SAFETY B62163EN/03s2

Safety is essential whenever robots are used. Keep in mind the followingfactors 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

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 thefollowing:

People External devices Robot(s) Tooling Workpiece

Always give appropriate attention to the work area that surrounds therobot. The safety of the work area can be enhanced by the installation ofsome 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

A safe workcell is essential to protect people and equipment. Observe thefollowing guidelines to ensure that the workcell is set up safely. Thesesuggestions 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 Roboticstraining course(s) related to your application. Never permit untrainedpersonnel to operate the robots.

Install a lockout device that uses an access code to preventunauthorized persons from operating the robot.

Use anti-tie-down logic to prevent the operator from bypassing safetymeasures.

Arrange the workcell so the operator faces the workcell and can seewhat is going on inside the cell.

CONSIDERINGSAFETY FOR YOURROBOTINSTALLATION

Keeping People andEquipment Safe

Using SafetyEnhancing Devices

Setting Up a SafeWorkcell

SAFETYB62163EN/03 s3

Clearly identify the work envelope of each robot in the system withfloor markings, signs, and special barriers. The work envelope is thearea defined by the maximum motion range of the robot, including anytooling 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 orswitches within easy reach of the operator and at critical points insideand around the outside of the workcell.

Install flashing lights and/or audible warning devices that activatewhenever the robot is operating, that is, whenever power is applied tothe servo drive system.

Wherever possible, install safety fences to protect against unauthorizedentry by personnel into the work envelope.

Install special guarding that prevents the operator from reaching intorestricted 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 beoptionally installed between the robot wrist flange and tooling. If thetooling strikes an object, these devices dislodge, remove power fromthe 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 theeffects of electro-magnetic interference (EMI), radio frequencyinterference (RFI), and electro-static discharge (ESD).

Make provisions for power lockout/tagout at the controller.

Eliminate pinch points. Pinch points are areas where personnel couldget trapped between a moving robot and other equipment.

Provide enough room inside the workcell to permit personnel to teachthe robot and perform maintenance safely.

Program the robot to load and unload material safely.

If high voltage electrostatics are present, be sure to provide appropriateinterlocks, warning, and beacons.

If materials are being applied at dangerously high pressure, provideelectrical interlocks for lockout of material flow and pressure.


Advise all personnel who must teach the robot or otherwise manuallyoperate the robot to observe the following rules:

Never wear watches, rings, neckties, scarves, or loose clothing thatcould get caught in moving machinery.

Know whether or not you are using an intrinsically safe teach pendantif you are working in a hazardous environment.

Before teaching, visually inspect the robot and work envelope to makesure that no potentially hazardous conditions exist. The workenvelope is the area defined by the maximum motion range of therobot. These include tooling attached to the wrist flange that extendsthis range.

The area near the robot must be clean and free of oil, water, or debris.Immediately report unsafe working conditions to the supervisor orsafety department.

FANUC Robotics recommends that no one enter the work envelope ofa robot that is on, except for robot teaching operations. However, ifyou must enter the work envelope, be sure all safeguards are in place,check the teach pendant DEADMAN switch for proper operation, andplace the robot in teach mode. Take the teach pendant with you, turn iton, and be prepared to release the DEADMAN switch. Only theperson with the teach pendant should be in the work envelope.

WARNINGNever 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 inserious injury and death.

Know the path that can be used to escape from a moving robot; makesure the escape path is never blocked.

Isolate the robot from all remote control signals that can cause motionwhile data is being taught.

Test any program being run for the first time in the following manner:

WARNINGStay outside the robot work envelope whenever a programis being run. Failure to do so can result in injury.

Using a low motion speed, single step the program for at least onefull cycle.

Using a low motion speed, test run the program continuously forat least one full cycle.

Using the programmed speed, test run the program continuouslyfor at least one full cycle.

Make sure all personnel are outside the work envelope before runningproduction.

Staying Safe WhileTeaching or ManuallyOperating the Robot


Advise all personnel who operate the robot during production to observethe following rules:

Make sure all safety provisions are present and active.

Know the entire workcell area. The workcell includes the robot and itswork envelope, plus the area occupied by all external devices andother equipment with which the robot interacts.

Understand the complete task the robot is programmed to performbefore initiating automatic operation.

Make sure all personnel are outside the work envelope beforeoperating the robot.

Never enter or allow others to enter the work envelope duringautomatic operation of the robot.

Know the location and status of all switches, sensors, and controlsignals that could cause the robot to move.

Know where the EMERGENCY STOP buttons are located on both therobot control and external control devices. Be prepared to press thesebuttons 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 tocontinue activity.

If the robot is running in a pattern, do not assume it will continue torun in the same pattern.

Never try to stop the robot, or break its motion, with your body. Theonly way to stop robot motion immediately is to press anEMERGENCY STOP button located on the controller panel, teachpendant, or emergency stop stations around the workcell.

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 tothe 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.


Staying Safe DuringAutomatic Operation

Staying Safe DuringInspection


If power is needed to check the robot motion or electrical circuits, beprepared to press the EMERGENCY STOP button, in an emergency.

Be aware that when you remove a servomotor or brake, the associatedrobot 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 performing maintenance on your robot system, observe the following rules:

Never enter the work envelope while the robot or a program is inoperation.

Before entering the work envelope, visually inspect the workcell tomake sure no potentially hazardous conditions exist.


Consider all or any overlapping work envelopes of adjoining robotswhen standing in a work envelope.

Test the teach pendant for proper operation before entering the workenvelope.

If it is necessary for you to enter the robot work envelope while poweris turned on, you must be sure that you are in control of the robot. Besure to take the teach pendant with you, press the DEADMAN switch,and turn the teach pendant on. Be prepared to release the DEADMANswitch 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.


WARNINGLethal voltage is present in the controller WHENEVER IT ISCONNECTED to a power source. Be extremely careful toavoid electrical shock.

HIGH VOLTAGE IS PRESENT at the input side wheneverthe controller is connected to a power source. Turning thedisconnect or circuit breaker to the OFF position removespower from the output side of the device only.

Release or block all stored energy. Before working on the pneumaticsystem, shut off the system air supply and purge the air lines.

Staying Safe DuringMaintenance


Isolate the robot from all remote control signals. If maintenance mustbe done when the power is on, make sure the person inside the workenvelope has sole control of the robot. The teach pendant must beheld by this person.

Make sure personnel cannot get trapped between the moving robot andother equipment. Know the path that can be used to escape from amoving robot. Make sure the escape route is never blocked.

Use blocks, mechanical stops, and pins to prevent hazardousmovement by the robot. Make sure that such devices do not createpinch points that could trap personnel.

WARNINGDo not try to remove any mechanical component from therobot before thoroughly reading and understanding theprocedures in the appropriate manual. Doing so can resultin serious personal injury and component destruction.


When replacing or installing components, make sure dirt and debris donot enter the system.

Use only specified parts for replacement. To avoid fires and damageto parts in the controller, never use nonspecified fuses.

Before restarting a robot, make sure no one is inside the workenvelope; be sure that the robot and all external devices are operatingnormally.


Certain programming and mechanical measures are useful in keeping themachine tools and other external devices safe. Some of these measures areoutlined below. Make sure you know all associated measures for safe useof such devices.

Implement the following programming safety measures to prevent damageto machine tools and other external devices.

Back-check limit switches in the workcell to make sure they do notfail.

Implement failure routines in programs that will provide appropriaterobot actions if an external device or another robot in the workcellfails.

Use handshaking protocol to synchronize robot and external deviceoperations.

Program the robot to check the condition of all external devices duringan operating cycle.

Implement the following mechanical safety measures to prevent damage tomachine tools and other external devices.

Make sure the workcell is clean and free of oil, water, and debris.

Use software limits, limit switches, and mechanical hardstops toprevent undesired movement of the robot into the work area ofmachine tools and external devices.

KEEPING THEROBOT SAFE

Operating SafetyPrecautions

Programming SafetyPrecautions


Process technicians are sometimes required to enter the paint booth, forexample, during daily or routine calibration or while teaching new paths toa robot. Maintenance personnel also must work inside the paint boothperiodically.

Whenever personnel are working inside the paint booth, ventilationequipment must be used. Instruction on the proper use of ventilatingequipment usually is provided by the paint shop supervisor.

Although paint booth hazards have been minimized, potential dangers stillexist. Therefore, todays highly automated paint booth requires thatprocess and maintenance personnel have full awareness of the system andits capabilities. They must understand the interaction that occurs betweenthe vehicle moving along the conveyor and the robot(s), hood/deck anddoor 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 willfollow a predetermined pattern of movements. In teach mode, the processtechnician teaches (programs) paint paths using the teach pendant.

In automatic mode, robot operation is initiated at the System OperatorConsole (SOC) or Manual Control Panel (MCP), if available, and can bemonitored from outside the paint booth. All personnel must remainoutside of the booth or in a designated safe area within the booth wheneverautomatic mode is initiated at the SOC or MCP.

In automatic mode, the robots will execute the path movements they weretaught during teach mode, but generally at production speeds.

When process and maintenance personnel run diagnostic routines thatrequire them to remain in the paint booth, they must stay in a designatedsafe area.

ADDITIONALSAFETYCONSIDERATIONSFOR PAINT ROBOTINSTALLATIONS


Process technicians and maintenance personnel must become totallyfamiliar with the equipment and its capabilities. To minimize the risk ofinjury when working near robots and related equipment, personnel mustcomply strictly with the procedures in the manuals.

This section provides information about the safety features that areincluded in the paint system and also explains the way the robot interactswith other equipment in the system.

The paint system includes the following safety features:

Most paint booths have red warning beacons that illuminate when therobots are armed and ready to paint. Your booth might have otherkinds 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 mighthave other kinds of indicators. Learn what these are.

EMERGENCY STOP buttons are located on the robot controller andteach pendant. Become familiar with the locations of all E-STOPbuttons.

An intrinsically safe teach pendant is used when teaching in hazardouspaint atmospheres.

A DEADMAN switch is located on each teach pendant. When thisswitch is held in, and the teach pendant is on, power is applied to therobot servo system. If the engaged DEADMAN switch is releasedduring robot operation, power is removed from the servo system, allaxis brakes are applied, and the robot comes to an EMERGENCYSTOP. Safety interlocks within the system might also E-STOP otherrobots.

WARNINGAn EMERGENCY STOP will occur if the DEADMAN switchis released on a bypassed robot.

Overtravel by robot axes is prevented by software limits. All of themajor and minor axes are governed by software limits. Limit switchesand hardstops also limit travel by the major axes.

Paint System SafetyFeatures


EMERGENCY STOP limit switches and photoelectric eyes might bepart of your system. Limit switches, located on the entrance/exit doorsof each booth, will EMERGENCY STOP all equipment in the booth ifa door is opened while the system is operating in automatic or manualmode. For some systems, signals to these switches are inactive whenthe switch on the SCC is in teach mode.

When present, photoelectric eyes are sometimes used to monitorunauthorized intrusion through the entrance/exit silhouette openings.

System status is monitored by computer. Severe conditions result inautomatic system shutdown.

When you work in or near the paint booth, observe the following rules, inaddition to all rules for safe operation that apply to all robot systems.

WARNINGObserve all safety rules and guidelines to avoid injury.

WARNINGNever 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 inserious injury and death.

Know the work area of the entire paint station (workcell).

Know the work envelope of the robot and hood/deck and door openingdevices.

Be aware of overlapping work envelopes of adjacent robots.

Know where all red, mushroom-shaped EMERGENCY STOP buttonsare located.

Know the location and status of all switches, sensors, and/or controlsignals that might cause the robot, conveyor, and opening devices tomove.

Make sure that the work area near the robot is clean and free of water,oil, and debris. Report unsafe conditions to your supervisor.

Become familiar with the complete task the robot will performBEFORE starting automatic mode.

Make sure all personnel are outside the paint booth before you turn onpower to the robot servo system.

Staying Safe WhileOperating the PaintRobot


Never enter the work envelope or paint booth before you turn offpower to the robot servo system.

Never enter the work envelope during automatic operation unless asafe area has been designated.


Remove all metallic objects, such as rings, watches, and belts, beforeentering a booth when the electrostatic devices are enabled.

Stay out of areas where you might get trapped between a movingrobot, conveyor, or opening device and another object.

Be aware of signals and/or operations that could result in the triggeringof guns or bells.

Be aware of all safety precautions when dispensing of paint isrequired.

Follow the procedures described in this manual.

When you perform maintenance on the painter system, observe thefollowing rules, and all other maintenance safety rules that apply to allrobot installations. Only qualified, trained service or maintenancepersonnel should perform repair work on a robot.

Paint robots operate in a potentially explosive environment. Usecaution when working with electric tools.

When a maintenance technician is repairing or adjusting a robot, thework area is under the control of that technician. All personnel notparticipating in the maintenance must stay out of the area.

For some maintenance procedures, station a second person at thecontrol panel within reach of the EMERGENCY STOP button. Thisperson must understand the robot and associated potential hazards.

Be sure all covers and inspection plates are in good repair and in place.

Always return the robot to the home position before you disarm it.

Never use machine power to aid in removing any component from therobot.

During robot operations, be aware of the robots movements. Excessvibration, unusual sounds, and so forth, can alert you to potentialproblems.

Whenever possible, turn off the main electrical disconnect before youclean the robot.

Each unit of I/O UnitB must be properly grounded. This is particularlyimportant for the reasons listed below.

A low resistance path from all parts of a system to earth minimizesexposure to shock in the event of short circuits or equipmentmalfunction.

I/O UnitB requires proper grounding in order to operate correctly.

If ground wire is needed, ground wire should be as short and as large aspossible. Braided straps or ground cables can be used to minimizeresistance. Conductors must always be large enough to carry themaximum short circuit current of the path being considered. (Ground wiremust have the crosssectional area of conductor in AC supply wire orlarger. However, if the conductor of AC supply wire is narrow than 2mm2,the conductor in ground wire must have 2mm2 crosssectional area orlarger.)

(1) When the I/O UnitB is mounted on a properly grounded metalportion of the power magnetics cabinet, it is grounded via a Metalsupport for direct installation or installation on the DIN rail (Referto 3.3.1 and 3.3.2.). Be sure to fix the I/O UnitB securely.

(2) When the I/O UnitB is mounted on a non metal or non groundedmetal portion of the power magnetics cabinet, it is necessary toconnect a ground wire to the Metal support for direct installation orinstallation on the DIN rail of a basic unit. It is necessary to connecta ground wire to the Metal support for direct installation orinstallation on the DIN rail of an extension unit. It is also necessaryto connect the ground wires to substantial earth ground.

(1) When a metal DIN rail is attached to a properly grounded metalportion, the I/O UnitB is grounded via a Metal support for directinstallation or installation on the DIN rail. Be sure to fix the I/OUnitB securely.

(2) When a nonmetal DIN rail is used, or a metal DIN rail is mounted ontoa nongrounded plate, it is necessary to connect a ground wire to theMetal support for direct installation or installation on the DIN railof a basic unit. It is necessary to connect a ground wire to the Metalsupport for direct installation or installation on the DIN rail of anextension unit. It is also necessary to connect the ground wires tosubstantial earth ground.

The interface unit is connected to the I/O Link. The interface unit isassumed to be group. The interface unit can be connected to any group.Up to 16 groups, namely up to 16 interface units, can be connected to asingle I/O Link.

The interface unit is provided with two I/O Link connectors, JD1A andJD1B. The JD1B connector of the interface unit must be connected to theJD1A connector of the I/O Link master or that of a slave in the previousgroup.

The JD1A connector of the interface unit should be connected to the JD1Bconnector of the subsequent group. If the interface unit is connected tothe last I/O Link group, keep the JD1A connector of the interface unitopen.

The I/O Link has 1024 input points and 1024 output points, as viewedfrom the master. So, the total of input or output points that can beoccupied by all slaves cannot exceed 1024. One I/O Link group has upto 256 input and output points. For the interface unit, however, thenumber of input points that can be occupied is limited to within 224,because 32 input points are already used for power on/off information.(The number of output points remains to be up to 256.)

The actual number of input/output points are:

Number of input points : Total number of input points of the inputunits and those of the input and output units.

Number of output points : Total number of output points of the outputunits and those of the input and output units.

The following tables list the number of I/O Links input and output pointsoccupied by an interface unit.

NOTEWhen calculating the number of actual output points,assume that the BOA12A1 occupies 16 points.

If the number of input points occupied by an interface unit is less than thenumber of output points occupied by the same interface unit, it is assumedthat the number of input points is equal to the number of output points.

The number of input points occupied by a single interface unit is at least32 more than the number of actual input points. Those 32 or more inputpoints are used for the power on/off information. The table below givesthe correspondence between the power on/off signals and unit numbers.When data is sent or received, the corresponding signal is set to 1. Whenthe power is turned off, the corresponding signal is set to 0. When thesystem retries an operation and detects the predetermined number oferrors or more errors than the predetermined number of errors, the errorstatus is established and the ERINF signal is set to 1.The detail of address assignment for power on/off information aredescribed in II PMC Programing 3.1 (2) on this manual.

The interface unit has four communications terminals, or channels, fordistributed links. (See Section 4.1, Connection Diagram.) Twocommunications cables (shielded twisted pair wire) can be connected toeach channel. To a single interface unit, up to eight communicationscables can be connected.

The total length of cables connected to a single channel must be 100m orless. (When two communications cables are connected to a singlechannel, the total length of the two cables combined must not exceed100m.)

A total of 30 DI/DO units can be connected to the four channels.

When 30 units are connected to the first communications cable : No unitscan be connected to the second to eighth cables.

When 10 units are connected to the first communications cable, 15 unitsto the second, and 5 units to the third : No units can be connected to thefourth to eighth cables.

When a single communications cable is connected to a single channel,install terminating resistors on both the interface unit and the basic uniton the other end of the communications cable. The terminating resistorcan be connected by setting the DIP switch.

When two communications cables are connected to a single channel,install terminating resistors on both basic units connected at the end of thecables. (Do not install the terminating resistor on the interface unit.) Theterminating resistor can be connected by setting the DIP switch.

Install a terminating resistor on an unused channel.

All DI/DO units must have unique unit numbers even if they areconnected to different channels.

M/S : If an error occurs, this LED is used to indicate the unit where the error is detected. The meaning of the LED indication is as follows:

ON : The error is detected in the interface unit.

OFF : The error is detected in the basic unit.

Nos. 1, 2, 4, 8, 16 : Indicate the number of the unit in which the error is detected.
