ABSTRACT:
A method for transmitting a permission signal for the operation of a robot is provided. In order to detect whether a permission signal gets from a manual programming unit to a robot control without disturbance, the permission signal is modulated with an auxiliary signal, whose continuous presence at the location of the robot control is monitored. If the auxiliary signal is present, the permission signals are accepted. If the auxiliary signal is no longer present, an EMERGENCY-OFF is triggered. For reasons of safety, the condition of the signal flow is also a two-channel one.
