ABSTRACT:
In each drive direction of a degree of freedom, or in each of the drive directions of several degrees of freedom, the industrial robot is provided with an absolute measured value transmitter or transducer and a relative measured value transmitter which give the instantaneous position of the drives. Should the signal put out by the absolute measured value transmitter not fall within a preselected range of a first window circuit, the robot will be switched off via the control because the robot is moving in a unpermitted working region. The reference position can be chosen with the aid of a second window circuit whose window lies within the range of the first window circuit.
