NOTES FOR SAFE OPERATION
Read this manual carefully before installation, operation, maintenance, or
inspection of the YRC1000.
In this manual, the Notes for Safe Operation are classified as “DANGER”,
“WARNING”, “CAUTION”, or “NOTICE”.
Even items described as “CAUTION” may result in a serious accident in
some situations.
At any rate, be sure to follow these important items.
DANGER Indicates an imminently hazardous
situation which, if not avoided, will
result in death or serious injury.
Safety Signs identified by the signal
word DANGER should be used
sparingly and only for those
situations presenting the most
serious hazards.
WARNING Indicates a potentially hazardous
situation which, if not avoided, will
result in death or serious injury.
Hazards identified by the signal
word WARNING present a lesser
degree of risk of injury or death than
those identified by the signal word
DANGER.
CAUTION
Indicates a hazardous situation,
which if not avoided, could result in
minor or moderate injury. It may
also be used without the safety alert
symbol as an alternative to
“NOTICE”.
NOTICE NOTICE is the preferred signal word
to address practices not related to
personal injury. The safety alert
symbol should not be used with this
signal word. As an alternative to
“NOTICE”, the word “CAUTION”
without the safety alert symbol may
be used to indicate a message not
related to personal injury.
NOTE To ensure safe and efficient operation at all times, be sure
to follow all instructions, even if not designated as “DAN-
GER”, “WARNING” and “CAUTION".

DANGER
• Before operating the manipulator, make sure the servo power is
turned OFF by performing the following operations. When the servo
power is turned OFF, the SERVO ON LED on the programming
pendant is turned OFF.
– Press the emergency stop buttons on the front door of the
YRC1000, on the programming pendant, on the external control
device, etc.
– Disconnect the safety plug of the safety fence.
(when in the play mode or in the remote mode)
If operation of the manipulator cannot be stopped in an emergency,
personal injury and/or equipment damage may result.
Fig. : Emergency Stop Button
• Before releasing the emergency stop, make sure to remove the
obstacle or error caused the emergency stop, if any, and then turn
the servo power ON.
Failure to observe this instruction may cause unintended movement of
the manipulator, which may result in personal injury.
Fig. : Release of Emergency Stop
TURN
• Observe the following precautions when performing a teaching
operation within the manipulator's operating range:
– Be sure to perform lockout by putting a lockout device on the
safety fence when going into the area enclosed by the safety
fence. In addition, the operator of the teaching operation must
display the sign that the operation is being performed so that no
other person closes the safety fence.
– View the manipulator from the front whenever possible.
– Always follow the predetermined operating procedure.
– Always keep in mind emergency response measures against the
manipulator’s unexpected movement toward a person.
– Ensure a safe place to retreat in case of emergency.
Failure to observe this instruction may cause improper or unintended
movement of the manipulator, which may result in personal injury.
• Confirm that no person is present in the manipulator's operating
range and that the operator is in a safe location before:
– Turning ON the YRC1000 power
– Moving the manipulator by using the programming pendant
– Running the system in the check mode
– Performing automatic operations
Personal injury may result if a person enters the manipulator's
operating range during operation. Immediately press an emergency
stop button whenever there is a problem. The emergency stop buttons
are located on the front panel of the YRC1000 and on the right of the
programming pendant.
• Read and understand the Explanation of the Warning Labels before
operating the manipulator.

Definition of Terms Used Often in This Manual
The MOTOMAN is the YASKAWA industrial robot product.
The MOTOMAN usually consists of the manipulator, the controller, the
programming pendant, and supply cables.
In this manual, the equipment is designated as follows.
WARNING
• Perform the following inspection procedures prior to conducting
manipulator teaching. If there is any problem, immediately take
necessary steps to solve it, such as maintenance and repair.
– Check for a problem in manipulator movement.
– Check for damage to insulation and sheathing of external wires.
• Always return the programming pendant to the hook on the
YRC1000 cabinet after use.
If the programming pendant is left unattended on the manipulator, on a
fixture, or on the floor, etc., the Enable Switch may be activated due to
surface irregularities of where it is left, and the servo power may be
turned ON. In addition, in case the operation of the manipulator starts,
the manipulator or the tool may hit the programming pendant left
unattended, which may result in personal injury and/or equipment
damage.

1 Outline of Arc Welding Diagnosis Function
1.1 Function Outline
This function diagnoses if the welding bead is normal or abnormal based
on the data such as welding current waveforms or welding voltage
waveforms. Notifying the error welding position can prevent a defective
product flowing to the post process, or can indicate the place to adjust at
the adjusting process.
Score mode
Score mode will comprehensively diagnose if the welding bead is normal
or abnormal based on the data from welding current waveforms or welding
voltage waveforms.
Current out-of-range mode
Current out-of range will diagnose if the welding bead is normal or
abnormal based on the differences between the welding current command
value and the effective value.
NOTE The arc welding diagnosis function is not a function to
ensure product quality.
NOTE
The arc welding diagnosis function will determine if the
welding bead is normal or abnormal based on the data such
as welding current waveforms. A normal or abnormal diag-
nosis may be unable to be determined depending on weld-
ing conditions or usage environment. In addition, if tack
welding or welding time is short (less than 2 seconds),
diagnosis will not be possible because the variation in
scores will increase. It can not be used together with
COMARC.
