1.1.5. Definition of Safety Functions
Emergency Stop Function- IEC 204-1,10,7
There is one emergency stop button on the controller and another on the teach pendant.
If necessary, additional emergency buttons can be connected to the robot's safety
chain circuit. The emergency stop function, which overrides all other robot controls,
removes drive power from robot axis actuators, stop all moving parts and disconnect
power in order not to use other dangerous functions controlled by the robot.
Safety Stop Function-ISO 10218(EN 775), 6.4.3
When a safety stop circuit is provided, each robot must be delivered with the
necessary connections for the safeguards and interlocks associated with this circuit.
The robot has a number of electrical inputs which can be used to connect external
safety equipment, such as safety gates and light curtains. This allows the robot's
safety functions to be activated both by peripheral equipment and by the robot itself.
Speed Limitation Function-ISO 10218(EN 775), 3.2.17
In manual mode, the speed of robot is strictly limited to 250 mm per second as a
maximum. The speed limitation applies not only to the TCP(Tool Center Point), but
to all parts of robot. The speed of equipment mounted on the robot can be monitored.
Working Envelope Restriction- ANSI/RIA R15.06-1999
The working envelop of each robot axes can be restricted using software limits. Axis
1,2,3 can also be restricted by means of mechanical stops.
Operation Mode Selection- ANSI/RIA R15.06-1999
The robot can be operated either manually or automatically. In manual mode, the robot
can be operated by using the teach pendant only, i. e. not by any external equipment.
(1) Install Safety Fence away from the working space of robot in order to prevent
from any possible collision and interface between workers and robot during the robot
operation.
Any accidents can be take place when any workers or any other persons enter inside
the safety fence without protective actions. Safety fence shall be equipped with the
emergency stop mechanism that can activate emergency stop of robot if any workers
would get into the safety fence for examination of robot and welding equipment and
replacement of tip dresser and tip etc. during robot operation.
(2) Safety Fence shall fully cover the working space of robot and be installed to
secure the enough space in order to evade any interference with robot during
teaching and repair operation of workers within the safety fence. And it shall be

interlock panel, timer etc. Any loose or protruded cables and/or wires can cause
workers' slippery or disconnection of cable by fork lift.
(6) Locate robot manipulator, controller and operation stand where workers can
!
clearly see the movement of robot manipulator. When operator do not acknowledge
abnormal situation of robot or other workers' working at the robot due to the
invisible situation, operator's robot operation can cause a large accident.
(7) Limit the workable space of robot by utilizing soft limit or mechanical stopper
etc. when the required work space of robot is smaller than the workable space of
robot. In case of abnormal operation, any excessive working out of the workable
space can be stopped previously. (Please refer to Operation and Manipulator
Maintenance Manual)
(8) Install safety curtain or cover for spatters made during welding work which can
cause personal injury or fire accident. In any case, safety curtain or cover shall
be installed to allow operator to clearly see the movement of robot manipulator.
(9) Automatic operation and manual operation which mean the actual operation state
of robot shall be notified to workers even in the distance by easily visible light
or device. Install buzzer or alarming light for sign of starting automatic operation
of robot.
(10) Remove any protrusions, sharp edges at equipments, devices around the robot which
can cause personal injury or any other accidents.
(11) Input and output of workpiece by inserting worker's hands inside safety fence
shall be strictly prohibited due to the risks of pressure or cutting injury
accident.
1. Safety, Operation Panel, Teach Pendant (1) Safety

studied for the optimized performance and functionality of the robot. In case of bad
installation situation of robot, the serious problems can take place as follows;
- Error of relative position between robot and workpiece during operation.
- Bad performance quality of robot caused by vibration.
- Shortening lifetime of robot
- Cause of serious accidents
The following lists the safety precautions to which careful consideration must be
made by operator, worker or installation persons.
General Safety Precautions
(1) Design and install the robot system in completely compliance with laws,
regulations and safety requirements being valid in the country where the robot
system is installed.
(2) All the workers for the robot system must have the good knowledge on the
information specified in the operation and maintenance manual and also have a good
command of operation and maintenance of the robot.
(3) Installation workers of robot must follow the safety requirements when they face
any safety problems in installation.
(4) System Supplier must ensure that all the circuits utilizing safety function
perfectly perform their functionalities in a safe way.
(5) Install primary power supply which can be disconnected from the place outside
the operation area of the robot.
(6) System supplier must ensure that all the circuits utilizing emergency stop
function perform their functionalities in a safe way.
(7) For immediate emergency stop, install emergency stop button within operator's
easily accessible distance.
Technical Safety Precautions
(1) Remove any interference problems with peripheral equipments considering
dimension and operating space of the robot.
(2) Evade the installation of robot at the places where have direct ray of sun, many
oil, chemical material, explosives, metal powder or humid and wet atmosphere.
(3) Install at the place where ambient temperature is 0∼ 45℃.
(4) Secure sufficient space for facilitation of disassembly and examination of the
robot.
(5) Install safety fence with a gate so that no worker can enter into the operating
range of robot without permission.
(6) Remove any obstacles out of operating space of robot.
(7) Take the special measure considering heat dynamics in case of installation of
robot at the places where have direct ray of sun or near heating equipment.
(8) Take the special measure in case of installation of robot at the place where there
are a lot of dusty metal powder, chemical dusts in the air.
(9) Install robot not to receive any short circuit from welding gun and equipment.
(Insulate robot arm between spot sun completely)
(10) Grounding is very important for preventing from abnormal operation or electric
shock caused by noise. Observe the following installation method.
- Install exclusive grounding terminal using class 3 or higher grounding
method.(In case of input voltage of 400V or higher, observe special class 3
or higher grounding method.)
1. Safety, Operation Panel, Teach Pendant (1) Safety
- Connect Grounding line into the grounding bus-bar inside the controller.
- In case of direct grounding of the robot by anchoring at floor, two point
grounding both by robot manipulator and by controller can produce closed circuit
and further cause abnormal operation of the robot on the contrary. In this
case, connect the grounding line to the base of robot manipulator and disconnect
to the controller. When robot trembles during stopping operation, check and
examine the grounding status immediately since the possible main causes are
incomplete grounding or closed circuit.
- In using built-in transformer gun, primary power cable can be easily worn out
by directly contacting with the gun. In this case, connect the grounding line
to the base of robot directly and disconnect to controller in order to protect
controller and preventing from any electric shock.
Install robot manipulator, controller, other peripheral equipment. Be sure that
there are sufficient rooms for maintenance on the manipulator, controller and other
peripheral equipment. Install robot manipulator and controller as per the guideline
as described in the figure below.

Safety working procedures must be observed to prevent from any accidents. Safety
device or circuit shall not be modified and disregarded by workers or operators at
any time.
Be careful of any possible accidents caused by electric shock. All normal operations
in automatic mode must be executed outside safety fence. Prior to operation, be sure
there are no personnel within the manipulator's working envelope.
1.1.7.1. Safety measure for robot operation
!
(1) Have the robot system operators, any workers who is possible to operate or any
superintendents attend the training courses held by Hyundai in order that they can
have a good command of safety and robot functions. Do not allow workers who do not
attend the training courses to operate the robot.
(2) Wear safety helmet, safety glass, safety boots during operation.
(3) 2 workers as a team must work together. One worker must supervise through operation
panel while another worker make teaching operation. One worker always must be in
a position to push emergency stop button while another worker execute operation
work inside or outside the operation space of the robot with sufficient cautions.
Furthermore, all the workers must have a good knowledge on escaping route before
their operation work.
(4) Supply power-on after certainly ensuring that there is no persons within operating
space of the robot.
(5) Do teaching work outside the working envelope of the robot, in principle. However,
after motor-off, you may execute work within the working envelope of the robot by
hand-carrying key switch or safety plug, which will prevent from automatic
operation which can be made by any third parties. Furthermore, pay your special
attention to direction of movements which can be made by abnormal or error situation,
if any.
1. Safety, Operation Panel, Teach Pendant (1) Safety
first the stop status of the robot and further investigate the cause to execute
relevant measure.
- When the emergency stop function does not work, disconnect the power supply
immediately and further investigate the cause to execute relevant measure.
- No one who have no operation and maintenance training provided by Hyundai can be
authorized to do the investigation of the cause for abnormal situations. In the
event of emergency stop, re-start of motor must be made by the defined procedure
only after implementing the measure as a result of the detailed investigation
to the cause for abnormal operation.
(15) Prepare relevant working manual on robot operation, working method and the
required action for abnormal situations according to the installation places and
working contents. Proceed with any works as per the relevant working manual.
(16) Precautions during the stop of robot
Do not access to the robot even though the robot is just stopping. There can be
a serious accident caused by sudden movement of robot when you access to the stopped

Always, pay your careful attention to the unexpected movement of the robot even
though it is the above situation which you can enter to working envelope. Entering
to the working envelope of the robot without any preparation for unexpected
emergency situation must be prohibited at any time.
Note) As specified in the above table, in case of temporary stopping,
access to the working envelope of the robot is not allowed. However,
when you try to get inside the working envelope of the robot in order
to make corrections for minor problems such as nozzle contact and arc
trouble, enter the working envelope of robot only after following the
same method as you enter the working envelope for teaching work.
(17) When you finish the operation work of robot, do cleaning work for the area inside
the safety fence to remove any tools, oil or foreign material which left on the
floor. Contamination of working area by oil and any left tools can cause slippery
and personal injury. Please do your cleaning and proper arrangement regularly,
1.1.7.2 Safety Measure for Robot Try-out
!
Engineering error, Teaching error and manufacturing defects on the total system
including teaching program, jig and sequence etc. can be found during try-out of the
robot. Therefore, do your try-out operation taking your due consideration into the
safety matter. Safety related accident can took place due to the combined reasons.
(1) Check first the functions of signals and buttons such as emergency stop button
and stop button etc. before robot operation and further check error detection
function. Checking of all the signals for stopping the robot is the most important
thing. When you can foresee the possible accident previously, the most important
thing is to stop the robot.
(2) For the try-out of robot, operate in the lower speed of 20%∼30% and further check
movement more than 1 cycle repeatedly. When you find any problems, modify them
immediately. Afterwards, make speed-up by the order of first 50%, second 75% and
final 100% and further check movement more than 1 cycle for each speed set-up
respectively. When you make speed set-up of high speed at the beginning, the
unexpected accident can take place.
(3) You can not foresee any problems to be made during try-out. Do not enter inside
