Function
Real time monitoring of conditions
such that the stopping time limit will
not be exceeded. Robot speed is
limited to ensure that the stop time
limit is not exceeded. The control SW
continuously calculates the stopping

limit, the speed of motion is reduced to
ensure the limit is not exceeded. The
safety function performs the same
