INSTRUCTION MANUAL
Troubleshooting
BFP-A8871-U
This instruction manual apply to both the CR-750-Q/CR751-Q/CR760-Q controller corresponding
to iQ Platform, and the CR-750-D/CR751-D/CR760-D controller of standalone type.

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 connect the Handy GOT to a programmable controller when using an iQ
Platform compatible product with the CR7xx-Q controller. 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 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 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.
