ROBOT ARM SETUP & MAINTENANCE
BFP-A3335-J

All teaching work must be carried out by an operator who has received special
training. (This also applies to maintenance work with the power source turned
ON.)
Enforcement of safety training
For teaching work, prepare a work plan related to the methods and procedures
of operating the robot, and to the measures to be taken when an error occurs
or when restarting. Carry out work following this plan. (This also applies to
maintenance work with the power source turned ON.)
Preparation of work plan
Prepare a device that allows operation to be stopped immediately during
teaching work. (This also applies to maintenance work with the power source
turned ON.)
Setting of emergency stop switch
During teaching work, place a sign indicating that teaching work is in progress
on the start switch, etc. (This also applies to maintenance work with the power
source turned ON.)
Indication of teaching work in progress
Provide a fence or enclosure during operation to prevent contact of the
operator and robot.
Installation of safety fence
Establish a set signaling method to the related operators for starting work, and
follow this method.
Signaling of operation start
As a principle turn the power OFF during maintenance work. Place a sign
indicating that maintenance work is in progress on the start switch, etc.
Indication of maintenance work in progress
Before starting work, inspect the robot, emergency stop switch and other
related devices, etc., and confirm that there are no errors.
Inspection before starting work
Always read the following precautions and the separate "Safety
Manual" before starting use of the robot to learn the required
measures to be taken.

The points of the precautions given in the separate "Safety Manual" are given below.
Refer to the actual "Safety Manual" for details.
When automatic operation of the robot is performed using multiple control
devices (GOT, programmable controller, push-button switch), the interlocking of
operation rights of the devices, etc. must be designed by the customer.
Use the robot within the environment given in the specifications. Failure to do
so could lead to a drop or reliability or faults. (Temperature, humidity,
atmosphere, noise environment, etc.)
Transport the robot with the designated transportation posture. Transporting
the robot in a non-designated posture could lead to personal injuries or faults
from dropping.
Always use the robot installed on a secure table. Use in an instable posture
could lead to positional deviation and vibration.
Wire the cable as far away from noise sources as possible. If placed near a noise
source, positional deviation or malfunction could occur.
Do not apply excessive force on the connector or excessively bend the cable.
Failure to observe this could lead to contact defects or wire breakage.
Make sure that the workpiece weight, including the hand, does not exceed the
rated load or tolerable torque. Exceeding these values could lead to alarms or
faults.
Securely install the hand and tool, and securely grasp the workpiece. Failure to
observe this could lead to personal injuries or damage if the object comes off or
flies off during operation.
Securely ground the robot and controller. Failure to observe this could lead to
malfunctioning by noise or to electric shock accidents.
Indicate the operation state during robot operation. Failure to indicate the state
could lead to operators approaching the robot or to incorrect operation.
When carrying out teaching work in the robot's movement range, always secure
the priority right for the robot control. Failure to observe this could lead to
personal injuries or damage if the robot is started with external commands.
Keep the jog speed as low as possible, and always watch the robot. Failure to do
so could lead to interference with the workpiece or peripheral devices.
After editing the program, always confirm the operation with step operation
before starting automatic operation. Failure to do so could lead to interference
with peripheral devices because of programming mistakes, etc.
Make sure that if the safety fence entrance door is opened during automatic
operation, the door is locked or that the robot will automatically stop. Failure to
do so could lead to personal injuries.
Never carry out modifications based on personal judgments, or use non-
designated maintenance parts.
Failure to observe this could lead to faults or failures.

When the robot arm has to be moved by hand from an external area, do not
place hands or fingers in the openings. Failure to observe this could lead to
hands or fingers catching depending on the posture.
Do not stop the robot or apply emergency stop by turning the robot controller's
main power OFF. If the robot controller main power is turned OFF during
automatic operation, the robot accuracy could be adversely affected. Moreover,
it may interfere with the peripheral device by drop or move by inertia of the arm.
Do not turn off the main power to the robot controller while rewriting the
internal information of the robot controller such as the program or parameters.
If the main power to the robot controller is turned off while in automatic
operation or rewriting the program or parameters, the internal information of the
robot controller may be damaged.
Do not connect the Handy GOT when using the GOT direct connection function
of this product. Failure to observe this may result in property damage or bodily
injury because the Handy GOT can automatically operate the robot regardless
of whether the operation rights are enabled or not.
Do not remove the SSCNET III cable while power is supplied to the controller.
Do not look directly at light emitted from the tip of SSCNET III connectors or
SSCNET III cables. Eye discomfort may be felt if exposed to the light.
(Reference: SSCNET III employs a Class 1 or equivalent light source as
specified in JIS C 6802 and IEC60825-1 (domestic standards in Japan).)
Attach the cap to the SSCNET III connector after disconnecting the SSCNET
III cable. If the cap is not attached, dirt or dust may adhere to the connector
pins, resulting in deterioration connector properties, and leading to malfunction.
Make sure there are no mistakes in the wiring. Connecting differently to the way
specified in the manual can result in errors, such as the emergency stop not
being released. In order to prevent errors occurring, please be sure to check
that all functions (such as the teaching box emergency stop, customer emer-
gency stop, and door switch) are working properly after the wiring setup is com-
pleted.
Use the network equipments (personal computer, USB hub, LAN hub, etc)
confirmed by manufacturer. The thing unsuitable for the FA environment
(related with conformity, temperature or noise) exists in the equipments
connected to USB. When using network equipment, measures against the noise,
such as measures against EMI and the addition of the ferrite core, may be
necessary. Please fully confirm the operation by customer. Guarantee and
maintenance of the equipment on the market (usual office automation
equipment) cannot be performed.
To maintain the security (confidentiality, integrity, and availability) of the robot
and the system against unauthorized access, DoS*1 attacks, computer viruses,
and other cyberattacks from unreliable networks and devices via network, take
appropriate measures such as firewalls, virtual private networks (VPNs), and
antivirus solutions.
Mitsubishi Electric shall have no responsibility or liability for any problems
involving robot trouble and system trouble by unauthorized access, DoS
attacks, computer viruses, and other cyberattacks.
*1 DoS: A denial-of-service (DoS) attack disrupts services by overloading sys-
tems or exploiting vulnerabilities, resulting in a denial-of-service (DoS) state.

Safety Precautions 1-4
1.2.1 Precautions given in the separate Safety Manual
The points of the precautions given in the separate "Safety Manual" are given below.
Refer to the actual "Safety Manual" for details.
When automatic operation of the robot is performed using multiple control devices
(GOT, programmable controller, push-button switch), the interlocking of operation
rights of the devices, etc. must be designed by the customer.
Use the robot within the environment given in the specifications. Failure to do so
could lead to a drop or reliability or faults. (Temperature, humidity, atmosphere,
noise environment, etc.)
Transport the robot with the designated transportation posture. Transporting the
robot in a non-designated posture could lead to personal injuries or faults from
dropping.
Always use the robot installed on a secure table. Use in an instable posture could
lead to positional deviation and vibration.
Wire the cable as far away from noise sources as possible. If placed near a noise
source, positional deviation or malfunction could occur.
Do not apply excessive force on the connector or excessively bend the cable.
Failure to observe this could lead to contact defects or wire breakage.
Make sure that the workpiece weight, including the hand, does not exceed the
rated load or tolerable torque. Exceeding these values could lead to alarms or
faults.
Securely install the hand and tool, and securely grasp the workpiece. Failure to
observe this could lead to personal injuries or damage if the object comes off or
flies off during operation.
Securely ground the robot and controller. Failure to observe this could lead to
malfunctioning by noise or to electric shock accidents.
Indicate the operation state during robot operation. Failure to indicate the state
could lead to operators approaching the robot or to incorrect operation.
When carrying out teaching work in the robot's movement range, always secure
the priority right for the robot control. Failure to observe this could lead to personal
injuries or damage if the robot is started with external commands.
Keep the jog speed as low as possible, and always watch the robot. Failure to do
so could lead to interference with the workpiece or peripheral devices.
After editing the program, always confirm the operation with step operation before
starting automatic operation. Failure to do so could lead to interference with
peripheral devices because of programming mistakes, etc.
Make sure that if the safety fence entrance door is opened during automatic oper-
ation, the door is locked or that the robot will automatically stop. Failure to do so
could lead to personal injuries.
Never carry out modifications based on personal judgments, or use non-desig-
nated maintenance parts.
Failure to observe this could lead to faults or failures.
When the robot arm has to be moved by hand from an external area, do not place
hands or fingers in the openings. Failure to observe this could lead to hands or fin-
gers catching depending on the posture.

1-5 Safety Precautions
1Before starting use
Do not stop the robot or apply emergency stop by turning the robot controller's
main power OFF.
If the robot controller main power is turned OFF during automatic operation, the
robot accuracy could be adversely affected.
Do not turn off the main power to the robot controller while rewriting the internal
information of the robot controller such as the program or parameters. If the main
power to the robot controller is turned off while in automatic operation or rewriting
the program or parameters, the internal information of the robot controller may be
damaged.
Do not connect the Handy GOT when using the GOT direct connection function of
this product. Failure to observe this may result in property damage or bodily injury
because the Handy GOT can automatically operate the robot regardless of
whether the operation rights are enabled or not.
Do not connect the Handy GOT to a programmable controller when using an iQ
Platform compatible product with the CR750-Q/CR751-Q/CR760-Q controller. Fail-
ure to observe this may result in property damage or bodily injury because the
Handy GOT can automatically operate the robot regardless of whether the opera-
tion rights are enabled or not.
Do not remove the SSCNET III cable while power is supplied to the multiple CPU
system or the servo amplifier. Do not look directly at light emitted from the tip of
SSCNET III connectors or SSCNET III cables of the Motion CPU or the servo
amplifier. Eye discomfort may be felt if exposed to the light. (Reference: SSCNET
III employs a Class 1 or equivalent light source as specified in JIS C 6802 and
IEC60825-1 (domestic standards in Japan).)
Do not remove the SSCNET III cable while power is supplied to the controller. Do
not look directly at light emitted from the tip of SSCNET III connectors or SSCNET
III cables. Eye discomfort may be felt if exposed to the light. (Reference: SSCNET
III employs a Class 1 or equivalent light source as specified in JIS C 6802 and
IEC60825-1 (domestic standards in Japan).)
Attach the cap to the SSCNET III connector after disconnecting the SSCNET III
cable. If the cap is not attached, dirt or dust may adhere to the connector pins,
resulting in deterioration connector properties, and leading to malfunction.
Make sure there are no mistakes in the wiring. Connecting differently to the way
specified in the manual can result in failures, such as the emergency stop not
being released. In order to prevent from occurring, please be sure to check that all
functions (such as the teaching box emergency stop, customer emergency stop,
and door switch) are working properly after the wiring setup is completed
Use the network equipments (personal computer, USB hub, LAN hub, etc) con-
firmed by manufacturer. The thing unsuitable for the FA environment (related with
conformity, temperature or noise) exists in the equipments connected to USB.
When using network equipment, measures against the noise, such as measures
against EMI and the addition of the ferrite core, may be necessary. Please fully
confirm the operation by customer. Guarantee and maintenance of the equipment
on the market (usual office automation equipment) cannot be performed.
To maintain the security (confidentiality, integrity, and availability) of the robot and
the system against unauthorized access, DoS*1 attacks, computer viruses, and
other cyberattacks from unreliable networks and devices via network, take appro-
priate measures such as firewalls, virtual private networks (VPNs), and antivirus
solutions.
Mitsubishi Electric shall have no responsibility or liability for any problems involv-
ing robot trouble and system trouble by unauthorized access, DoS attacks, com-
puter viruses, and other cyberattacks.
*1 DoS: A denial-of-service (DoS) attack disrupts services by overloading systems
or exploiting vulnerabilities, resulting in a denial-of-service (DoS) state.

Fig.2-2 ： Transportation of robot arm
1) Hook the wires to each of the four eyebolts attached to the transportation tool. (Make sure the bolts are
securely hooked.)
2) Lift with a crane to transport the robot to the designated location.
3) At this time, make sure that the wires, etc., do not interfere with the robot arm or the covers. Always place
the cloth, etc., at interfering places.
4) Be careful not to subject the robot to physical shock during transport.
5) After installing the robot (refer to Page 10, "2.2.3 Installation procedures"), remove the wires, the wire
hooks, transportation tool and fixing plate.
6) Always follow the above procedures and methods to transport the robot for secondary transportation, such
as when changing the installation position.
If the arm is directly suspended without using the specified transportation tool, or if it is suspended in the
work posture, the configuration devices could be damaged, and the transportation workers will be subject to
risk due to an inadequate center of gravity position.
When transporting a robot, always attach four wires.
To reattach the fixing plate again, set the axes of the robot to the positions according to
Table 2-2.
The robot should keep vertical. (not be horizontal)
It becomes the cause of the grease leakage or the trouble.
