4. Definitions of safety functions
4.1 Emergency stop, IEC 204-1,10.7:
A condition which overrides all other robot controls, removes drive power from robot axis
actuators, and initiates the stopping of all moving parts, and removes power from other
dangerous functions controlled by the robot.
4.2 Enabling device, ISO 11161,3.4:
A manually operated device which, when continuously activated in one position only,
allows hazardous functions but does not initiate them. In any other position, hazardous
functions are stopped safely.
4.3 Safety stop, ISO 10218,6.4.3:
The safely stop is to have provisions to connect safeguards and interlocks to this circuit.
It must be necessary to reset the power before any robot motion can be initiated.
Resetting of the power by the safety stop itself must not initiate any motion.
4.4 Reduced speed, ISO 10218,3.2.17:
A single selectable velocity defined by the robot manufacturer which automatically
restricts robot velocity so as to allow sufficient time for persons either to get clear of
hazardous robot movements or stop the robot.
4.5 Safe interlocking, ISO 10218,3.2.8:
An arrangement that interconnects safeguard(s) or similar device(s) with the robot
control system and/or power system of the robot and its associated equipment.
4.6 Hold-to-run control, ISO10218, 3.2.7:
A control which allows movements only during manual actuation of that control and
which causes these movements to stop as soon as it is released.
