A method includes a) operating an inertial sensor device arranged on or in a mobile motor-driven processing device in a motion-monitoring operating mode to monitor whether an inertial variable or a variable based on the inertial variable fulfills a motion criterion, wherein the motion criterion is characteristic of a motion of the processing device, b) if the motion criterion is fulfilled, operating the inertial sensor device in a shock and/or impact-monitoring operating mode to monitor whether the inertial variable or a variable based on the inertial variable fulfills a shock and/or impact criterion, wherein the shock and/or impact criterion is characteristic of an atypical motion of the processing device, and c) if the shock and/or impact criterion is fulfilled, transmitting an information signal via the inertial sensor device and operating the control device as a function of the transmitted information signal.

A method is provided for type-specific operating of an electric drive unit, wherein the drive unit is configured for coupling and driving a tool unit selected from a set of different types of tool units. The set includes at least one rotatory tool unit and at least one non-rotatory tool unit. The method includes: driving of a coupled tool unit by the drive unit; identifying operating data of the drive unit during the driving procedure; determining, based on the identified operating data, whether the coupled tool unit is a rotatory tool unit or a non-rotatory tool unit; and controlling the drive unit in a rotation control mode if the coupled tool unit is determined to be a rotatory tool unit, or in a non-rotation control mode if the coupled tool unit is determined to be a non-rotatory tool unit.

Method for type-specific operating of an electric drive unit and system

The invention is directed to a method for braking an electric drive motor having a stator and a rotor. The stator has field coils which have electrical phase connections for three motor phases. To generate an electromagnetic rotating field driving the rotor, the phase connections are connected to a supply voltage via switches actuated by a control unit which closes the switches depending on the rotary position of the rotor. To brake a rotating rotor, a braking current is generated by short-circuiting the phase connections. A phase short circuit is switched in between each two phase connections of the field coils with a preset temporal sequence to brake the rotor. The phase connections short-circuited are each selected corresponding to the rotary position of the rotor so that that field coil is short circuited in which the voltage induced by the magnetic field of the rotating rotor passes through its maximum.
