are adapted if an overload torque and/or the power consumption is/are exceeded such that the handheld power tool is operated in a protective mode with a defined, reduced power. At least the control signal for the voltage of the electric motor and therefore the power consumption of the electric motor are reduced in the protective mode with reduced power in an interval of time that is greater than an integer multiple of half the period time of the mains frequency if the overload torque is not reduced.
