Task
Note
(2) Wiring the cables
z
Use IAI’s genuine cables to connect the actuator and controller or connect a teaching
tool, etc.
z
Do not damage, forcibly bend, pull, loop round an object or pinch the cables or place
heavy articles on top. Current leak or poor electrical continuity may occur, resulting in
fire, electric shock or malfunction.
z
Wire the product correctly after turning off the power.
z
When wiring a DC power supply (+24 V), pay attention to the positive and negative
polarities.
Connecting the wires in wrong polarities may result in fire, product failure or
malfunction.
z
Securely connect the cables and connectors so that they will not be disconnected or
come loose. Failing to do so may result in fire, electric shock or product malfunction.
z
Do not cut and reconnect the cables of the product to extend or shorten the cables.
Doing so may result in fire or product malfunction.
(3) Grounding
z
Be sure to provide class D (former class 3) grounding for the controller. Grounding is
required to prevent electric shock and electrostatic charges, improve noise resistance
and suppress unnecessary electromagnetic radiation.
4 Installation/
startup
(4) Safety measures
z
Implement safety measures (such as installing safety fences, etc.) to prevent entry
into the movement range of the robot when the product is moving or can be moved.
Contacting the moving robot may result in death or serious injury.
z
Be sure to provide an emergency stop circuit so that the product can be stopped
immediately in case of emergency during operation.
z
Implement safety measures so that the product cannot be started only by turning on
the power. If the product starts suddenly, injury or product damage may result.
z
Implement safety measures so that the product will not start upon cancellation of an
emergency stop or recovery of power following a power outage. Failure to do so may
result in injury, equipment damage, etc.
z
Put up a sign saying “WORK IN PROGRESS. DO NOT TURN ON POWER,” etc.,
during installation, adjustment, etc. If the power is accidently turned on, electric shock
or injury may result.
z
Implement measures to prevent the work part, etc., from dropping due to a power
outage or emergency stop.
z
Ensure safety by wearing protective gloves, protective goggles and/or safety shoes,
as necessary.
z
Do not insert fingers and objects into openings in the product. Doing so may result in
injury, electric shock, product damage, fire, etc.
z
When releasing the brake of the vertically installed actuator, be careful not to let the
actuator drop due to its dead weight, causing pinched hands or damaged work part,
etc.
5 Teaching
z
Whenever possible, perform teaching from outside the safety fences. If teaching must
be performed inside the safety fences, prepare “work rules” and make sure the
operator understands the procedures thoroughly.
z
When working inside the safety fences, the operator should carry a handy emergency
stop switch so that the operation can be stopped any time when an abnormality
occurs.
z
When working inside the safety fences, appoint a safety watcher in addition to the
operator so that the operation can be stopped any time when an abnormality occurs.
The safety watcher must also make sure the switches are not operated inadvertently
by a third party.
z
Put up a sign saying “WORK IN PROGRESS” in a conspicuous location.
No.
Operation
Description
Description
6
Trial Operation Ɣ When the work is carried out with 2 or more persons, make it clear who is
to be the leader and who to be the follower(s) and communicate well with
each other to ensure the safety of the workers.
Ɣ After the teaching or programming operation, perform the check operation
one step by one step and then shift to the automatic operation.
Ɣ When the check operation is to be performed inside the safety protection
fence, perform the check operation using the previously specified work
procedure like the teaching operation.
Ɣ Make sure to perform the programmed operation check at the safety
speed. Failure to do so may result in an accident due to unexpected
motion caused by a program error, etc.
Ɣ Do not touch the terminal block or any of the various setting switches in
the power ON mode. Failure to do so may result in an electric shock or
malfunction.
7
Automatic
Operation
Ɣ Check before starting the automatic operation or rebooting after operation
stop that there is nobody in the safety protection fence.
Ɣ Before starting automatic operation, make sure that all peripheral
equipment is in an automatic-operation-ready state and there is no alarm
indication.
Ɣ Make sure to operate automatic operation start from outside of the safety
protection fence.
Ɣ In the case that there is any abnormal heating, smoke, offensive smell, or
abnormal noise in the product, immediately stop the machine and turn
OFF the power switch. Failure to do so may result in a fire or damage to
the product.
Ɣ When a power failure occurs, turn OFF the power switch. Failure to do so
may cause an injury or damage to the product, due to a sudden motion of
the product in the recovery operation from the power failure.
