Workcell
Safety-3
• Install a lockout device that uses an access code 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.
• 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.
• Mount an adequate number of EMERGENCY STOP buttons or
switches within easy reach of the operator and at critical points inside and around the outside of the workcell.
• 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. Audible warning devices shall exceed the ambient noise level at the end–use application.
• 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.
Safety-4
• 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.
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 Robotics recommends that no one enter the work
envelope of a robot that is on, except for robot teaching
operations. However, if you must enter the work envelope, be
sure all safeguards are in place, check the teach pendant
DEADMAN switch for proper operation, and place the robot in
teach mode. 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.
Staying Safe While Teaching or Manually
Operating the Robot
Safety-5
WARNING
Never bypass, strap, or otherwise deactivate a safety device, such as a limit switch, for any operational convenience. Deactivating a safety device is known to have resulted in serious injury and death.
• 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.
Advise all personnel who operate the robot during production to
observe the following rules:
• Make sure all safety provisions are present and active.
• 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 automatic operation.
• Make sure all personnel are outside the work envelope before operating the robot.
Staying Safe During
Automatic Operation
Safety-6
• Never enter or allow others to enter the work envelope during automatic 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 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.
When inspecting the robot, be sure to
• Turn off power at the controller.

hard stop. Support the arm on a solid support before you release the brake.
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.
Safety-8
• 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 robot arm will fall if it is not supported or resting on a hard stop. Support the arm on a solid support before you
release the brake.
• 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.
• 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.
Certain programming and mechanical measures are useful in keeping the machine tools and other external devices safe. Some of these measures are outlined below. Make sure you know all associated measures for safe use of such devices.

NOTE Any deviation from the methods and safety practices
described in this manual must conform to the approved standards of
your company. If you have questions, see your supervisor.
Process technicians are sometimes required to enter the paint booth, for example, during daily or routine calibration or while teaching new paths to a robot. Maintenance personal also must
work inside the paint booth periodically.
Whenever personnel are working inside the paint booth, ventilation
equipment must be used. Instruction on the proper use of
ventilating equipment usually is provided by the paint shop
supervisor.
Although paint booth hazards have been minimized, potential
dangers still exist. Therefore, today’s highly automated paint booth
requires that process and maintenance personnel have full
awareness of the system and its capabilities. They must
understand the interaction that occurs between the vehicle moving
along the conveyor and the robot(s), hood/deck and door opening
devices, and high–voltage electrostatic tools.
Paint robots are operated in three modes:
• Teach or manual mode
• Automatic mode, including automatic and exercise operation
• Diagnostic mode
During both teach and automatic modes, the robots in the paint
booth will follow a predetermined pattern of movements. In teach
mode, the process technician teaches (programs) paint paths using
the teach pendant.
In automatic mode, robot operation is initiated at the System
Operator Console (SOC) or Manual Control Panel (MCP), if
available, and can be monitored from outside the paint booth. All
personnel must remain outside of the booth or in a designated safe

Safety-11
area within the booth whenever automatic mode is initiated at the
SOC or MCP.
In automatic mode, the robots will execute the path movements they
were taught during teach mode, but generally at production speeds.
When process and maintenance personnel run diagnostic routines
that require them to remain in the paint booth, they must stay in a
designated safe area.
Process technicians and maintenance personnel must become totally familiar with the equipment and its capabilities. To minimize the risk of injury when working near robots and related equipment,
personnel must comply strictly with the procedures in the manuals.
This section provides information about the safety features that are
included in the paint system and also explains the way the robot
interacts with other equipment in the system.
The paint system includes the following safety features:
• Most paint booths have red warning beacons that illuminate when the robots are armed and ready to paint. Your booth
might have other kinds of indicators. Learn what these are.
• Some paint booths have a blue beacon that, when illuminated, indicates that the electrostatic devices are enabled. Your booth might have other kinds of indicators. Learn what these are.
• EMERGENCY STOP buttons are located on the robot controller and teach pendant. Become familiar with the locations of all E–
STOP buttons.
• An intrinsically safe teach pendant is used when teaching in hazardous paint atmospheres.
• A DEADMAN switch is located on each teach pendant. When this
switch is held in, and the teach pendant is on, power is applied to the
robot servo system. If the engaged DEADMAN switch is released
during robot operation, power is removed from the servo system, all
axis brakes are applied, and the robot comes to an EMERGENCY
STOP. Safety interlocks within the system might also E–STOP other
robots.
WARNING
An EMERGENCY STOP will occur if the DEADMAN switch is
released on a bypassed robot.
Paint System Safety
Features
Safety-12
• Overtravel by robot axes is prevented by software limits. All of
the major and minor axes are governed by software limits. Limit switches and hardstops also limit travel by the major axes.
• EMERGENCY STOP limit switches and photoelectric eyes might be part of your system. Limit switches, located on the entrance/exit doors of each booth, will EMERGENCY STOP all
equipment in the booth if a door is opened while the system is operating in automatic or manual mode. For some systems,
signals to these switches are inactive when the switch on the SCC is in teach mode.
When present, photoelectric eyes are sometimes used to monitor unauthorized intrusion through the entrance/exit
silhouette openings.
• System status is monitored by computer. Severe conditions result in automatic system shutdown.
When you work in or near the paint booth, observe the following rules, in addition to all rules for safe operation that apply to all robot
systems.
WARNING
Observe all safety rules and guidelines to avoid injury.

Operator safety is the primary safety consideration. Because it is verydangerous to enter the operating space of the robot during automaticoperation, adequate safety precautions must be observed.The following lists the general safety precautions. Careful considerationmust be made to ensure operator safety.(1) Have the robot system operators attend the training courses held byFANUC.FANUC provides various training courses. Contact our sales office for details.
(2) Even when the robot is stationary, it is possible that the robot is stillready to move state and is waiting for a signal. In this state, the robotis regarded as still in motion. To ensure operator safety, provide thesystem with an alarm to indicate visually or aurally that the robot isin motion.(3) Install a safety fence with a gate so that no operator can enter the workarea without passing through the gate. Equip the gate with aninterlock that stops the robot when the gate is opened.The controller is designed to receive this interlock signal. When the gate isopened and this signal received, the controller stops the robot in an emergency.For connection, see Fig.1.1.
(4) Provide the peripheral devices with appropriate grounding (Class 1,Class 2, or Class 3).(5) Try to install the peripheral devices outside the work area.(6) Draw an outline on the floor, clearly indicating the range of the robotmotion, including the tools such as a hand.(7) Install a mat switch or photoelectric switch on the floor with aninterlock to a visual or aural alarm that stops the robot when anoperator enters the work area.(8) If necessary, install a safety lock so that no one except the operatorin charge can turn on the power of the robot.The circuit breaker installed in the controller is designed to disable anyone fromturning it on when it is locked with a padlock.

The operator is a person who operates the robot system. In this sense, aworker who operates the teach pendant is also an operator. However, thissection does not apply to teach pendant operators.(1) If it is not necessary for the robot to operate, turn off the power of therobot controller or press the EMERGENCY STOP button, and thenproceed with necessary work.(2) Operate the robot system at a location outside the work area.(3) Install a safety fence with a safety gate to prevent any worker otherthan the operator from entering the work area unexpectedly and alsoto 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 EMERGENCYSTOP button. With this connection, the controller stops the robot operationwhen the external EMERGENCY STOP button is pressed. See the diagrambelow for connection.

While teaching the robot, it is necessary for the operator to enter the workarea of the robot. It is particularly necessary to ensure the safety of theteach pendant operator.(1) Unless it is specifically necessary to enter the robot work area, carryout all tasks outside the area.(2) Before teaching the robot, check that the robot and its peripheraldevices are all in the normal operating condition.(3) When entering the robot work area and teaching the robot, be sure tocheck the location and condition of the safety devices (such as theEMERGENCY STOP button and the deadman switch on the teachpendant).FANUC’s teach pendant has a switch for enabling or disabling the robot opera-tion from the teach pendant and a deadman switch in addition to the EMER-GENCY STOP button. The switches function as follows.
EMERGENCY STOP button : Pressing this button always brings the robotto an emergency stop, irrespective of thestate of the enable/disable switch and themode switch of operator panel.
Deadman switch : The function of this switch depends on thestate of the enable/disable switch and themode switch of operator panel.
When the mode switch is in the AUTO position– The enable/disable switch and deadman
switch are disabled.
When the mode switch is in the TI position and the enable/disable switch isin the enable position
– Releasing the deadman switch brings therobot to an emergency stop.
When the mode switch is in the TI position and the enable/disable switch isin the disable position
– The robot is brought to an emergency stopregardless of the operation of the deadmanswitch.
Note)The deadman switch is provided to bring the robot to an emergencystop when the operator releases the teach pendant in an emergency.
(4) The teach pendant operator should pay careful attention so that noother workers enter the robot work area.NOTE
In addition to the above, the teach pendant enable switch and the
deadman switch also have the following function.
By pressing the deadman switch while the enable switch is on, the
emergency stop factor (normally the safety gate) connected to
FENCE11 and FENCE12 of the controller is invalidated. In this
case, it is possible for an operator to enter the fence during teach
operation without making the robot in the emergency stop
condition. In other words, the system understands that the
combined operations of pressing the teach pendant enable switch
and pressing the deadman switch indicates the start of teaching.
The teach pendant operator should be well aware that the safety gate
is not functional under this condition and bear full responsibility to
ensure that no one enters the fence during teaching.

(5) When entering the robot work area, the teach pendant operator shouldenable the teach pendant whenever he or she enters the robot workarea. In particular, while the teach pendant enable switch is off, makecertain that no start command is sent to the robot from any operatorpanel other than the teach pendant.The teach pendant, operator panel, and peripheral device interface send eachrobot start signal. However the validity of each signal changes as follows de-pending on the mode of the teach pendant enable switch and the mode switchthe remote switch on the operator panel.

For the safety of maintenance personnel, pay utmost attention to thefollowing.(1) Except when specifically necessary, turn off the power of thecontroller while carrying out maintenance. Lock the power switch,if necessary, so that no other person can turn it on.(2) When disconnecting the pneumatic system, be sure to reduce thesupply pressure.(3) Before the start of teaching, check that the robot and its peripheraldevices are all in the normal operating condition.(4) If it is necessary to enter the robot work area for maintenance whenthe power is turned on, the worker should indicate that the machineis being serviced and make certain that no one starts the robotunexpectedly.(5) Do not operate the robot in the automatic mode while anybody is inthe robot work area.(6) When it is necessary to maintain the robot alongside a wall orinstrument, or when multiple workers are working nearby, makecertain that their escape path is not obstructed.(7) When a tool is mounted on the robot, or when any moving deviceother than the robot is installed, such as belt conveyor, pay carefulattention to its motion.(8) If necessary, have a worker who is familiar with the robot systemstand beside the operator panel and observe the work beingperformed. If any danger arises, the worker should be ready to pressthe EMERGENCY STOP button at any time.(9) When replacing or reinstalling components, take care to preventforeign matter from entering the system.(10)When handling each unit or printed circuit board in the controllerduring inspection, turn off the power of the controller and also turnoff the circuit breaker to protect against electric shock.(11) 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 thecontroller.

Ifgreater, reduce it to within the rating. (If the load istoo greater, the torque required for acceleration /deceleration becomes higher than the capacity of themotor. As a result, the motor becomes unable tofollow the command, and an alarm is issued.)(Action 4) Check each phase voltage of the CZ1 connector of thethree–phase power (200 VAC) input to the servoamplifier. If it is 170 VAC or lower, check the linevoltage. (If the voltage input to the servo amplifierbecomes low, the torque output also becomes low. Asa result the motor may become unable to follow thecommand, hence possibly an alarm.)(Action 5) If the line voltage is 170 VAC or higher, replace thepower supply module or servo amplifier module.(Action 6) Check disconnection of robot connection cable(RMP).(Action 7) Replace the motor.

Relationships among the OVC, OVL, and HC alarmsOverviewThis section points out the differences among the OVC, OVL, and HCalarms and describes the purpose of each alarm.Alarm detection section
Abbreviation Designation Detection section
OVC Overcurrent alarm Servo software
OVL Overload alarm Thermal relay in the motor OHAL2Thermal relay in the servo amplifier OHAL1Thermal relay in the separate regenerative dis-charge unit DCAL
HC High current alarm Servo amplifier
Purpose of each alarm1) HC alarm (high current alarm)If high current flow in a power transistor momentarily due toabnormality or noise in the control circuit, the power transistor andrectifier diodes might be damaged, or the magnet of the motor mightbe degaussed. The HC alarm is intended to prevent such failures.2) OVC and OVL alarms (overcurrent and overload alarms)The OVC and OVL alarms are intended to prevent overheat that maylead to the burnout of the motor winding, the breakdown of the servoamplifier transistor, and the separate regenerative resistor.The OVL alarm occurs when each built–in thermal relay detects atemperature higher than the rated value. However, this method is notnecessarily perfect to prevent these failures. For example, if themotor frequently repeats to start and stop, the thermal time constantof the motor, which has a large mass, becomes higher than the timeconstant of the thermal relay, because these two components aredifferent in material, structure, and dimension. Therefore, if themotor repeats to start and stop within a short time as shown in Fig.1, the temperature rise in the motor is steeper than that in the thermalrelay, thus causing the motor to burn before the thermal relay detectsan abnormally high temperature.

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

(To move the robot, the servoamplifier supplies energy to the robot. When goingdown, the robot moves along the vertical axis as thepotential energy reduces. If a reduction in thepotential energy is larger than the amount ofacceleration energy, the servo amplifier receivesenergy from the motor. This also occurs atdeceleration even when no gravity is applied. Theenergy that the servo amplifier receives from themotor is called regenerative energy. The servoamplifier dissipates this energy as heat. If the amountof the regenerative energy dissipated as heat issmaller than was received, the remainder is stored inthe servo amplifier, causing this alarm.) The LEDindication on the power supply module is “8”(DCAL: regenerative energy adder detection).(Action 1) This alarm may occur if the robot is subjected tofrequent acceleration/deceleration or if the verticalaxis generates a large amount of regenerative energy.In this case, relax the service conditions.(Action 2) Replace the power supply module.

The programs, and system variables are stored in the SRAM in the Robotcontrol board. The power to the SRAM memory is backed up by a lithiumbattery mounted on the front panel of the Robot control board. The abovedata is not lost even when the main battery goes dead. A new battery canmaintain the contents of memory for about 4 years (Note).When the voltage of the battery becomes low, the battery alarm LED onthe operator panel is lit, and the low–voltage battery alarm (system–035)is displayed on the teach pendant. When this alarm is displayed, replacethe battery as soon as possible. In general, the battery can be replacedwithin one or two weeks, however, this depends on the systemconfiguration.If the battery voltage gets lower, it becomes impossible to back up thecontent of the SRAM. Turning on the power to the in this state causessystem not to start and LED of seven segment on the Robot control boardto be displayed “1” because the contents of memory are lost. Clear theentire SRAM memory and reenter data after replacing the battery.Important data should be saved to the memory card or floppy diskbeforehand in case of emergency.When replacing the memory backup battery, do so while the robotcontroller is turned off in case of emergency.NOTE
In a newly introduced robot, the battery is factory–installed.Battery replacement may, therefore, be needed within 4years after the introduction of the robot.
(1)Prepare a new lithium battery (ordering drawing number:A02B–0200–K102).(2)Turn the robot controller on for about 30 seconds.(3)Turn the robot controller off.(4)Remove the old battery from the top of the Robot control board.First unlatch the battery, remove it from the battery holder, and detachits connector.

CAUTIONComplete the steps (3) to (5) 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

BPERIPHERAL INTERFACE
Peripheral I/O (UI/UO) are a group of specialized signals whose usage isdecided by the system. These signals are connected with a remotecontroller and the peripheral devices via the following interfaces and I/Olinks and they are used to control the robot from the outside. The JD1A interface (The process I/O board, the I/O Unit MODEL Aand the MODEL B are connected as the slave of I/O link to R–J3iBMate.) (on master mode) The JD1B interface (CNC and PLC are connected as a master of I/Olink to R–J3iB Mate.) (on slave mode) CRM9 interfaceRefer to the operator’s MANUAL for detail informations.

Fellowing is each input signal.
The remote controller uses the hold signal to halt the robot. Because*HOLD input signal is a inverted signal, normally set the signal on. Whenthe signal goes off, the following is executed: The robot is decelerated until its stops, then the program execution ishalted. If ENABLED is specified at “Break on hold” on the general itemsetting screen, the robot is stopped, an alarm is generated, and theservo power is turned off. (Standard setting: DISABLED)The RESET signal cancels an alarm. If the servo power is off, the RESETsignal turns on the servo power. The alarm output is not canceled until theservo power is turned on. The alarm is canceled at the instant this signalfalls in default setting. If TRUE is specified at “CSTOPI for ABORT” on the systemconfiguration screen, the RESET signal resets an alarm and aborts thecurrently selected program. (Standard setting: FALSE) To have alarms reset the instant the RESET signal rises, it is necessaryto specify RISE at “Detect FAULT RESET signal” on the systemconfiguration screen. (Standard setting: FALL)The START signal has two functions. It can select or collate a programand start the program. When the START signal goes high, PNS1 to PNS4 are read and thecorresponding program is selected or collated. Whether is program isselected or collated is specified by the setting of system variable$SHELL_CFG.$NUM_RSR [1]. (See the description of signalsPNS1 to PNS4.) When the START signal goes low, the current program is started fromthe line at which the cursor is placed (current line). If TRUE is specified at “START for CONTINUE only” on the systemconfiguration screen, only a program on hold can be started. (Standardsetting: FALSE)The ENBL signal allows the robot to be moved and places the robot in theready state. When the ENBL signal is off, the system inhibits a jog feedof the robot and activation of a program including a motion (group). Aprogram which is being executed is halted when the ENBL signal is setoff.NOTE
When the ENBL signal is not monitored, strap the signalwith the ground.

A program number selection signal has two functions.When the START signal goes on, PNS1 to PNS4 are read and thecorresponding program is selected or collated. Whether the program isselected or collated is specified by the setting of system variable$SHELL_CFG.$NUM_RSR [1]. In the program end state, a program is selected or collated accordingto the state (0 or 1) of the PNS signals. The current line of the selectedor collated program is set to 1.
Type 1 (when $SHELL_CFG.$NUM_RSR [1] is set to 0)The program specified by the PNS signals is selected. Type 2 (when $SHELL_CFG.$NUM_RSR [1] is set to 1)The program specified by the PNS signals is collated with thecurrent program. If the programs do not agree with each other, anerror occurs.
If all PNS signals are low in the program end state, the current programis executed from the current line. If no programs are selected, an erroroccurs. A halted program can be resumed only when all PNS signals are setoff. Otherwise, an error occurs. While a program is being executed, the PNS signals are ignored.
Fellowing are peripheral device interface output signals.
The CMDENBL signal is output when the following conditions aresatisfied. The CMDENBL signal indicates that the remote controller canstart a program including a motion (group). The remote conditions are satisfied. The ready conditions are satisfied. The continuous operation mode is selected (the single step mode isdisabled).The FAULT signal is output when an alarm occurs in the system. TheRESET signal cancels the alarm. If a warning (WARN alarm) occurs, theFAULT signal is not output.The BATALM signal indicates that the voltage of the battery forsupporting the memory has dropped. Replace the battery while keepingthe power of the controller on.To have the BATALM signal generated also when the BZAL/BLAL alarmoccurs, it is necessary to set the $BLAL_OUT.$BATALM_OR systemvariable. It is also possible to have the specified SDO output when theBZAL/BLAL alarm occurs.The BUSY signal is output while a program is being executed. The BUSYsignal is not output while a program is being halted.

(1) RDI/RDOThese are signals sent to the connector at the wrist of the robot.They cannot be assigned (redefined) and are fixed.The standard format is six inputs and six outputs. The number ofpoints that can be used for the connector at the wrist depends on theindividual robot.(2) SDI/SDOThe signal No. that is determined at hardware can be changed bysoftware operation.(3) Analog I/OAn analog I/O signal can access the analog I/O port (optional) on theprocess I/O printed circuit board or the I/O port on the analog I/Omodule (used together with the I/O unit model A).It reads and writes the digital value converted from the analog valueof the I/O voltage. It means that the value does not always representthe real I/O voltage.(4) Group I/OGroup I/O is a function which can input or output multiple DI/DOsignals as binary codes.Any number of continuous signals of up to 16 bits can be set for itsuse.It can be set in the menu DETAILS on the group I/O screen.
