1. A method for operating a coordinate measuring machine having a coordinate measuring device movable in at least one direction and driven by at least one electric motor, which comprises the steps of:

  • a) measuring an electrical drive current flowing through the electric motor to move the electric motor and in this way to move the coordinate measuring device;

    b) determining one of a limit value and a limit value range defined by a lower limit value and an upper limit value for the electrical drive current in dependence on at least one of a set speed and a set acceleration at which one of a movement of the electric motor and a movement of the coordinate measuring device is intended to take place, and a functional relationship is fixedly predetermined between at least one of the set speed and the set acceleration on the one hand and a current limit value on the other hand; and

    c) bringing the coordinate measuring device to a predefined state if one of the electrical drive current reaches the limit value, the electrical drive current exceeds the limit value, and the limit value range is departed from.
