1.7.2. Safety Precautions for Operating Test
In case of operating test, errors in design or teaching and inferiority in manufacturing
are possibly seen in the entire system such as teaching program, jig, and sequence.
Thus, be more careful and safe in case of operating test. Accidents may occur by
these combined causes.
(1) Before handling, check the stop buttons and signal functions to stop the robot
such as emergency stop button or stop button. And then, check the
abnormality - detective movements. Above all, it is the most critical to check
all the stop signals. It would be the most important to stop the robot when any
possible accidents are predicted.
(2) In case of operating test, start the robot at low speed(approximately
20%~30%) in the variable speed function, and repeat it more than one cycle
to check the movements. If any errors are found, immediately correct them.
After then, increase in speed (50% → 75% → 100%) gradually, and repeat
more than one cycle respectively to check the movements. Operating at high
speed from the very beginning may cause a serious accident.
(3) In case of operating test, it is hard to predict what problems would happen.
Do not enter the safety fence during operating test. Unexpected accidents are
likely to occur because of its low reliability.
