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.

Safety Precautions

CAUTION

WARNING

CAUTION

DANGER

CAUTION

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.

DANGER

CAUTION

WARNING

CAUTION

WARNING

CAUTION

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.

WARNING

CAUTION

DANGER

CAUTION
