FANUC is not and does not represent itself as an expert in safety
systems, safety equipment, or the specific safety aspects of your
company and/or its work force. It is the responsibility of the
owner, employer, or user to take all necessary steps to guarantee
the safety of all personnel in the workplace.
The appropriate level of safety for your application and
installation can best be determined by safety system professionals.
FANUC therefore, recommends that each customer consult with
such professionals in order to provide a workplace that allows for
the safe application, use, and operation of FANUC systems.
Additionally, as the owner, employer, or user of a robotic system,
it is your responsibility to arrange for the training of the operator
of a robot system to recognize and respond to known hazards
associated with your robotic system and to be aware of the
recommended operating procedures for your particular
application and robot installation.
FANUC therefore, recommends that all personnel who intend to
operate, program, repair, or otherwise use the robotics system be
trained in an approved FANUC training course and become
familiar with the proper operation of the system. Persons
responsible for programming the system-including the design,
implementation, and debugging of application programs-must be
familiar with the recommended programming procedures for your
application and robot installation.
The following guidelines are provided to emphasize the
importance of safety in the workplace.
IMPORTANT
Before operating, servicing or in any other way handling
the robot, the "FANUC Robot SAFETY HANDBOOK (B80687EN)" must be thoroughly studied.
s-1
SAFETY
B-82135EN/01
Considering safety
for your robot
installation
Safety is essential whenever robots are used. Keep in mind the
following factors with regard to safety:
• The safety of people and equipment
• Use of safety enhancing devices
• Techniques for safe teaching and manual operation of the
robot(s)
• Techniques for safe automatic operation of the robot(s)
• Regular scheduled inspection of the robot and workcell
• Proper maintenance of the robot
Keeping people and
equipment safe
The safety of people is always of primary importance in any
situation. However, equipment must be kept safe, too. When
prioritizing how to apply safety to your robotic system, consider
the following:
• People
• External devices
• Robot(s)
• Tooling
• Workpiece
Using safety enhancing
devices
Always give appropriate attention to the work area that surrounds
the robot. The safety of the work area can be enhanced by the
installation of some or all of the following devices:
• Safety fences, barriers, or chains
• Light curtains
• Interlocks
• Pressure mats
• Floor markings
• Warning lights
• Mechanical stops
• EMERGENCY STOP buttons
• DEADMAN switches
Setting up a safe
workcell
A safe workcell is essential to protect people and equipment.
Observe the following guidelines to ensure that the workcell is set
up safely. These suggestions are intended to supplement and not
replace existing federal, state, and local laws, regulations, and
guidelines that pertain to safety.
• Sponsor your personnel for training in approved FANUC
training course(s) related to your application. Never permit
untrained personnel to operate the robots.
• Install a lockout device to prevent unauthorized persons from
operating the robot.
• Use anti-tie-down logic to prevent the operator from bypassing
safety measures.
• Arrange the workcell so the operator faces the workcell and
can see what is going on inside the cell.
s-2
B-82135EN/01
SAFETY
• Clearly identify the work envelope of each robot in the system
with floor markings, signs, and special barriers. The work
envelope is the area defined by the maximum motion range of
the robot, including any tooling attached to the wrist flange that
extend this range.
• Position all controllers outside the robot work envelope.
• Never rely on software as the primary safety element.
• Install flashing lights and/or audible warning devices that
activate whenever the robot is operating, that is, whenever
power is applied to the servo drive system.
• Wherever possible, install safety fences to protect against
unauthorized entry by personnel into the work envelope.
• Install special guarding that prevents the operator from
reaching into restricted areas of the work envelope.
• Use interlocks.
• Use presence or proximity sensing devices such as light
curtains, mats, and capacitance and vision systems to enhance
safety.
• Periodically check the safety joints or safety clutches that can
be optionally installed between the robot wrist flange and
tooling. If the tooling strikes an object, these devices dislodge,
remove power from the system, and help to minimize damage
to the tooling and robot.
• Make sure all external devices are properly filtered, grounded,
shielded, and suppressed to prevent hazardous motion due to
the effects of electro-magnetic interference (EMI), radio
frequency interference (RFI), and electro-static discharge
(ESD).
• Make provisions for power lockout/tagout at the controller.
• Eliminate pinch points. Pinch points are areas where personnel
could get trapped between a moving robot and other
equipment.
• Provide enough room inside the workcell to permit personnel
to teach the robot and perform maintenance safely.
• Program the robot to load and unload material safely.
• If high voltage electrostatics are present, be sure to provide
appropriate interlocks, warning, and beacons.
• If materials are being applied at dangerously high pressure,
provide electrical interlocks for lockout of material flow and
pressure.
Staying safe while
teaching or manually
operating the robot
Advise all personnel who must teach the robot or otherwise
manually operate the robot to observe the following rules:
• Never wear watches, rings, neckties, scarves, or loose clothing
that could get caught in moving machinery.
• Know whether or not you are using an intrinsically safe teach
pendant if you are working in a hazardous environment.
• Before teaching, visually inspect the robot and work envelope
to make sure that no potentially hazardous conditions exist.
The work envelope is the area defined by the maximum motion

range of the robot. These include tooling attached to the wrist
flange that extends this range.
The area near the robot must be clean and free of oil, water, or
debris. Immediately report unsafe working conditions to the
supervisor or safety department.
FANUC recommends that no one enter the work envelope of a
robot that is on. However, if you must enter the work envelope,
be sure all safeguards are in place, and check the teach pendant
DEADMAN switch for proper operation. Take the teach
pendant with you, turn it on, and be prepared to release the
DEADMAN switch. Only the person with the teach pendant
should be in the work envelope.
Know the path that can be used to escape from a moving robot;
make sure the escape path is never blocked.
Isolate the robot from all remote control signals that can cause
motion while data is being taught.
Test any program being run for the first time in the following
manner:
WARNING
Stay outside the robot work envelope whenever a
program is being run. Failure to do so can result in injury.
- Using a low motion speed, single step the program for at least
one full cycle.
- Using a low motion speed, test run the program continuously for
at least one full cycle.
- Using the programmed speed, test run the program continuously
for at least one full cycle.
- Make sure all personnel are outside the work envelope before
running production.
Staying safe during
production operation
Advise all personnel who operate the robot during production to
observe the following rules:
• Know the entire workcell area. The workcell includes the robot
and its work envelope, plus the area occupied by all external
devices and other equipment with which the robot interacts.
• Understand the complete task the robot is programmed to
perform before initiating production operation.
• Make sure all personnel are outside the work envelope before
operating the robot.
• Never enter or allow others to enter the work envelope during
production operation of the robot.
• Know the location and status of all switches, sensors, and
control signals that could cause the robot to move.
• Know where the EMERGENCY STOP buttons are located on
both the robot control and external control devices. Be
prepared to press these buttons in an emergency.
• Never assume that a program is complete if the robot is not
s-4
B-82135EN/01
SAFETY
moving. The robot could be waiting for an input signal that will
permit it to continue activity.
• If the robot is running in a pattern, do not assume it will
continue to run in the same pattern.
• Never try to stop the robot, or break its motion, with your body.
The only way to stop robot motion immediately is to press an
EMERGENCY STOP button located on the controller panel,
teach pendant, or emergency stop stations around the workcell.
Staying safe during
inspection
When inspecting the robot, be sure to:
• Turn off power at the controller.
• Lock out and tag out the power source at the controller
according to the policies of your plant.
• Turn off the compressed air source and relieve the air pressure.
• If robot motion is not needed for inspecting the electrical
circuits, press the EMERGENCY STOP button on the operator
panel.
• Never wear watches, rings, neckties, scarves, or loose clothing
that could get caught in moving machinery.
• If power is needed to check the robot motion or electrical
circuits, be prepared to press the EMERGENCY STOP button,
in an emergency.
Staying safe during
maintenance
When performing maintenance on your robot system, observe the
following rules:
• Never enter the work envelope while the robot or a program is
in operation.
• Before entering the work envelope, visually inspect the
workcell to make sure no potentially hazardous conditions
exist.
• Never wear watches, rings, neckties, scarves, or loose clothing
that could get caught in moving machinery.
• Consider all or any overlapping work envelopes of adjoining
robots when standing in a work envelope.
• Test the teach pendant for proper operation before entering the
work envelope.
• If it is necessary for you to enter the robot work envelope while
power is turned on, you must be sure that you are in control of
the robot. Be sure to take the teach pendant with you, press the
DEADMAN switch, and turn the teach pendant on. Be
prepared to release the DEADMAN switch to turn off servo
power to the robot immediately.
• Whenever possible, perform maintenance with the power
turned off. Before you open the controller front panel or enter
the work envelope, turn off and lock out the 3-phase power

source at the controller.
WARNING
Lethal voltage is present in the controller WHENEVER IT
IS CONNECTED to a power source. Be extremely careful
to avoid electrical shock.
HIGH VOLTAGE IS PRESENT at the input side whenever
the controller is connected to a power source. Turning the
disconnect or circuit breaker to the OFF position removes
power from the output side of the device only.
• Release or block all stored energy. Before working on the
pneumatic system, shut off the system air supply and purge the
air lines.
• Isolate the robot from all remote control signals. If
maintenance must be done when the power is on, make sure the
person inside the work envelope has sole control of the robot.
The teach pendant must be held by this person.
• Make sure personnel cannot get trapped between the moving
robot and other equipment. Know the path that can be used to
escape from a moving robot. Make sure the escape route is
never blocked.
• Use blocks, mechanical stops, and pins to prevent hazardous
movement by the robot. Make sure that such devices do not
create pinch points that could trap personnel.
WARNING
Do not try to remove any mechanical component from the
robot before thoroughly reading and understanding the
procedures in the appropriate manual. Doing so can result
in serious personal injury and component destruction.
• Be aware that when you remove a servomotor or brake, the
associated axis will fall if it is not supported or resting on a hard
stop.
• When replacing or installing components, make sure dirt and
debris do not enter the system.
• Use only specified parts for replacement. To avoid fires and
damage to parts in the controller, never use nonspecified fuses.
s-6
B-82135EN/01
SAFETY
• Before restarting a robot, make sure no one is inside the work
envelope; be sure that the robot and all external devices are
operating normally.
• Use appropriate lighting for maintenance work. Take care that
the lighting does not create new dangerous situations.
• If it is necessary to operate the robot during the inspection, pay
careful attention to the robot's motion and be sure to press the
EMERGENCY STOP button immediately when necessary.
• Be careful not to slip on spilled grease during maintenance.
• Do not climb on the robot.
• Some components might be hot. Take care when working on
servo motors or inside the controller. Wear protective clothing
(heart-resistant gloves, etc.) when working on components that
are hot.
• After replacing components, be sure to tighten screws and
fasteners that were loosened.
• The motor and reducer are heavy. Be careful when replacing
them. If the robot collides with a mechanical hard stop, replace
the mechanical hard stop even if it does not seem to be
damaged.
• After replacing parts or making adjustments, be sure to test run
the robot according to the following procedure.
1. Using a low motion speed, single step the program for
at least one full cycle.
2. Using a low motion speed, test run the program
continuously for at least one full cycle.
3. As speed is increased the path may vary slightly. Run
through the program at 5-10% intervals up to 100%.
4. Using the programmed speed, test run the program
continuously for at least one full cycle.
Make sure all personnel are outside the fence before test
running.
• After maintenance work, clean the area around the robot of oil,
water, and debris.

3. PERIODIC MAINTENANCE
NOTE
If greasing is performed incorrectly, the internal pressure
of the grease bath may suddenly increase, possibly
causing damage to the seal, which would in turn lead to
grease leakage and abnormal operation. When
performing greasing, therefore, observe the following
cautions.
1. Before starting to grease, open the grease outlet
(remove the plug or bolt from the grease outlet).
2. Supply grease slowly without applying excessive force,
using a manual pump.
3. Whenever possible, avoid using a compressed-air
pump, powered by the factory air supply. If the use of
a compressed air pump is unavoidable, restrict the
maximum greasing rate to 15 ml/s and the greasing
pressure to 7.35 MPa (75 kgf/cm2).
4. Use grease only of the specified type. Grease of a type
other than that specified may damage the reducer or
lead to other problems.
5. After greasing, confirm that no grease is leaking from
the grease outlet and that the grease bath is not
pressurized, then close the grease outlet.
6. To prevent accidents caused by slipping, completely
remove any excess grease from the floor or robot.

4.1 OVERVIEW
MAINTENANCE
4. TROUBLESHOOTING
The cause of a failure in the mechanical unit may be difficult to
localize, because failures can arise from many interrelated factors.
If you fail to take the correct measures, the failure may be
aggravated. So, it is necessary to analyze the symptoms of the
failure precisely so that the true cause can be found.

4.2 FAILURE
AND CAUSE
MAINTENANCE
B-82135EN/01
Table. 4.2 lists the major failures that may occur in the mechanical
unit and their probable causes. If you cannot pinpoint a failure
cause or which measures to apply, contact FANUC. If you have to
replace components or make adjustments to repair the failure, see
Section 5, 6, and 8.
Table. 4.2 Failures and Causes
Symptom
Vibration
Noise
Description
Cause
Measure
- As the robot
operates, its base
plate lifts off the
floor plate.
- There is a gap
between the base
plate and the floor
plate.
- There is a crack in
the weld that fastens
the base plate to the
floor plate.
[Base plate and floor plate fastening]
- It is likely that the base plate is not
securely fastened to the floor plate
because of poor welding.
- If the base plate is not securely
fastened to the floor plate, it lifts as
the robot operates, allowing the base
and floor plates to strike each other
which, in turn, leads to vibration.
- Re-weld the base plate to the floor
plate.
- If the weld is not strong enough,
increase its width and length.
- The J1 base lifts off
the base plate as the
robot operates.
- There is a gap
between the J1 base
and base plate.
- A J1 base retaining
bolt is loose.
[J1 base fastening]
- It is likely that the robot J1 base is
not securely fastened to the base plate.
- Probable causes are a loose bolt, an
insufficient degree of surface flatness,
or foreign material caught between
the base plate and floor plate.
- If the robot is not securely fastened
to the base plate, the J1 base lifts the
base plate as the robot operates,
allowing the base and floor plates to
strike each other which, in turn, leads
to vibration.
- If a bolt is loose, apply loctite and
tighten it to the appropriate torque.
- Adjust the base plate surface
flatness to within the specified
tolerance.
- If there is any foreign matter
between the J1 base and base plate,
remove it.
- As the robot operates, the rack or
floor on which the robot is mounted
vibrates.
- Apply epoxy to the
floor surface and
reinstall the plate.
[Rack or floor]
- It is likely that the rack or floor is not
sufficiently rigid.
- If the rack or floor is not sufficiently
rigid, reaction from the robot deforms
the rack or floor, leading to vibration.
- Reinforce the rack or floor to make
it more rigid.
- If it is impossible to reinforce the
rack or floor, modify the robot
control program; doing so might
reduce the amount of vibration.

Table. 4.2 Failures and Causes
Symptom
Vibration
Noise
Description
Cause
Measure
- Vibration becomes
more serious when
the robot adopts a
specific posture.
- If the operating
speed of the robot is
reduced, vibration
stops.
- Vibration is most
noticeable when the
robot is
accelerating.
- Vibration occurs
when two or more
axes operate at the
same time.
[Overload]
- It is likely that the load on the robot
is greater than the maximum rating.
- It is likely that the robot control
program is too demanding for the
robot hardware.
- Check the maximum load that the
robot can handle once more. If the
robot is found to be overloaded,
reduce the load, or modify the robot
control program.
- Vibration in a specific portion can
be reduced by modifying the robot
control program while slowing the
robot and reducing its acceleration
(to minimize the influence on the
entire cycle time).

Table. 4.2 Failures and Causes
Symptom
Vibration
Noise
Description
Cause
Measure
- Vibration was first
noticed after the
robot collided with
an object or the
robot was
overloaded for a
long period.
- The grease of the
vibrating axis has
not been exchanged
for a long period.
[Broken gear, bearing, or reducer]
- It is likely that collision or overload
applied an excessive force on the
drive mechanism, thus damaging the
gear tooth surface or rolling surface of
a bearing, or reducer.
- It is likely that prolonged use of the
robot while overloaded caused
fretting of the gear tooth surface or
rolling surface of a bearing, or reducer
due to resulting metal fatigue.
- It is likely that foreign matter caught
in a gear, bearing, or within a reducer
caused damage on the gear tooth
surface or rolling surface of the
bearing, or reducer.
- It is likely that, because the grease
has not been changed for a long
period, fretting occurred on the gear
tooth surface or rolling surface of a
bearing, or reducer due to metal
fatigue. These factors all geneate
cyclic vibration and noise.
- Operate one axis at a time to
determine which axis is vibrating.
- Find the source of the vibration
while referring to the drive
mechanism drawing of each axis
given in the related maintenance
manual.
- Remove the motor, and check
whether there are any fretting on a
gear tooth surface. If any fretting is
found, replace the gear.
Note) Even a small amount of
damage on a gear tooth surface can
generate a large amount of noise.
Therefore, it is necessary to check
each gear tooth surface carefully.
- Check whether any other gear in
the drive mechanism is abnormal. If
all the gears are found to be
satisfactory, the reducer must be
replaced.
- If there is foreign matter caught in
a gear, or if a gear tooth is missing,
replace the gear. Also, remove all
the grease from the gear box and
wash the inside of the gear box.
- After replacing the gear or reducer,
add an appropriate amount of grease.
- If nothing changes after a gear or
reducer is replaced, it is likely that a
bearing is damaged.
- Using the robot within its
maximum rating prevents problems
with the drive mechanism.
- Regularly changing the grease with
a specified type can help prevent
problems.

Description
Cause
Measure
- The cause of
problem cannot be
identified from
examination of the
floor, rack, or
mechanical section.
[Controller, cable, and motor]
- If a failure occurs in a controller
circuit, preventing control commands
from being supplied to the motor
normally, or preventing motor
information from being sent to the
controller normally, vibration might
occur.
- If the pulse coder develops a fault,
vibration might occur because
information about the motor position
cannot be transferred to the controller
accurately.
- If the motor becomes defective,
vibration might occur because the
motor cannot deliver its rated
performance.
- If a power line in a movable cable of
the mechanical section has an
intermittent break, vibration might
occur because the motor cannot
accurately respond to commands.
- If a pulse coder wire in a movable
part of the mechanical section has an
intermittent break, vibration might
occur because commands cannot be
sent to the motor accurately.
- If a connection cable between them
has an intermittent break, vibration
might occur.
- If the power source voltage drops
below the rating, vibration might
occur.
- If a robot control parameter is set to
an invalid value, vibration might
occur.
- Refer to the R-J3i MODEL B
Controller Maintenance Manual for
troubleshooting related to the
controller and amplifier.
- Replace the pulse coder for the
motor of the axis that is vibrating,
and check whether the vibration still
occurs.
- Also, replace the motor of the axis
that is vibrating, and check whether
vibration still occurs.
- Check that the robot is supplied
with the rated voltage.
- Check whether the sheath of the
power cord is damaged. If so,
replace the power cord, and check
whether vibration still occurs.
- Check whether the sheath of the
cable connecting the mechanical
section and controller is damaged. If
so, replace the connection cable, and
check whether vibration still occurs.
- If vibration occurs only when the
robot assumes a specific posture, it
is likely that a cable in the
mechanical unit is broken.
- Shake the movable part cable while
the robot is at rest, and check
whether an alarm occurs. If an alarm
or any other abnormal condition
occurs, replace the mechanical unit
cable.
- Check that the robot control
parameter is set to a valid value. If it
is set to an invalid value, correct it.
Contact FANUC for further
information if necessary.
- There is some
relationship
between the
vibration of the
robot and the
operation of a
machine near the
robot.
[Noise from a nearby machine]
- If the robot is not grounded properly,
electrical noise is induced on the
grounding wire, preventing
commands from being transferred
accurately, thus leading to vibration.
- If the robot is grounded at an
unsuitable point, its grounding
potential becomes unstable, and noise
is likely to be induced on the
grounding line, thus leading to
vibration.
- Connect the grounding wire firmly
to ensure a reliable ground potential
and prevent extraneous electrical
noise.

Rattling
Description
Cause
Measure
- While the robot is
not supplied with
power, pushing it
with the hand causes
part of the
mechanical unit to
wobble.
- There is a gap on
the mounting
surface of the
mechanical unit.
[Mechanical section coupling bolt]
- It is likely that overloading or a
collision has loosened a mounting
bolt in the robot mechanical section.
Check that the following bolts for
each axis are tight. If any of these
bolts is loose, apply loctite and
tighten it to the appropriate torque.
- Motor retaining bolt
- Reducer retaining bolt
- Reducer shaft retaining bolt
- Base retaining bolt
- Arm retaining bolt
- Casting retaining bolt
- End effecter retaining bolt
- Backlash is greater
than the tolerance
stated in the
applicable
maintenance
manual.
[Increase in backlash]
- It is likely that excessive force
applied to the drive mechanism, due
to a collision or overloading, has
broken a gear or the inside of the
reducer, resulting in an increase in the
amount of backlash.
- It is likely that prolonged use
without changing the grease has
caused the tooth surfaces of a gear and
the inside of the reducer to wear out,
resulting in an increase in the amount
of backlash.
- Operate one axis at a time to
determine which axis has the
increased backlash.
- Remove the motor, and check
whether any of its gears are broken.
If any gear is broken, replace it.
- Check whether any other gear of
the drive mechanism is damage. If
there is no damage gear, replace the
reducer.
- If the reducer is broken, or if a gear
tooth is missing, replace the relevant
component. Also, remove all the
grease from the gear box and wash
the inside of the gear box.
- After replacing the gear or reducer,
add an appropriate amount of grease.

overheating
Description
Cause
Measure
- The ambient
temperature of the
installation location
increases, causing
the motor to
overheat.
- After a cover was
attached to the
motor, the motor
overheated.
- After the robot
control program or
the load was
changed, the motor
overheated.
[Ambient temperature]
- It is likely that a rise in the ambient
temperature or attaching the motor
cover prevented the motor from
releasing heat efficiently, thus leading
to overheating.
[Operating condition]
- It is likely that the robot was
operated with the maximum average
current exceeded.
The teach pendant can be used to
monitor the average current. Check
the average current when the robot
control program is running. The
allowable average current is
specified for the robot according to
its ambient temperature. Contact
FANUC for further information.
- Relaxing the robot control program
and conditions can reduce the
average current, thus preventing
overheating.
- Reducing the ambient
temperature is the most effective
means of preventing overheating.
- Having the surroundings of the
motor well ventilated enables the
motor to release heat efficiently,
thus preventing overheating. Using a
fan to direct air at the motor is also
effective.
- If there is a source of heat near the
motor, it is advisable to install
shielding to protect the motor from
heat radiation.
- After a control
parameter was
changed, the motor
overheated.
[Parameter]
- If data input for a workpiece is
invalid, the robot cannot be
accelerated or decelerated normally,
so the average current increases,
leading to overheating.
- Input an appropriate parameter as
described in the manual.
- Symptom other
than stated above
[Mechanical section problems]
- It is likely that problems occurred in
the mechanical unit drive mechanism,
thus placing an excessive load on the
motor.
[Motor problems]
- It is likely that a failure of the motor
brake resulted in the motor running
with the brake applied, thus placing
an excessive load on the motor.
- It is likely that a failure of the motor
prevented it from delivering its rated
performance, thus causing an
excessive current to flow through the
motor.
Repair the mechanical unit while
referring to the above descriptions of
vibration, noise, and rattling.
- Check that, when the servo system
is energized, the brake is released.
- If the brake remains applied to the
motor all the time, replace the motor.
- If the average current falls after the
motor is replaced, it indicates that
the first motor was faulty.

Description
Cause
Measure
- Grease is leaking
from the mechanical
unit.
[Poor sealing]
- Probable causes are a crack in the
casting, a broken O-ring, a damaged
oil seal, or a loose seal bolt.
- A crack in a casting can occur due to
excessive force that might be caused
in collision.
- An O-ring can be damaged if it is
trapped or cut during disassembling
or re-assembling.
- An oil seal might be damaged if
extraneous dust scratches the lip of
the oil seal.
- A loose seal bolt or a plug might
allow grease to leak along the threads.
- Problems with the grease nipple or
threads.
- If a crack develops in the casting,
sealant can be used as a quick-fix to
prevent further grease leakage.
However, the component should be
replaced as soon as possible,
because the crack might extend.
- O-rings are used in the locations
listed below. Refer to the relevant
parts manual for detailed
descriptions of their replacement.
- Motor coupling section
- Reducer (case and shaft) coupling
section
- Wrist coupling section
- J3 arm coupling section
- Inside the wrist
- Oil seals are used in the locations
stated below. Refer to the relevant
parts manual for detailed
descriptions of their replacement.
- J1 axis cable pipe joint
- Inside the reducer
- Inside the wrist
- J2/J3-axis connecting section
- Seal bolts are used in the locations
stated below. Refer to the relevant

descriptions of their replacement.
- J3-axis ring connecting section
- Grease drain outlet
Dropping axis
- An axis drops
because the brake
does not function.
- An axis drops
gradually when it
should be at rest.
[Brake drive relay and motor]
- It is likely that brake drive relay
contacts are stuck to each other to
keep the brake current flowing, thus
preventing the brake from operating
when the motor is deenergized.
- It is likely that the brake shoe has
worn out or the brake main body is
damaged, preventing the brake from
operating efficiently.
- It is likely that oil or grease has
entered the motor, causing the brake
to slip.
—— 36 ——
- Check whether the brake drive
relay contacts are stuck to each
other, as explained in the relevant
manual. If they are found to be stuck,
replace the relay.
- If the brake shoe is worn out, if the
brake main body is damaged, or if
oil or grease has entered the motor,

- The repeatability is
not within the
tolerance.
[Mechanical section problems]
- If the repeatability is unstable,
probable causes are a failure in the
drive mechanism or a loose bolt.
- If the repeatability becomes stable it
is likely that a collision imposed an
excessive load, leading to slipping on
the base surface or the mating surface
of an arm or reducer.
- If the repeatability is unstable,
repair the mechanical section by
referring to the above descriptions of
vibration, noise, and rattling.
- If the repeatability is stable, correct
the taught program. Variation will
not occur unless another collision
occurs.
- Displacement
occurs only in a
specific peripheral
unit.
[Peripheral unit displacement]
- It is likely that an external force was
applied to the peripheral unit, thus
shifting its position relative to the
robot.
- Correct the setting of the peripheral
unit position.
- Correct the taught program.
- Displacement
occurred after a
parameter was
changed.

5.1 AXIS LIMITS
SETUP
MAINTENANCE
B-82135EN/01
Axis limits define the motion range of the robot.
The operating range of the robot axes can be restricted because of :
• Work area limitations
• Tooling and fixture interference points
• Cable and hose lengths
There are three methods used to prevent the robot from going
beyond the necessary motion range.
These are
• Axis limit software settings (All axes)
• Axis limit hardstops ((J1, J2, J3-axis) optional)
• Axis limit switches ((J1, J2, J3-axis) optional)
NOTE
1. Changing the movable range of any axis affects the
operation range of the robot. To avoid trouble, carefully
consider a possible effect of the change to the movable
range of each axis in advance. Otherwise, it is likely
that an unexpected condition occurs; for example, an
alarm may occur in a previous taught position.
2. For the J1, J2, and J3 axes, do not count merely on
software-based limits to the movable range when
changing the movable range of the robot. Use
mechanical stoppers together so that damage to
peripheral equipment and injuries to human bodies can
be avoided. In this case, make the software-specified
limits match the limits based on the mechanical
stoppers.
3. Mechanical stoppers are physical obstacles. The robot
cannot move beyond them.
For the J1, J2, and J3 axes, it is possible to re-position
the mechanical stoppers.
For J5-axis, the mechanical stoppers are fixed.
For the J4 and J6 axes, only software-specified limits
are available.
4. For changing J2 and J3 axes interference angles, only
mechanical stoppers are available; a softwarespecified movable range cannot be changed.
5. Movable mechanical stoppers (J1, J2, and J3 axes)
are deformed in a collision to stop the robot. Once a
stopper is subject to a collision, it can no longer assure
its original strength and, therefore, may not stop the
robot. When this happens, replace it with a new one.

5.3 MASTERING
Mastering is an operation performed to associate the angle of each
robot axis with the pulse count value supplied from the absolute
pulse coder connected to the corresponding axis motor. To be
specific, mastering is an operation for obtaining the pulse count
value corresponding to the zero position.
5.3.1 General
The current position of the robot is determined according to the
pulse count value supplied from the pulse coder on each axis.
Mastering is factory-performed. It is unnecessary to perform
mastering in daily operations.
However, mastering becomes necessary after:
• Motor replacement.
• Pulse coder replacement.
• Reducer replacement.
• Cable replacement.
• Batteries for pulse count backup in the mechanical unit have
gone dead.
NOTE
Robot data (including mastering data) and pulse coder
data are backed up by their respective backup batteries.
Data will be lost if the batteries go dead. Replace the
batteries in the control and mechanical units periodically.
An alarm will be issued to warn the user of a low battery
voltage.
Mastering method
Table. 5.3.1 Types of Mastering
Jig position mastering
This is performed using a mastering jig before the machine is shipped
from the factory.
Zero-position mastering
(eye mark mastering)
This is performed with all axes set at the 0-degree position.
A zero-position mark (eye mark) is attached to each robot axis.
This mastering is performed with all axes aligned to their respective eye
marks.
Quick mastering
This is performed at a user-specified position. The corresponding count
value is obtained from the rotation speed of the pulse coder connected to
the relevant motor and the rotation angle within one rotation. Simplified
mastering uses the fact that the absolute value of a rotation angle within
one rotation will not be lost.
Single-axis mastering
This is performed for one axis at a time. The mastering position for each
axis can be specified by the user. This is useful in performing mastering
on a specific axis.
Mastering data entry
Mastering data is entered directly.
—— 58 ——
B-82135EN/01
MAINTENANCE
5. ADJUSTMENTS
Once mastering is performed, it is necessary to carry out
positioning, or calibration. Positioning is an operation in which the
control unit reads the current pulse count value to sense the current
position of the robot.
NOTE
If mastering is performed incorrectly, the robot may
behave unexpectedly. This is very dangerous. So, the
positioning screen is designed to appear only when the
$MASTER_ENB system variable is 1 or 2. After
performing positioning, press F5 [DONE] on the
positioning screen. The $MASTER_ENB system variable
is reset to 0 automatically, thus hiding the positioning
screen.
5.3.2 Resetting
Alarms and

Mastering
Before performing mastering because a motor is replaced, it is
necessary to release the relevant alarm and display the positioning
menu.

TION
Washing and degreasing
the surfaces to be sealed
1. After dismounting the reducer from the arm, apply releasant
(Loctite Gasket Remover) to the arm's surface from which the
reducer was dismounted, then wait until the sealant (Loctite
518) becomes softened (for about 10 minutes). Remove the
softened sealant from the surface using a spatula.
2. Blow air onto the surface to be sealed to remove dust from the
tapped holes.
3. Sufficiently degrease the reducer's surface to be sealed and the
arm's surface to be sealed, using a cloth dampened with
alcohol.
4. Polish the arm's surface to be sealed with an oil stone, and
degrease it with alcohol again.
NOTE
Oil may drip from the inside of the reducer. After
degreasing, make sure that no oil is dripping.
Applying sealant
5. Make sure that the reducer and the arm are dry (with no alcohol
remaining). If they are still wet with alcohol, wipe them dry.
6. Apply sealant (Loctite 518) to the surfaces.
NOTE
The portions to which sealant is to be applied vary from
one axis to another. See descriptions about reducer
replacement for the relevant axes for details.
Assembling
7. To prevent dust from sticking to the portions to which sealant
was applied, mount the reducer as quickly as possible after
sealant application. Be careful not to touch the applied sealant.
If sealant was wiped off, apply again.
8. After mounting the reducer, fasten it with bolts and washers
quickly so that the mated surfaces get closer.
NOTE
Do not grease the reducer before the sealant sets, as it
may allow grease to leak. Before greasing, wait for about
at least one hour after the reducer is mounted.

Replace the cables every four years. When the cable is broken or
damaged, or shows signs of wear, replace it according to this
chapter.
Precaution to be
observed when handling
the pulse coder cable
The pulse coder cable is provided with a marking tie, as shown
below, to warn against disconnecting the cable during
transportation, installation, or maintenance. If the cable with the
marking tie is disconnected, mastering must be performed again.
Therefore, do not disconnect the cable except when replacement
of the cable is necessary.
The J1-axis, J2-axis and J3-axis motors are provided with a pulse
coder connector cover, as shown in Fig. 8 (b), to protect the
connectors. Before removing the connectors for cable replacement
or other purposes, remove the covers. In this case, turning the bolt
may also turn the cover, possibly causing damage to the connector.
When removing the cover, hold it to prevent it from turning.

MENT
This section describes a procedure for periodically replacing all
the (full-option) mechanical unit cables.
If you need to replace a specific cable (because, for example, it is
damaged), do so by referencing this section. See Section 7.2 for
the configuration of the mechanical unit cables.
Cable replacement makes it necessary to perform mastering.
Before attempting replacement, therefore, see Section 5.3.
Replacement procedure
1. Place all the robot axes in their 0-degree position, then set the
control unit power switch to off.
2. Detach, from the connector panel on the rear of the J1-axis
base, the cable leading to the control unit. Remove the
connector panel from the J1 base, then detach all the cable
tubes from the connector panel. When detaching a HARTING
connector, leave its housing on the connector panel; remove
the inserts together with the cable. If the housing is left on the
cable, the cable cannot be pulled out through the J1 axis piping
(Fig. 8.2 (a)).
3. When the robot has J1-axis limit switches (option), remove the
limit switch for the J1-axis from the plate of the J1-axis base,
and remove the terminal in the switch, then pull out the cable
from the cast through hole (Fig. 8.2 (b)).
4. Remove all connectors from the J1-axis through J6-axis
motors. For the precautions that must be taken, see "Precaution
to be observed when handling the pulse coder cable" at the
beginning of Chapter 8.
5. When the robot has the J2-axis, J3-axis, and interference angle
limit switches (option), remove the limit switches from the
mounting plate and remove the terminals in the J2-axis and J3axis limit switches (Fig. 8.2(c)).
6. When the robot has the DS/DP cable (option), remove the cable
from the J2-axis base connector panel (Fig. 8.2(d)).
7. Run the J2-axis and J3-axis motor and pulse coder cables, J2axis and J3-axis limit switch cables (option), and J2-axis DS/
DP cables (option) into the J2 base.
8. Remove the connector panel on the back of the J3-axis casing
(Fig. 8.2(e)).
9. Remove the lower plate 1 of the J3-axis casing (Fig. 8.2(e)).
10.Remove the plate 2 that covers the cable on the J2-axis arm
(Fig. 8.2(e)).
11.Remove the heat-shrink tubing that covers connectors and
remove the interference angle limit switch cable and the J1axis, J2-axis, and J3-axis limit switch cable connectors (Fig.
8.2(c)).
12.Remove the plate 3 that secures the cable on the back of the J2axis arm (Fig. 8.2(e)).
13.Remove the plate 4 that secures the cable on the top of the J2axis base (Fig. 8.2(f)).
14.Remove the plate 5 on the J2-axis base (Fig. 8.2(f)).
