Abstract
In a method for operating a coordinate measuring machine and to a coordinate measuring machine, a coordinate measuring device, of the coordinate measuring machine is moved in at least one direction while being driven by an electric motor. An electrical drive current which flows through the electric motor for moving the electric motor and, move the coordinate measuring device is measured. A limit value for the electrical drive current is determined on the basis of a desired speed and/or on the basis of a desired acceleration with which the electric motor or the coordinate measuring device is intended to move. If the electrical drive current reaches the limit value determined and/or if the electrical drive current exceeds the limit value determined, the coordinate measuring device is changed to a predefined state, by virtue of the computer or the microcontroller switching off one of the switches disposed in the current path.
