Abstract

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.
