Safety Safety-1 FANUC Robotics is not and does not represent itself as an expert in safety systems, safety equipment, or the specific safety aspects of your company and/or its work force. It is the responsibility of the owner, employer, or user to take all necessary steps to guarantee the safety of all personnel in the workplace. The appropriate level of safety for your application and installation can best be determined by safety system professionals. FANUC Robotics therefore, recommends that each customer consult with such professionals in order to provide a workplace that allows for the safe application, use, and operation of FANUC Robotic systems. According to the industry standard ANSI/RIA R15.06, the owner or user is advised to consult the standards to ensure compliance with its requests for Robotics System design, usability, operation, maintenance, and service. Additionally, as the owner, employer, or user of a robotic system, it is your responsibility to arrange for the training of the operator of a robot system to recognize and respond to known hazards associated with your robotic system and to be aware of the recommended operating procedures for your particular application and robot installation. FANUC Robotics therefore, recommends that all personnel who intend to operate, program, repair, or otherwise use the robotics system be trained in an approved FANUC Robotics training course and become familiar with the proper operation of the system. Persons responsible for programming the system–including the design, implementation, and debugging of application programs– must be familiar with the recommended programming procedures for your application and robot installation. The following guidelines are provided to emphasize the importance of safety in the workplace. Safety-2 CONSIDERING SAFETY FOR YOUR ROBOT INSTALLATION Safety is essential whenever robots are used. Keep in mind the following factors with regard to safety: • • • • • • Keeping People and Equipment Safe The safety of people is always of primary importance in any situation. However, equipment must be kept safe, too. When prioritizing how to apply safety to your robotic system, consider the following: • • • • • Using Safety Enhancing Devices People External devices Robot(s) Tooling Workpiece Always give appropriate attention to the work area that surrounds the robot. The safety of the work area can be enhanced by the installation of some or all of the following devices: • • • • • • • • • Setting Up a Safe Workcell 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 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 the following guidelines to ensure that the workcell is set up safely. These suggestions are intended to supplement and not replace existing federal, state, and local laws, regulations, and guidelines that pertain to safety. • Sponsor your personnel for training in approved FANUC Robotics training course(s) related to your application. Never permit untrained personnel to operate the robots. 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 Staying Safe While Teaching or Manually Operating the Robot • Make sure all external devices are properly filtered, grounded, shielded, and suppressed to prevent hazardous motion due to the effects of electro–magnetic interference (EMI), radio frequency interference (RFI), and electro–static discharge (ESD). • Make provisions for power lockout/tagout at the controller. • Eliminate pinch points. Pinch points are areas where personnel could get trapped between a moving robot and other equipment. • Provide enough room inside the workcell to permit personnel to teach the robot and perform maintenance safely. • Program the robot to load and unload material safely. • If high voltage electrostatics are present, be sure to provide appropriate interlocks, warning, and beacons. • If materials are being applied at dangerously high pressure, provide electrical interlocks for lockout of material flow and pressure. 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. 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. - • Staying Safe During Automatic Operation 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. Safety-6 Staying Safe During Inspection Staying Safe During Maintenance • 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. • Lock out and tag out the power source at the controller according to the policies of your plant. • Turn off the compressed air source and relieve the air pressure. • If robot motion is not needed for inspecting the electrical circuits, press the EMERGENCY STOP button on the operator panel. • Never wear watches, rings, neckties, scarves, or loose clothing that could get caught in moving machinery. • If power is needed to check the robot motion or electrical circuits, be prepared to press the EMERGENCY STOP button, in an emergency. • 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 performing maintenance on your robot system, observe the following rules: Safety-7 • Never enter the work envelope while the robot or a program is in operation. • Before entering the work envelope, visually inspect the workcell to make sure no potentially hazardous conditions exist. • Never wear watches, rings, neckties, scarves, or loose clothing that could get caught in moving machinery. • Consider all or any overlapping work envelopes of adjoining robots when standing in a work envelope. • Test the teach pendant for proper operation before entering the work envelope. • If it is necessary for you to enter the robot work envelope while power is turned on, you must be sure that you are in control of the robot. Be sure to take the teach pendant with you, press the DEADMAN switch, and turn the teach pendant on. Be prepared to release the DEADMAN switch to turn off servo power to the robot immediately. • Whenever possible, perform maintenance with the power turned off. Before you open the controller front panel or enter the work envelope, turn off and lock out the 3–phase power source at the controller. • 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. 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. KEEPING MACHINE TOOLS AND EXTERNAL DEVICES SAFE 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. Programming Safety Precautions Implement the following programming safety measures to prevent damage to machine tools and other external devices. Safety-9 Mechanical Safety Precautions • Back–check limit switches in the workcell to make sure they do not fail. • Implement ‘‘failure routines” in programs that will provide appropriate robot actions if an external device or another robot in the workcell fails. • Use handshaking protocol to synchronize robot and external device operations. • Program the robot to check the condition of all external devices during an operating cycle. Implement the following mechanical safety measures to prevent damage to machine 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 to prevent undesired movement of the robot into the work area of machine tools and external devices. KEEPING THE ROBOT SAFE Observe the following operating and programming guidelines to prevent damage to the robot. Operating Safety Precautions The following measures are designed to prevent damage to the robot during operation. Programming Safety Precautions • Use a low override speed to increase your control over the robot when jogging the robot. • Visualize the movement the robot will make before you press the jog keys on the teach pendant. • Make sure the work envelope is clean and free of oil, water, or debris. • Use circuit breakers to guard against electrical overload. The following safety measures are designed to prevent damage to the robot during programming: • Establish interference zones to prevent collisions when two or more robots share a work area. Safety-10 • Make sure that the program ends with the robot near or at the home position. • Be aware of signals or other operations that could trigger operation of tooling resulting in personal injury or equipment damage. • In dispensing applications, be aware of all safety guidelines with respect to the dispensing materials. 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. ADDITIONAL SAFETY CONSIDERATIONS FOR PAINT ROBOT INSTALLATIONS 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. Paint System Safety Features 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. 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. • Staying Safe While Operating the Paint Robot 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. 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 work area of the entire paint station (workcell). • Know the work envelope of the robot and hood/deck and door opening devices. • Be aware of overlapping work envelopes of adjacent robots. • Know where all red, mushroom–shaped EMERGENCY STOP buttons are located. Safety-13 Staying Safe While Operating Paint Application Equipment • Know the location and status of all switches, sensors, and/or control signals that might cause the robot, conveyor, and opening devices to move. • 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 perform BEFORE starting automatic mode. • Make sure all personnel are outside the paint booth before you turn on power to the robot servo system. • Never enter the work envelope or paint booth before you turn off power to the robot servo system. • Never enter the work envelope during automatic operation unless a safe area has been designated. • Never wear watches, rings, neckties, scarves, or loose clothing that could get caught in moving machinery. • Remove all metallic objects, such as rings, watches, and belts, before entering a booth when the electrostatic devices are enabled. • Stay out of areas where you might get trapped between a moving robot, conveyor, or opening device and another object. • Be aware of signals and/or operations that could result in the triggering of guns or bells. • Be aware of all safety precautions when dispensing of paint is required. • Follow the procedures described in this manual. When you work with paint application equipment, observe the following rules, in addition to all rules for safe operation that apply to all robot systems. WARNING When working with electrostatic paint equipment, follow all national and local codes as well as all safety guidelines within your organization. Also reference the following standards: NFPA 33 Standards for Spray Application Using Flammable or Combustible Materials, and NFPA 70 National Electrical Code. Safety-14 Staying Safe During Maintenance • Grounding: All electrically conductive objects in the spray area must be grounded. This includes the spray booth, robots, conveyors, workstations, part carriers, hooks, paint pressure pots, as well as solvent containers. Grounding is defined as the object or objects shall be electrically connected to ground with a resistance of not more than 1 megohms. • High Voltage: High voltage should only be on during actual spray operations. Voltage should be off when the painting process is completed. Never leave high voltage on during a cap cleaning process. • Avoid any accumulation of combustible vapors or coating matter. • Follow all manufacturer recommended cleaning procedures. • Make sure all interlocks are operational. • No smoking. • Post all warning signs regarding the electrostatic equipment and operation of electrostatic equipment according to NFPA 33 Standard for Spray Application Using Flammable or Combustible Material. • Disable all air and paint pressure to bell. • Verify that the lines are not under pressure. When you perform maintenance on the painter system, observe the following rules, and all other maintenance safety rules that apply to all robot installations. Only qualified, trained service or maintenance personnel should perform repair work on a robot. • Paint robots operate in a potentially explosive environment. Use caution when working with electric tools. • When a maintenance technician is repairing or adjusting a robot, the work area is under the control of that technician. All personnel not participating in the maintenance must stay out of the area. • For some maintenance procedures, station a second person at the control panel within reach of the EMERGENCY STOP button. This person must understand the robot and associated potential hazards. Safety-15 • 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 the robot. • During robot operations, be aware of the robot’s movements. Excess vibration, unusual sounds, and so forth, can alert you to potential problems. • Whenever possible, turn off the main electrical disconnect before you clean the robot. • When using vinyl resin observe the following: • - Wear eye protection and protective gloves during application and removal - Adequate ventilation is required. Overexposure could cause drowsiness or skin and eye irritation. - If there is contact with the skin, wash with water. When using paint remover observe the following: - Eye protection, protective rubber gloves, boots, and apron are required during booth cleaning. - Adequate ventilation is required. Overexposure could cause drowsiness. - If there is contact with the skin or eyes, rinse with water for at least 15 minutes.

SAFETY PRECAUTIONS 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. 3 1. SAFETY PRECAUTIONS 1.1 OPERATOR SAFETY SAFETY PRECAUTIONS B–81535EN/02 Operator 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 operator safety. (1) Have the robot system operators attend the training courses held by FANUC. 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 still ready to move state and is waiting for a signal. In this state, the robot is regarded as still in motion. To ensure operator 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 operator can enter the work area without passing through the gate. Equip the gate with an interlock that stops the robot when the gate is opened. The controller is designed to receive this interlock signal. When the gate is opened 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 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 an operator enters the work area. (8) If necessary, install a safety lock so that no one except the operator 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. 4 B–81535EN/02 SAFETY PRECAUTIONS 1. SAFETY PRECAUTIONS (9) When adjusting each peripheral device independently, be sure to turn off the power of the robot. Safety gate which executes with opening the door. Fig.1.1 Safety Fence and Safety Gate 5 1. SAFETY PRECAUTIONS 1.1.1 Operator Safety SAFETY PRECAUTIONS B–81535EN/02 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 it is not necessary for the robot to operate, 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 the work area. (3) Install a safety fence with a safety gate to prevent any worker other than the operator from entering the work area unexpectedly and also 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 when the external EMERGENCY STOP button is pressed. See the diagram below for connection. External EMERGENCY STOP button Emergency stop board EMGIN11 EMGIN12 EMGIN21 EMGIN22 Note) Connect between EMGIN1 and EMGIN2 and between EMGIN21 and EMGIN22. EMGIN11, EMGIN12, EMGIN21 and EMGIN22 are on the emergency stop board. Fig.1.1.1 Connection Diagram for External Emergency Stop Switch 6 B–81535EN/02 1.1.2 Safety of the Teach Pendant Operator SAFETY PRECAUTIONS 1. SAFETY PRECAUTIONS While teaching the robot, it is necessary for the operator to enter the work area of the robot. It is particularly necessary to ensure the safety of the teach pendant operator. (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) When entering the robot work area and teaching the robot, be sure to check the location and condition of the safety devices (such as the EMERGENCY STOP button and the deadman switch on the teach pendant). FANUC’s teach pendant has a switch for enabling or disabling the robot operation from the teach pendant and a deadman switch in addition to the EMERGENCY STOP button. The switches function as follows. EMERGENCY STOP button : Pressing this button always brings the robot to an emergency stop, irrespective of the state of the enable/disable switch and the mode switch of operator panel. Deadman switch : The function of this switch depends on the state of the enable/disable switch and the mode 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 is in the enable position – Releasing the deadman switch brings the robot to an emergency stop. When the mode switch is in the TI position and the enable/disable switch is in the disable position – The robot is brought to an emergency stop regardless of the operation of the deadman switch. Note)The deadman switch is provided to bring the robot to an emergency stop when the operator releases the teach pendant in an emergency. (4) The teach pendant operator should pay careful attention so that no other 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. 7 1. SAFETY PRECAUTIONS SAFETY PRECAUTIONS B–81535EN/02 (5) When entering the robot work area, the teach pendant operator should enable the teach pendant whenever he or she enters the robot work area. In particular, while the teach pendant enable switch is off, make certain that no start command is sent to the robot from any operator panel other than the teach pendant. 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 of the teach pendant enable switch and the mode switch the remote switch on the operator panel. Operator panel mode switch Teach pendant enable switch Remote condition Teach pendant Operator panel Peripheral devices T1 On Independent Allowed to start Not allowed Not allowed AUTO Off Local Not allowed Allowed to start Not allowed AUTO Off Remote Not allowed Not allowed Allowed to start (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. 8 B–81535EN/02 1.1.3 Safety During Maintenance SAFETY PRECAUTIONS 1.

(2) When disconnecting the pneumatic system, be sure to reduce the supply pressure. (3) Before the start of teaching, check that the robot and its peripheral devices are all in the normal operating condition. (4) If it is necessary to enter the robot work area for maintenance when the power is turned on, the worker should indicate that the machine is being serviced and make certain that no one starts the robot unexpectedly. (5) Do not operate the robot in the automatic mode while anybody is in the robot work area. (6) When it is necessary to maintain the robot alongside a wall or instrument, or when multiple workers are working nearby, make certain that their escape path is not obstructed. (7) 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. (8) 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. (9) When replacing or reinstalling components, take care to prevent foreign matter from entering the system. (10) When handling each unit or printed circuit board in the controller during inspection, turn off the power of the controller and also turn off 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 the controller. 9 1. SAFETY PRECAUTIONS SAFETY PRECAUTIONS B–81535EN/02 1.2 SAFETY OF THE TOOLS AND PERIPHERAL DEVICES 1.2.1 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. 1.2.2 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) Employ a limit switch or mechanical stopper to limit the robot motion so that the robot does not come into contact with its peripheral devices or tools. 10 B–81535EN/02 SAFETY PRECAUTIONS 1.

(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) Measure the voltage of the 200–VAC input to the power supply module. If the voltage is 170 VAC or lower, adjust the input voltage. (Action 2) Check that CRR78 of the emergency stop board and CX3 and CX4 of the power supply module are securely connected. Check the cables of the emergency stop board and power supply module for a break. (Action 3) Check the EMERGENCY STOP line (teach pendant emergency stop, teach pendant enable/disable switch, teach pendant deadman switch, operator panel emergency stop, external emergency stop input, fence input) for a possibility of an instantaneous interruption. If the software cannot judge the cause of the alarm at an instantaneous interruption of the EMERGENCY STOP line, this alarm occurs. (Action 4) Replace the emergency stop unit. (Action 5) If an alarm occurs on all axes, the power supply module may be faulty. Replace the power supply module.

(Action 1) Check whether the motor brake has been released. (Action 2) Make sure that the servo amplifier CZ2L to N are connected tightly. (Action 3) Check to see if the load is greater than the rating. If greater, reduce it to within the rating. (If the load is too greater, 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 4) Check each phase voltage of the CZ1 connector of the three–phase power (200 VAC) input to the servo amplifier. If it is 170 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 an alarm.) (Action 5) If the line voltage is 170 VAC or higher, replace the power supply module or servo amplifier module. (Action 6) Check disconnection of robot connection cable (RMP).

TROUBLESHOOTING MAINTENANCE B–81535EN/02 Reference Relationships among the OVC, OVL, and HC alarms Overview This section points out the differences among the OVC, OVL, and HC alarms 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 OHAL2 Thermal relay in the servo amplifier OHAL1 Thermal relay in the separate regenerative discharge unit DCAL HC High current alarm Servo amplifier 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. 2) OVC and OVL alarms (overcurrent and overload alarms) The OVC and OVL 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 OVL 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 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 thermal relay, thus causing the motor to burn before the thermal relay detects an abnormally high temperature. Temperature Start Stop Start Stop Start Thermal time constant of the motor is high. Temperature at which the winding starts to burn Thermal time constant of the thermal relay is low. Time Fig.1 Relationship between the temperatures of the motor and thermal relay on start/stop cycles 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. 53 3. TROUBLESHOOTING MAINTENANCE B–81535EN/02 To sum up, a double protection method is used; the OVC alarm is used for protection from a short–time overcurrent, and the OVL alarm is used for protection from long–term overload.

TROUBLESHOOTING (95) SRVO–296 SVAL1 DCAL alarm (Group : i Axis : j) (Explanation) The regenerative discharge energy is too high to be dissipated as heat. (To move the robot, the servo amplifier supplies energy to the robot. When going down, the robot moves along the vertical axis as the potential energy reduces. If a reduction in the potential energy is larger than the amount of acceleration energy, the servo amplifier receives energy from the motor. This also occurs at deceleration even when no gravity is applied. The energy that the servo amplifier receives from the motor is called regenerative energy. The servo amplifier dissipates this energy as heat. If the amount of the regenerative energy dissipated as heat is smaller than was received, the remainder is stored in the servo amplifier, causing this alarm.) The LED indication on the power supply module is “8” (DCAL: regenerative energy adder detection). (Action 1) This alarm may occur if the robot is subjected to frequent acceleration/deceleration or if the vertical axis generates a large amount of regenerative energy.

REPLACING A UNIT MAINTENANCE B–81535EN/02 7.15 REPLACING BATTERY 7.15.1 Battery for Memory Backup (3 VDC) The programs, and system variables are stored in the SRAM in the Robot control board. The power to the SRAM memory is backed up by a lithium battery mounted on the front panel of the Robot control board. The above data is not lost even when the main battery goes dead. A new battery can maintain the contents of memory for about 4 years (Note). When the voltage of the battery becomes low, the battery alarm LED on the operator panel is lit, and 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. Turning on the power to the in this state causes system not to start and LED of seven segment on the Robot control board to be displayed “1” because the contents of memory are lost. Clear the entire SRAM memory and reenter data after replacing the battery. Important data should be saved to the memory card or floppy disk beforehand in case of emergency. When replacing the memory backup battery, do so while the robot controller 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 4 years after the introduction of the robot. Replacing the lithium battery (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 detach its connector. 154 B–81535EN/02 MAINTENANCE Battery latch 7. REPLACING A UNIT Battery connector Lithium battery (5) Remove the old battery, insert a new one into the battery holder, and attach the connector. Confirm that the battery is latched firmly. WARNING Using other than the recommended battery may result in the battery exploding. Replace the battery only with the specified battery (A02B–0200–K102). CAUTION Complete 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 backed up before battery replacement. 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. 155 III CONNECTION CONNECTIONS B–81535EN/02 1 1.

PERIPHERAL INTERFACE B APPENDIX B–81535EN/02 PERIPHERAL INTERFACE Peripheral I/O (UI/UO) are a group of specialized signals whose usage is decided by the system. These signals are connected with a remote controller and the peripheral devices via the following interfaces and I/O links and they are used to control the robot from the outside. D The JD1A interface (The process I/O board, the I/O Unit MODEL A and the MODEL B are connected as the slave of I/O link to R–J3iB Mate.) (on master mode) D The JD1B interface (CNC and PLC are connected as a master of I/O link to R–J3iB Mate.) (on slave mode) D CRM9 interface Refer to the operator’s MANUAL for detail informations. 238 APPENDIX B–81535EN/02 B.1 SIGNAL TYPES B. PERIPHERAL INTERFACE The tables below list the special signals of the R–J3iB Mate robot controller. Input signals (See Subsection B.2.1.) Signal *HOLD RESET START ENBL PNS1 PNS2 PNS3 PNS4 Description Temporary stop Alarm release Cycle start Enable Program select (*1) Program select (*1) Program select (*1) Program select (*1) NOTE PNS (program select input) (optional) Output signals (See Subsection B.2.1.) Signal Description CMDENBL FAULT BATALM BUSY Input acceptable Alarm Battery alarm Busy 239 B. PERIPHERAL INTERFACE APPENDIX B–81535EN/02 B.2 I/O SIGNALS B.2.1 Fellowing is each input signal. Input Signals Hold input signals, *HOLD, UI [ 1 ] The remote controller uses the hold signal to halt the robot. Because *HOLD input signal is a inverted signal, normally set the signal on. When the signal goes off, the following is executed: D The robot is decelerated until its stops, then the program execution is halted. D If ENABLED is specified at “Break on hold” on the general item setting screen, the robot is stopped, an alarm is generated, and the servo power is turned off. (Standard setting: DISABLED) Fault reset input signal, RESET, UI [ 2 ] The RESET signal cancels an alarm. If the servo power is off, the RESET signal turns on the servo power. The alarm output is not canceled until the servo power is turned on. The alarm is canceled at the instant this signal falls in default setting. D If TRUE is specified at “CSTOPI for ABORT” on the system configuration screen, the RESET signal resets an alarm and aborts the currently selected program. (Standard setting: FALSE) D To have alarms reset the instant the RESET signal rises, it is necessary to specify RISE at “Detect FAULT RESET signal” on the system configuration screen. (Standard setting: FALL) Start input signal, START, UI [ 3 ] (validated in the remote state) The START signal has two functions. It can select or collate a program and start the program. D When the START signal goes high, PNS1 to PNS4 are read and the corresponding program is selected or collated. Whether is program is selected or collated is specified by the setting of system variable $SHELL_CFG.$NUM_RSR [1]. (See the description of signals PNS1 to PNS4.) D When the START signal goes low, the current program is started from the line at which the cursor is placed (current line). D If TRUE is specified at “START for CONTINUE only” on the system configuration screen, only a program on hold can be started. (Standard setting: FALSE) Enable input signal, ENBL, UI [ 4 ] The ENBL signal allows the robot to be moved and places the robot in the ready state. When the ENBL signal is off, the system inhibits a jog feed of the robot and activation of a program including a motion (group). A program which is being executed is halted when the ENBL signal is set off. NOTE When the ENBL signal is not monitored, strap the signal with the ground. 240 B–81535EN/02 APPENDIX B. PERIPHERAL INTERFACE Program number selection signals, PNS1 to PNS4, UI [ 5 to 8 ] (validated in the remote state) A program number selection signal has two functions. When the START signal goes on, PNS1 to PNS4 are read and the corresponding program is selected or collated. Whether the program is selected or collated is specified by the setting of system variable $SHELL_CFG.$NUM_RSR [1]. B.2.2 Fellowing are peripheral device interface output signals. D In the program end state, a program is selected or collated according to the state (0 or 1) of the PNS signals. The current line of the selected or 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 the current program. If the programs do not agree with each other, an error occurs. D If all PNS signals are low in the program end state, the current program is executed from the current line. If no programs are selected, an error occurs. D A halted program can be resumed only when all PNS signals are set off. Otherwise, an error occurs. D While a program is being executed, the PNS signals are ignored. Output Signals Command enable output signal, CMDENBL, UO [ 1 ] The CMDENBL signal is output when the following conditions are satisfied. The CMDENBL signal indicates that the remote controller can start a program including a motion (group). D The remote conditions are satisfied. D The ready conditions are satisfied. D The continuous operation mode is selected (the single step mode is disabled). Fault output signal, FAULT, UO [ 2 ] The FAULT signal is output when an alarm occurs in the system. The RESET signal cancels the alarm. If a warning (WARN alarm) occurs, the FAULT signal is not output. Battery alarm output signal, BATALM, UO [ 3 ] The BATALM signal indicates that the voltage of the battery for supporting the memory has dropped. Replace the battery while keeping the power of the controller on. To have the BATALM signal generated also when the BZAL/BLAL alarm occurs, it is necessary to set the $BLAL_OUT.$BATALM_OR system variable. It is also possible to have the specified SDO output when the BZAL/BLAL alarm occurs. Busy output signal, BUSY, UO [ 4 ] The BUSY signal is output while a program is being executed. The BUSY signal is not output while a program is being halted. 241 B. PERIPHERAL INTERFACE APPENDIX B–81535EN/02 B.3 SPECIFICATIONS OF DIGITAL INPUT/OUTPUT B.3.1 Overview B.3.2 Input/Output Hardware Usable in the R-J3iB Mate Controller This section describes the external specifications of digital and analog input/output in the R–J3iB Mate controller. The R–J3iB Mate controller can use up to 512 digital input and output points or an equivalent number of analog input and output points. One analog input/output point uses the resources equivalent to those used by 16 digital I/O points. The R–J3iB Mate can use a total of up to 512 I/O points. The R–J3iB Mate controller can use the following I/O hardware. - Process I/O printed circuit board - I/O unit model A The process I/O printed circuit board and the I/O unit model A can be used together. 242 B–81535EN/02 APPENDIX B. PERIPHERAL INTERFACE B.3.3 Software Specifications (1) RDI/RDO These 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 of points that can be used for the connector at the wrist depends on the individual robot. (2) SDI/SDO The signal No. that is determined at hardware can be changed by software operation. (3) Analog I/O An analog I/O signal can access the analog I/O port (optional) on the process I/O printed circuit board or the I/O port on the analog I/O module (used together with the I/O unit model A). It reads and writes the digital value converted from the analog value of the I/O voltage. It means that the value does not always represent the real I/O voltage. (4) Group I/O Group I/O is a function which can input or output multiple DI/DO signals as binary codes. Any number of continuous signals of up to 16 bits can be set for its use. It can be set in the menu DETAILS on the group I/O screen. 243 C. OPTICAL FIBER CABLE C APPENDIX B–81535EN/02 OPTICAL FIBER CABLE The R–J3iB Mate uses fiber optic cables for communication between the robot control board and servo amplifier module and between the servo amplifier module and servo amplifier module. Observe the following cautions when handling these fiber optic cables. (1) Protection during storage When the electrical/optical conversion module (mounted on the printed) circuit board and the fiber optic cable are not in use, their mating surfaces must be protected with the lid and caps with which they are supplied. If left uncovered, the mating surfaces are likely to become dirty, possibly resulting in a poor cable connection. Electrical/optical conversion module Fiber optic cable Lid Fiber optic cable caps Fig.C (a) Protection of electrical/optical conversion module and fiber optic cable (when not in use) 244 C. OPTICAL FIBER CABLE APPENDIX B–81535EN/02 (2) Fiber optic cable D Grasp the optical connector firmly when connecting or disconnecting the cable. Do not pull on the fiber optic cord itself. (The maximum tensile strength between the fiber cord and connector is 2 kg. Applying greater force to the cord is likely to cause the connector to come off, making the cable unusable.) Fiber optic cord diameter : 2.2 mm 2 cords Tensile strength : Fiber optic cord :7 kg per cord Between fiber optic cord and connector : 2 kg Minimum bending radius of fiber optic cord :25 mm Flame resistance : Equivalent to UL VW–1 Operating temperature : –20 to 70°C 8.2 6.7 19 max. 60 max. 35typ. 21 Bush Code Reinforced cover Fig.C (b) External dimensions of external optical cable Unit : mm D Afler it is connected, the optical connector is automatically locked by the lock levers on its top. To remove the connector, release the lock levers and pull the connector. D Although optical connectors cannot be connected in other than the correct orientation, always take note of the connector’s orientation before making the connection. D Take care to keep both parts of the optical connector (cable side and PCB side) clean. If they become dirty, wipe them with tissue paper or absorbent cotton to remove dirt. The tissue paper or absorbent cotton may be moistened with ethyl alcohol. Do not use any organic solvent other than ethyl alcohol. D Do not clamp the uncovered portion of the cable with a nylon band. 245 Index B–81535EN/02 [A] [E] Emergency Stop Board (A20B–1008–0010, –0011), 116 Adjustment and Checks at Installation, 225 Alarm
