SAFETY PRECAUTIONS

B-82725EN-1/07

SAFETY PRECAUTIONS
For the safety of the operator and the system, follow all safety precautions when operating a robot and its
peripheral devices installed in a work cell.
In addition, refer to the “FANUC Robot SAFETY HANDBOOK (B-80687EN)”.

WORKING PERSON

The personnel can be classified as follows.

Operator:
• Turns robot controller power ON/OFF
• Starts robot program from operator’s panel
Programmer or teaching operator:
• Operates the robot
• Teaches robot inside the safety fence
Maintenance engineer:
• Operates the robot
• Teaches robot inside the safety fence
• Maintenance (adjustment, replacement)
-

An operator cannot work inside the safety fence.
A programmer, teaching operator, and maintenance engineer can work inside the safety fence. The
working activities inside the safety fence include lifting, setting, teaching, adjusting, maintenance,
etc..
To work inside the fence, the person must be trained on proper robot operation.

During the operation, programming, and maintenance of your robotic system, the programmer, teaching
operator, and maintenance engineer should take additional care of their safety by using the following
safety precautions.
-

Use adequate clothing or uniforms during system operation
Wear safety shoes
Use helmet

WORKING PERSON SAFETY

Working person safety is the primary safety consideration. Because it is very dangerous to enter the
operating space of the robot during automatic operation, adequate safety precautions must be observed.
The following lists the general safety precautions. Careful consideration must be made to ensure
working person safety.
(1) Have the robot system working persons attend the training courses held by FANUC.
FANUC provides various training courses.

Contact our sales office for details.

B-82725EN-1/07

(2) Even when the robot is stationary, it is possible that the robot is still in a ready to move state, and is
waiting for a signal. In this state, the robot is regarded as still in motion. To ensure working
person safety, provide the system with an alarm to indicate visually or aurally that the robot is in
motion.
(3) Install a safety fence with a gate so that no working person can enter the work area without passing
through the gate. Install an interlocking device, a safety plug, and so forth in the safety gate so that
the robot is stopped as the safety gate is opened.
The controller is designed to receive this interlocking signal of the door switch. When the gate
is opened and this signal received, the controller stops the robot (Please refer to "STOP
TYPE OF ROBOT" in SAFETY for detail of stop type). For connection, see Fig.2 (a) and
Fig.2 (b).
(4) Provide the peripheral devices with appropriate grounding (Class A, Class B, Class C, and Class D).
(5) Try to install the peripheral devices outside the work area.
(6) Draw an outline on the floor, clearly indicating the range of the robot motion, including the tools
such as a hand.
(7) Install a mat switch or photoelectric switch on the floor with an interlock to a visual or aural alarm
that stops the robot when a working person enters the work area.
(8) If necessary, install a safety lock so that no one except the working person in charge can turn on the
power of the robot.
The circuit breaker installed in the controller is designed to disable anyone from turning it on
when it is locked with a padlock.
(9) When adjusting each peripheral device independently, be sure to turn off the power of the robot

OPERATOR SAFETY

The operator is a person who operates the robot system. In this sense, a worker who operates the teach
pendant is also an operator. However, this section does not apply to teach pendant operators.
(1) If you do not have to operate the robot, turn off the power of the robot controller or press the
EMERGENCY STOP button, and then proceed with necessary work.
(2) Operate the robot system at a location outside of the safety fence
(3) Install a safety fence with a safety gate to prevent any worker other than the operator from entering
the work area unexpectedly and to prevent the worker from entering a dangerous area.
(4) Install an EMERGENCY STOP button within the operator’s reach.
The robot controller is designed to be connected to an external EMERGENCY STOP button.
With this connection, the controller stops the robot operation (Please refer to "STOP TYPE
OF ROBOT" in SAFETY for detail of stop type), when the external EMERGENCY STOP
button is pressed. See the diagram below for connection.

SAFETY OF THE PROGRAMMER

While teaching the robot, the operator must enter the work area of the robot.
the safety of the teach pendant operator especially.

The operator must ensure

(1) Unless it is specifically necessary to enter the robot work area, carry out all tasks outside the area.
(2) Before teaching the robot, check that the robot and its peripheral devices are all in the normal
operating condition.
(3) If it is inevitable to enter the robot work area to teach the robot, check the locations, settings, and
other conditions of the safety devices (such as the EMERGENCY STOP button, the DEADMAN
switch on the teach pendant) before entering the area.
(4) The programmer must be extremely careful not to let anyone else enter the robot work area.

SAFETY PRECAUTIONS

B-82725EN-1/07

The operator panel is provided with an emergency stop button and a key switch (mode switch) for selecting the
automatic operation mode (AUTO) and the teach modes (T1 and T2). Before entering the inside of the safety
fence for the purpose of teaching, set the switch to a teach mode, remove the key from the mode switch to prevent
other people from changing the operation mode carelessly, then open the safety gate. If the safety gate is opened
with the automatic operation mode set, the robot stops (Please refer to "STOP TYPE OF ROBOT" in SAFETY for
detail of stop type). After the switch is set to a teach mode, the safety gate is disabled. The programmer should
understand that the safety gate is disabled and is responsible for keeping other people from entering the inside of
the safety fence.
The teach pendant is provided with a DEADMAN switch as well as an emergency stop button. These button and
switch function as follows:
(1) Emergency stop button: Causes an emergency stop (Please refer to "STOP TYPE OF ROBOT" in SAFETY
for detail of stop type) when pressed.
(2) DEADMAN switch: Functions differently depending on the mode switch setting status.
(a) Automatic operation mode: The DEADMAN switch is disabled.
(b) Teach mode: Servo power is turned off when the operator releases the DEADMAN switch or when the
operator presses the switch strongly.
Note) The DEADMAN switch is provided to stop the robot when the operator releases the teach pendant or
presses the pendant strongly in case of emergency. The R-30iA Mate employs a 3-position
DEADMAN switch, which allows the robot to operate when the 3-position DEADMAN switch is pressed
to its intermediate point. When the operator releases the DEADMAN switch or presses the switch
strongly, the robot stops immediately.
The operator’s intention of starting teaching is determined by the controller through the dual operation of setting the
teach pendant enable/disable switch to the enable position and pressing the DEADMAN switch. The operator
should make sure that the robot could operate in such conditions and be responsible in carrying out tasks safely.
The teach pendant, operator panel, and peripheral device interface send each robot start signal. However the
validity of each signal changes as follows depending on the mode switch of the operator panel, the teach pendant
enable/disable switch and the remote condition on the software.

(5) To start the system using the operator’s panel, make certain that nobody is the robot work area and
that there are no abnormal conditions in the robot work area.
(6) When a program is completed, be sure to carry out a test run according to the procedure below.
(a) Run the program for at least one operation cycle in the single step mode at low speed.
(b) Run the program for at least one operation cycle in the continuous operation mode at low
speed.
(c) Run the program for one operation cycle in the continuous operation mode at the intermediate
speed and check that no abnormalities occur due to a delay in timing.
(d) Run the program for one operation cycle in the continuous operation mode at the normal
operating speed and check that the system operates automatically without trouble.
(e) After checking the completeness of the program through the test run above, execute it in the
automatic operation mode.

(7) While operating the system in the automatic operation mode, the teach pendant operator should
leave the robot work area.

2.3

SAFETY OF THE MAINTENANCE ENGINEER

For the safety of maintenance engineer personnel, pay utmost attention to the following.
(1) During operation, never enter the robot work area.
(2) Except when specifically necessary, turn off the power of the controller while carrying out
maintenance. Lock the power switch, if necessary, so that no other person can turn it on.
(3) If it becomes necessary to enter the robot operation range while the power is on, press the
emergency stop button on the operator panel, or the teach pendant before entering the range. The
maintenance personnel must indicate that maintenance work is in progress and be careful not to
allow other people to operate the robot carelessly.
(4) When disconnecting the pneumatic system, be sure to reduce the supply pressure.
(5) Before the start of teaching, check that the robot and its peripheral devices are all in the normal
operating condition.
(6) Do not operate the robot in the automatic mode while anybody is in the robot work area.
(7) When you maintain the robot alongside a wall or instrument, or when multiple workers are working
nearby, make certain that their escape path is not obstructed.
(8) When a tool is mounted on the robot, or when any moving device other than the robot is installed,
such as belt conveyor, pay careful attention to its motion.
(9) If necessary, have a worker who is familiar with the robot system stand beside the operator panel
and observe the work being performed. If any danger arises, the worker should be ready to press
the EMERGENCY STOP button at any time.
(10) When replacing or reinstalling components, take care to prevent foreign matter from entering the
system.
(11) When handling each unit or printed circuit board in the controller during inspection, turn off the
circuit breaker to protect against electric shock.
If there are two cabinets, turn off the both circuit breaker.
(12) When replacing parts, be sure to use those specified by FANUC.
In particular, never use fuses or other parts of non-specified ratings. They may cause a fire or
result in damage to the components in the controller.
(13) When restarting the robot system after completing maintenance work, make sure in advance that
there is no person in the work area and that the robot and the peripheral devices are not abnormal.

3.1

SAFETY OF THE TOOLS AND
PERIPHERAL DEVICES
PRECAUTIONS IN PROGRAMMING

(1) Use a limit switch or other sensor to detect a dangerous condition and, if necessary, design the
program to stop the robot when the sensor signal is received.
(2) Design the program to stop the robot when an abnormal condition occurs in any other robots or
peripheral devices, even though the robot itself is normal.
(3) For a system in which the robot and its peripheral devices are in synchronous motion, particular care
must be taken in programming so that they do not interfere with each other.
(4) Provide a suitable interface between the robot and its peripheral devices so that the robot can detect
the states of all devices in the system and can be stopped according to the states.

PRECAUTIONS FOR MECHANISM

(1) Keep the component cells of the robot system clean, and operate the robot in an environment free of
grease, water, and dust.
(2) Don’t use unconfirmed liquid for cutting fluid and cleaning fluid.
(3) Employ a limit switch or mechanical stopper to limit the robot motion so that the robot or cable does
not strike against its peripheral devices or tools.
(4) Observe the following precautions about the mechanical unit cables. When theses attentions are not
kept, unexpected troubles might occur.
•
Use mechanical unit cable that have required user interface.
•
Don’t add user cable or hose to inside of mechanical unit.
•
Please do not obstruct the movement of the mechanical unit cable when cables are added to
outside of mechanical unit.
•
In the case of the model that a cable is exposed, Please do not perform remodeling (Adding a
protective cover and fix an outside cable more) obstructing the behavior of the outcrop of the
cable.
•
Please do not interfere with the other parts of mechanical unit when install equipments in the
robot.
(5) The frequent power-off stop for the robot during operation causes the trouble of the robot. Please
avoid the system construction that power-off stop would be operated routinely. (Refer to bad case
example.) Please execute power-off stop after reducing the speed of the robot and stopping it by
hold stop or cycle stop when it is not urgent. (Please refer to "STOP TYPE OF ROBOT" in
SAFETY for detail of stop type.)
(Bad case example)
•
Whenever poor product is generated, a line stops by emergency stop.
•
When alteration was necessary, safety switch is operated by opening safety fence and
power-off stop is executed for the robot during operation.
•
An operator pushes the emergency stop button frequently, and a line stops.
•
An area sensor or a mat switch connected to safety signal operate routinely and power-off stop
is executed for the robot.
(6) Robot stops urgently when collision detection alarm (SV050) etc. occurs. The frequent urgent stop
by alarm causes the trouble of the robot, too. So remove the causes of the alarm.

SAFETY OF THE ROBOT MECHANISM

4.1

PRECAUTIONS IN OPERATION

(1) When operating the robot in the jog mode, set it at an appropriate speed so that the operator can
manage the robot in any eventuality.
(2) Before pressing the jog key, be sure you know in advance what motion the robot will perform in the
jog mode.

4.2

PRECAUTIONS IN PROGRAMMING

(1) When the work areas of robots overlap, make certain that the motions of the robots do not interfere
with each other.

Controlled stop is different from Power-Off stop as follows:
In Controlled stop, the robot is stopped on the program path. This function is effective for a system
where the robot can interfere with other devices if it deviates from the program path.
In Controlled stop, physical impact is less than Power-Off stop. This function is effective for
systems where the physical impact to the mechanical unit or EOAT (End Of Arm Tool) should be
minimized.
The stopping distance and stopping time of Controlled stop is longer than the stopping distance and
stopping time of Power-Off stop, depending on the robot model and axis. Please refer the operator's
manual of a particular robot model for the data of stopping distance and stopping time.
This function is available only in CE or RIA type hardware.
When this option is loaded, this function can not be disabled.
The stop type of DCS Position and Speed Check functions is not affected by the loading of this option.

CAUTION
This error can be caused by the optional brake release unit if the on/off switch is
left in on position while the operator attempts to jog the robot. To recover, turn
the brake release unit off and cycle the controller power.
(11) SRVO-021 SRDY off (Group: i Axis: j)
(Explanation) The HRDY is on and the SRDY is off, although there is no other cause of an alarm.
(HRDY is a signal with which the host detects the servo system whether to turn on
or off the servo amplifier magnetic contactor. SRDY is a signal with which the
servo system informs the host whether the magnetic contactor is turned on.)
If the servo amplifier magnetic contactor cannot be turned on when directed so, it
is most likely that a servo amplifier alarm has occurred. If a servo amplifier
alarm has been detected, the host will not issue this alarm (SRDY off). Therefore,
this alarm indicates that the magnetic contactor cannot be turned on for an
unknown reason.
(Action 1)
Make sure that the E-stop board connectors CRMA43, CRMA31 and servo
amplifier SRMA43 are securely attached to the servo amplifier.
(Action 2)
It is possible that an instant disconnection of power source causes this alarm.

amplifier.
(Action 3)
Check the continuity of the robot connection cable and the internal robot power
cable.
(Action 4)
Check to see if the load is greater than the rating. If greater, reduce it to within the
rating. (If the load is too great, the torque required for acceleration / deceleration
becomes higher than the capacity of the motor.
As a result, the motor becomes unable to follow the command, and an alarm is
issued.)
(Action 5)
Check the input voltage to the controller is within the rated voltage and no phase is
lack. In addition, check the setting of the transformer is correct.
Check each phase voltage of the CRR38A connector of the three-phase power
(200 VAC) input to the servo amplifier. If it is 210 VAC or lower, check the line
voltage. (If the voltage input to the servo amplifier becomes low, the torque output
also becomes low. As a result, the motor may become unable to follow the
command, hence possibly causing an alarm.).

(22) SRVO-042 MCAL alarm (Group: i Axis: j)
(Explanation)
This alarm means that the contacts of the magnetic contactor have stuck to each
other. The alarm condition occurs if the magnetic contactor turns out to be already
on when an attempt is made to turn it on. The alarm condition is detected between
the time contact sticking occurs and the time an attempt is made to turn on the
magnetic contactor.
(Action 1)
Replace the E-stop unit.
(Action 2)
Replace the servo amplifier.
(23) SRVO-043 DCAL alarm (Group: i Axis: j)
(Explanation)
The regenerative discharge energy was too high to be dissipated as heat. (To run
the robot, the servo amplifier supplies energy to the robot. When going down the
vertical axis, the robot operates from the potential energy. If a reduction in the
potential energy is higher than the energy needed for acceleration, the servo
amplifier receives energy from the motor. A similar phenomenon occurs even
when no gravity is applied, for example, at deceleration on a horizontal axis. The
energy that the servo amplifier receives from the motor is called the regenerative
energy. The servo amplifier dissipates this energy as heat. If the regenerative
energy is higher than the energy dissipated as heat, the difference is stored in the
servo amplifier, causing an alarm.)
(Action 1)
This alarm may occur if the axis is subjected to frequent acceleration/deceleration
or if the axis is vertical and generates a large amount of regenerative energy.
If this alarm has occurred, relax the service conditions.
(Action 2)
Check fuse FS3 in the servo amplifier. If it has blown, remove the cause, and
replace the fuse. One of the probable causes of a blown fuse is a ground fault in
the servo amplifier for the auxiliary axis.
(Action 3)
The ambient temperature is excessively high. Or the regenerative resistor can't be
cooled effectively. Check the fan unit, and replace it if it stops. Clean up the fun
unit, the regenerative resistor and the louver if they are dirty.
(Action 4)
Make sure that the phase-to-phase voltages of input power fall within the specified
range by measurement. If the voltages are out of the range, inspect the power
equipment. When no failure is found, replace the E-stop unit.
(Action 5)
Make sure that the servo amplifier CRR63A and CRR63B connectors are
connected tightly. Then detach the cable from CRR63A and CRR63B connectors
on the Servo amplifier, and check for continuity between pins 1 and 2 of the
cable-end connector. If there is no continuity between the pins, replace the
regenerative resistor.
(Action 6)
Make sure that the servo amplifier CRR45A and CRR45B are connected tightly,
then detach the cables from CRR45A and CRR45B on the servo amplifier and
check the resistance between pins 1 and 2 of each cable end connector. If the
resistance is not 9Ω, replace the regenerative resistor. CRR45B may not be used
depending on the robot model.
(Action 7)
Replace the servo amplifier.

(Action 1)
Check the three-phase input voltage at the servo amplifier. If it is 230 VAC or
higher, check the line voltage. (If the three-phase input voltage is higher than

- Purpose of each alarm
1)

HC alarm (high current alarm)
If high current flow in a power transistor momentarily due to abnormality or noise in the control
circuit, the power transistor and rectifier diodes might be damaged, or the magnet of the motor might
be degaussed. The HC alarm is intended to prevent such failures.
OVC and OHAL alarms (overcurrent and overload alarms)
The OVC and OHAL alarms are intended to prevent overheat that may lead to the burnout of the
motor winding, the breakdown of the servo amplifier transistor, and the separate regenerative
resistor.
The OHAL alarm occurs when each built-in thermal relay detects a temperature higher than the rated
value. However, this method is not necessarily perfect to prevent these failures. For example, if
the motor frequently repeats to start and stop, the thermal time constant of the motor, which has a
large mass, becomes higher than the time constant of the thermal relay, because these two
components are different in material, structure, and dimension. Therefore, if the motor continues to
start and stop within a short time as shown in Fig. 3.5 (n), the temperature rise in the motor is steeper
than that in the thermal relay, thus causing the motor to burn before the thermal relay detects an
abnormally high temperature.

To prevent the above defects, software is used to monitor the current in the motor constantly in order to
estimate the temperature of the motor. The OVC alarm is issued based on this estimated temperature.
This method estimates the motor temperature with substantial accuracy, so it can prevent the failures
described above.

MAINTENANCE

B-82725EN-1/07

REPLACING A UNIT

This section explains how to replace each unit in the control section.

WARNING
1 Before you start to replace a unit, turn off the control unit main power. Also, keep
all machines in the area of the control unit switched. Otherwise, you could injure
personnel or damage equipment.
2 Before replacing components, read the maintenance manual to understand the
replacement procedure. Performing an incorrect replacement procedure can
lead to an unpredictable accident, resulting in breakage in the robot or personal
injury.
3 When a heavy component or unit is to be handled, support the workers with a
crane or the like not to apply excessive loads to the workers. Note that
incorrect handling can cause serious injury to the workers.
CAUTION
Components in the control unit heat up, so care should be taken. When you
have to touch a heated component, prepare a protector such as heat-resistant
gloves.

7.1

REPLACING THE PRINTED-CIRCUIT BOARDS
CAUTION
When you replace printed-circuit boards, observe the following cautions:
1 Keep the controller power switched off.
2 When you remove a printed-circuit board, do not touch the semiconductor
devices on the board with your hand or make them touch other components.
3 Make sure that the replacement printed-circuit board has been set up
appropriately. (Setting plug etc.)
4 After replacing a printed-circuit board, make adjustments correctly if the board
needs to be adjusted.
5 If the backplane board, power supply unit, or main board (including cards and
modules) is replaced, it is likely that robot parameters and taught data are
lost. Before you start to replace these components, save a backup copy of the
robot parameters and taught data to an external memory device.
6 Before you disconnect a cable, note its location. If a cable is detached for
replacement, reconnect it exactly as before.

7.1.1

Replacing the Backplane Board (Unit)

Replace the backplane board together with the plastic case.
(1) Remove the two screws fastening the case. (When cables are connected to option boards, detach
the cables.)
(2) Release the latches in the upper part on each side of the case from the base metal plate, and pull out
the case. The case can be pulled out with the backplane board, fan, and battery installed in the
case.

(1) Remove the screws
Fig.7.1.1 Replacing the backplane board

(3) Replace the backplane unit with a new one.
(4) Confirm that the screw and latch positions of the case are in place, and slowly set the case. When
the case is attached, the backplane board installed in the case is connected to the main board with the
connectors. When setting the case, check that the connectors are connected properly, and be
careful not to apply excessive force.
(5) After confirming that the case is surely latched, tighten the screws of the case. Lightly press the
fan and battery, and make sure that the connectors are connected securely. (If the cables of option
boards have been detached, connect the cables again.)

CAUTION
Be sure to back up all programs and a possibility of data loss when a backplanemounted printed circuit board is replaced.

7.1.2

Replacing the Main board

The backplane unit incorporates the backplane board, main board, and option boards.

CAUTION
Before starting replacement, turn off the main power of the controller. The main
board is equipped with battery-backed memory devices for holding robot
parameters and taught data. When the main board is replaced, the memory
contents are lost.
(1) Remove the case. (See Subsection 7.1.1.)
(2) Detach cables from the connectors on the main board, and remove the three screws fastening the
main board. The main board and fan board are connected directly with connector CA115A.
Detach the main board by sliding the main board downward.

REPLACING CARDS AND MODULES ON THE MAIN
BOARD
CAUTION
Before you start to replace a card or module, make a backup copy of robot
parameters and taught data. If the FROM/SRAM module is replaced, SRAM
memory contents are lost.

Demounting a Card
(1) Pull up the spacer metal fitting.
(2) A molded cover is attached to a corner of the servo card and CPU card although the shapes of the
covers attached to the cards differ from each other. Insert a finger into the rear of the cover and pull
up the cover slowly in the arrow direction shown in the figure below. (Note: At this time, hold the
neighborhood of the main board on the opposite side with the other hand whenever possible. A force
of 7 to 8 kgf is required for extraction. Be careful not to drop the card board due to the momentum of
extraction.)
(3) When one side of the card board is raised slightly by pulling up the cover, do not fully extract the
card board, but push back the cover softly.
(4) When the card board is pushed back to be parallel with the main board, pinch two sides of the card
board and pull up the card board. This completes the extraction of the card board.

REPLACING BATTERY

7.11.1

Battery for Memory Backup (3 VDC)

B-82725EN-1/07

The programs, and system variables are stored in the SRAM in the main board. The power to the
SRAM memory is backed up by a lithium battery mounted on the front panel of the main board. The
above data is not lost even when the main power of controller is turned off. A new battery can maintain
the contents of memory for about 4 years (Note).
When the voltage of the battery becomes low, the low-voltage battery alarm (system-035) is displayed on
the teach pendant. When this alarm is displayed, replace the battery as soon as possible. In general, the
battery can be replaced within one or two weeks, however, this depends on the system configuration.
If the battery voltage gets lower, it becomes impossible to back up the content of the SRAM. Cycling
power to the controller in this state causes system not to start, and LED located on the main board
displays "1" because the contents of memory have been lost. Clear the entire SRAM memory and
reenter data after replacing the battery. Important data should be saved to the memory card or other
external device beforehand in case of emergency.

NOTE
In a newly introduced robot, the battery is factory-installed. Battery replacement
may, therefore, be needed within 4 years after the introduction of the robot.

Replacing the lithium battery
(1)
(2)
(3)
(4)

Prepare a new lithium battery (ordering drawing number: A05B-2550-K030).
Turn the robot controller on for about 30 seconds.
Turn the robot controller off.
Pull out the battery unit located in the lower right part of the backplane unit. (Hold the latch of the
battery unit, unlatch the battery unit from the case, and pull out the unit.).

Hold this part and pull out the battery unit.

(5) Install a new battery unit. (Insert the battery unit until the latch of the unit snaps into the case.)
Check that the battery unit is latched securely.

Fig.7.11.1 Replacing the battery

CAUTION
Complete the steps (c) to (e) within 30 minutes.
If the battery is left disconnected for a long time, the contents of memory will be
lost.
To prevent possible data loss, it is recommended that the robot data such as
programs and system variables be backed up before battery replacement.
WARNING
Using other than the recommended battery may result in the battery explosion.
Replace the battery only with the specified battery (A05B-2550-K030).
Dispose of the replaced battery as an industrial waste, according to the laws and other rules in the country
where the controller is installed and those established by the municipality and other organizations that
have jurisdiction over the area where the controller is installed.

Description
Connect the contacts of the external emergency stop switch to these
terminals. When a contact is open, the servo power supply is turned off,
and the robot is immediately placed in the emergency stop state. When
using the contacts of a relay or contactor instead of the switch, connect a
spark killer to the coil of the relay or contactor, to suppress noise. When
these terminals are not used, jumper them.
These signals are used to stop the robot safely when the safety fence gate
is opened during operation in the AUTO mode. When a contact is open,
the robot decelerates then stops, and the servo power supply is turned off.
In the T1 or T2 mode and the DEADMAN switch is held correct position,
the robot can be operated even when the safety fence gate is open.
When using the contacts of a relay or contactor instead of the switch,
connect a spark killer to the coil of the relay or contactor, to suppress
noise. When these terminals are not used, jumper them.

NOTE
1 Use a contact which minimum load is 5 mA less.

Discrepancy in duplicate inputs results in an alarm.

Input timing of duplicate safety signals
Duplicate inputs are used for signals such as the external emergency stop signal, safety fence signal, and
servo off signal so that a response is made even when a single failure occurs. The statuses of these
duplicate input signals must always be changed at the same timing according to the timing specifications
provided in this section. The robot control unit always checks that the statuses of the duplicate inputs
are the same, and if the control unit finds a discrepancy, it issues an alarm. If the timing specifications
are not satisfied, an alarm may be issued because of a signal discrepancy.

DIGITAL I/O SIGNAL SPECIFICATIONS

This section describes the specifications of the digital I/O signals interfaced with the peripheral device,
end effector, and arc welder.

4.5.1

Peripheral Device Interface

(1) Output signals in peripheral device interface (Source type DO)
(a) Example of connection
Spark killer diode

0.2A or less

(b) Electrical specifications
Maximum load current when driver is on: 200 mA (including momentary level)
Saturation voltage when driver is on: 1.0 V max.
Dielectric strength: 24 V ±20% (including momentary level)
Leakage current when driver is off: 100 μA
(c) The external power supply to output signals must satisfy the following:
Power supply voltage: +24 V ±10%
Power supply current:
For each printed circuit board of this type
(Total sum of maximum load currents including momentary levels + 100 mA or more)
Power-on timing:
At the same time when the control unit is turned on or earlier
Power-off timing:
At the same time when the control unit is turned off or later
(d) Spark killer diode
Rated peak reverse voltage: 100 V or more
Rated effective forward current: 1 A or more
(e) Driver for output signals
In the driver device, the current of each output signal is monitored, and when an overcurrent is
detected, the relevant output is turned off. After an output has been turned off by overcurrent,
the overcurrent state is released because the output is off, so the output on state is restored.
Therefore, in the ground fault or overcurrent state, the output is turned on and off repeatedly.
Such a condition is found also when a load with a high surge current is connected.
The driver device also includes an overheat detection circuit, which turns off all outputs of the
device when the internal temperature of the device has increased as a result of a continued
overcurrent state due to a ground fault of an output and so on. The outputs are held off, but
their normal states can be restored by turning the power to the controller on and off after the
internal temperature of the device has lowered.
(f) Note on use
When adding a relay, solenoid, or the like directly to the circuit, connect a diode for counter
electromotive voltage protection in parallel to the load.

(c) Power supply to output signals
The +24 V power supply on the robot side can be used if the total current level, including the
current of the welding interface, is 0.7 A or less.
(d) Driver for output signals
In the driver device, the current of each output signal is monitored, and when an overcurrent is
detected, the relevant output is turned off. After an output has been turned off by overcurrent,

Ethernet Interface

This section describes information relating to the physical Ethernet connection.

CAUTION
1 Before connecting or disconnecting the cable to or from the FAST
Ethernet/FAST Data Server, make sure that the power to the CNC is turned off.
2 Please inquire of each manufacturer about the construction of network or the
condition of using the equipment except the FAST Ethernet/FAST Data Server
(hub, transceiver, cable etc.). When configuring your network, you must take
other sources of electrical noise into consideration to prevent your network from
being influenced by electrical noise. Make sure that network wiring is sufficiently
separated from power lines and other sources of electrical noise such as motors,
and ground each of the devices as necessary. Also, high and insufficient ground
impedance may cause interference during communications. After installing the
machine, conduct a communications test before you actually start operating the
machine.
We cannot ensure operation that is influenced by network trouble caused by a
device other than the FAST Ethernet or FAST Data Server.

4.8.2.1

Connection to Ethernet

The FAST Ethernet or FAST Data Server is provided with a 100BASE-TX interface.
Prepare a hub for connecting the FAST Ethernet board to the Ethernet trunk. The following shows an
example of a general connection.
Some devices (hub, transceiver, etc.) that are needed for building a network do not come in a dust-proof
construction. Using such devices in an atmosphere where they are subjected to dust or oil mist will
interfere with communications or damage the FAST Ethernet or FAST Data Server. Be sure to install
such devices in a dust-proof cabinet.

Leading out the Ethernet cable

For this type of control unit, the cable is drawn out only from the front of the control unit. See the
outline drawing of each type of board for the location of the connector.

Twisted-pair cable.
The radius of the cable
must be 70mm or less.

Clamp

Ground plate

The Ethernet cable must be fastened by a cable clamp to prevent tension being applied to the
modular connector (RJ-45) that connects the cable to the control unit even if the Ethernet cable is
pulled directly. This clamp is also used to ground the cable shield.

Electrical noise countermeasures

Clamping and Shielding Cables
Clamp an Ethernet twisted pair cable according to the method described below, as with cables that need
to be shielded. Clamping cables provides support and shielding and is extremely important to the safe
operation of the system. Never overlook cable clamping.
Peel off part of the jacket as shown in the figure to expose the outer coating of the shield, and press this outer
coating against the ground plate with the clamp fixture.
The machine manufacturer must prepare the ground plate and install it as follows:

Ground plate
Cable

Cable clamp
Ground plate

Shield
Peel off jacket

NOTE
To ensure the safe operation of the system, clamp and shield the cables.
Connect the Ethernet board and hub with a twisted-pair cable. Shield the cable with clamp fixtures.

Grounding the Network
Even if the grounding condition on the machine side is satisfied, the communication line can pick up
noise from the machine, depending on the machine installation condition and environment, thus resulting
in a communication error. To protect against such noise, the machine should be separated and insulated
from the Ethernet trunk cable and personal computer. Examples of connection are given below.

NOTE
1 The ground between PC/HUB side and machine system side must be separated.
If it is impossible to separate the ground because there is only one grounding
point, connect the ground cable for each system to the grounding point
independently. (See figure below.)
The resistance for grounding must be less than 100-ohm (Class D). The
thickness of the ground cable is the same as the thickness of AC power cable or
more. At least thickness of 5.5mm2 is necessary.
2 Note that the number of allowable hub-to-hub connections depends on the type
of hub.
3 There is possibility that noise makes the obstacle of communication even if the
ground is separated using the 100BASE-TX. In the case of using the FAST
Ethernet/FAST Data Server under the worst environment, please separate
between the PC/Trunk line side and machine system side completely using the
100BASE-FX (Optical fiber media).
