Brake test function with an external prompt

The safety control system may be provoked externally into sending a prompt to the motion
controller regarding the brake test. This external prompt to perform the brake test may be
necessary if the industrial robot is part of a production line, for example. The production line
is generally controlled by a higher level controller.

The system or plant integrator is tasked with planning the external prompt for the manual

brake test (see

Planning the prompt for the manual brake test [

The external prompt for the brake test initiates the following procedure:

Prompt for brake test

Prompt recognised
