Safety-2 CONSIDERING SAFETY FOR YOUR ROBOT INSTALLATION MARMI120I07021E REV A 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 MARMI120I07021E REV A · 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 MARMI120I07021E REV A · 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 MARMI120I07021E REV A 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.

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 MARMI120I07021E REV A 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 MARMI120I07021E REV A · 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 MARMI120I07021E REV A 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.

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 MARMI120I07021E REV A · 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.

PERIODIC MAINTENANCE Follow the procedure stated below to replace the grease in the J1–, J2–, and J3–axis reducers and the J4– and J5–axis gearboxes once every three years or after 11,520 hours of operation. See Fig. 3.1 for greasing points. 1) Remove the seal bolts from the J1–, J2–axis grease outlets shown in Fig. 3.1. Also remove the plug of J3–axis grease outlet, the flat–bolts and sealing washers from the J4– and J5–axis grease outlets. 2) Uncap the grease nipples at the J1–, J2–, J3–, and J4–axis grease inlets. When the J5–axis grease is supplied remove the flat–head bolt from the J5–axis grease inlet and attach the grease nipple to the J3–axis or J4–axis grease inlet. 3) Supply the grease specified in Table 3.2 to the J1–, J2–, and J3–axis reducers, and J4– and J5–axis gearboxes through their respective grease nipples. Keep greasing until the new grease pushes out the old grease and comes out from each grease outlet. Ensure that the amount of the newly supplied grease equals the amount of the drained grease so that the grease bath will not become full. 4) Wind sealing tape around the J1–, J2–axis seal bolts and J3–axis plug you removed, and attach them to the respective grease outlets. 5) Attach the J4– and J5–axis flat–head bolts and the J4– and J5–axis sealing washers to the respective grease inlets and outlets. 6) When finally returning the grease nipple used at another location to the original position, be sure to wind sealing tape around the threads part. In addition, be sure to cap the grease nipple for each axis.

ADJUSTMENTS ADJUSTMENTS Each part of the robot mechanical units is set to the best condition before the robot is shipped to the customer. The customer does not need to make adjustments on the robot when it is delivered. If a mechanical unit of the robot has a large backlash because of a long–term use or component replacement, make adjustments using to this section. 28 5. ADJUSTMENTS 5.1 REFERENCE POSITION AND MOVING RANGE MAINTENANCE B–81765EN/01 1) Reference position and operation limit Each controlled axis is provided with a reference position and operation limit. A state in which a controlled axis has reached its operation limit is known as overtravel (OT). For each axis, an overtravel condition can be detected at the both ends of it. As long as the robot does not encounter a servo section error or system error that causes a reference position to be lost, the robot is controlled in such a way that it will not go out of its operation area. Fig. 5.1 (a) to Fig. 5.1 (g) show the reference position and operation area (stroke) of each axis and their mechanical stopper positions.

ADJUSTMENTS 5.2 Mastering is an operation performed to associate the angle of each robot axis with the pulse count value supplied from the absolute pulse coder connected to the corresponding axis motor. To be specific, mastering is an operation for obtaining the pulse count value corresponding to the zero position. 5.2.1 The current position of the robot is determined according to the pulse count value supplied from the pulse coder on each axis. MASTERING General Mastering is factory–performed. It is unnecessary to perform mastering in daily operations. However, mastering becomes necessary after: D Motor replacement. D Pulse coder replacement. D Reducer replacement. D Cable replacement. D Batteries for pulse count backup in the mechanical unit have gone dead. NOTE Robot data (including mastering data) and pulse coder data are backed up by their respective backup batteries. Data will be lost if the batteries go dead. Replace the batteries in the control and mechanical units periodically. An alarm will be issued to warn the user of a low battery voltage. Mastering method Table 5.2.1 Types of Mastering Jig position mastering This is performed using a mastering jig before the machine is shipped from the factory. Zero-position master- This is performed with all axes set at the 0–degree posiing (eye mark mastion. A zero–position mark (eye mark) is attached to tering) each robot axis. This mastering is performed with all axes aligned to their respective eye marks. Quick mastering This is performed at a user–specified position. The corresponding count value is obtained from the rotation speed of the pulse coder connected to the relevant motor and the rotation angle within one rotation. Quick mastering uses the fact that the absolute value of a rotation angle within one rotation will not be lost. One-axis mastering This is performed for one axis at a time. The mastering position for each axis can be specified by the user. This is useful in performing mastering on a specific axis. Mastering data entry Mastering data is entered directly. Once mastering is performed, it is necessary to carry out positioning, or calibration. Positioning is an operation in which the control unit reads the current pulse count value to sense the current position of the robot. When the battery backup of the pulse coder is interrupted by cable replacement, you can perform quick mastering to perform calibration to the original position. When the phase of the pulse coder is changed mechanically as a result of replacement of the motor, reducer, and so forth, you cannot perform quick mastering. In this case, you must perform jig position mastering to calibrate the position accurately. 34 5. ADJUSTMENTS MAINTENANCE B–81765EN/01 NOTE If mastering is performed incorrectly, the robot may behave unexpectedly. This is very dangerous. So, the positioning screen is designed to appear only when the $MASTER_ENB system variable is 1 or 2. After performing positioning, press F5 [DONE] on the positioning screen. The $MASTER_ENB system variable is reset to 0 automatically, thus hiding the positioning screen. 5.2.2 Resetting Alarms and Preparing for Mastering Alarm displayed Before performing mastering because a motor is replaced, it is necessary to release the relevant alarm and display the positioning menu. “Servo 062 BZAL” or “Servo 075 Pulse mismatch” Procedure Preparing the Robot for Mastering Step 1 To reset the “Servo 062 BZAL” alarm, follow steps 1 to 7. 1 2 3 4 5 6 7 Press MENUS.

To confirm that mastering was performed normally, check that the current–position display matches the actual position of the robot, using this procedure. a) Replay the taught operation of the robot to set each axis to zero degrees, and visually check that the zero–degree position marks shown in Fig. 5.2 are aligned. b) Replay a specific portion of the program, and check that the robot has moved to the taught position. 2) Possible alarms in positioning The following paragraphs describe alarms that may occur in positioning and explain how to handle them. a) BZAL alarm This alarm is raised if the voltage of the pulse coder backup battery becomes 0V when the controller power is off. Mastering must be performed again because the counter has already lost data. b) BLAL alarm This alarm indicates that the voltage of the pulse coder backup battery is too low to run the pulse coder. If this alarm is issued, replace the backup battery soon while keeping the power on, and check whether the current–position data is correct, using a method described in item (1). c) CKAL, RCAL, PHAL, CSAL, DTERR, CRCERR, STBERR, and SPHAL alarms If any of these alarms is issued, contact your FANUC service representative. A motor may have to be replaced. 51 B–81765EN/01 5.3 J5–AXIS GEAR BACKLASH ADJUSTMENTS 5. ADJUSTMENTS MAINTENANCE If the backlash in the J5–axis is greater than the allowable value (output axis angle of 4.5 minutes) listed in Table 4.2 (b), (d), make backlash adjustments, using this procedure. (See Fig. 5.3.) The J5–axis structure is common to the ARC Mate 120iB, M–16iB/20, ARC Mate 120iB/10L, and M–16iB/10L. 1 Place the robot in a posture of J3 = 0°, J4 = +90° and J5 = J6 = 0°. 2 Remove the twelve M5 10 flat–head bolts, and dismount the J5–axis gearbox cover (A290–7216–X524) from the J3 arm (A290–7216– X402 and X404), and suck internal grease. 3 Adjust the gear 3 assembly and gear J5–4, then adjust the gear 2 assembly and gear 3 assembly. J3 arm A290–7216–X402, X404 Input Gear A290–7216–X511 Gear 3 assembly A290–7216–V502 Gear J5–4 J6 Housing Gear 2 assembly A290–7216–V501 Bolt with washer : M6 14 (4pcs) Plane washer (4pcs) Very low head bolt M5 10 (12pcs) Seal bolt with washer : M6 12 (10pcs) Cover A290–7216–X524 Gear 3 assembly A290–7216–V502 Just loosen this two bolts. Adjust the backlash by turning the gear 3 assembly around this bolt. Fig 5.3 J5–axis gear backlash adjustments 1) Gear 3 assembly and gear J5–4 backlash adjustments 1 Remove the four M6 14 seal bolts with a washer, and retract the gear 2 assembly (A290–7216–V501) to such a point that it will not be engaged with the gear 3 assembly (A290–7216–V502). 2 Of the 10 M6 12 seal bolts with a washer securing the gear 3 assembly, loosen but leave the two bolts shown in the figure, and remove the other eight bolts. 52 5. ADJUSTMENTS MAINTENANCE B–81765EN/01 3 Rotating the gear 3 assembly in the right and left directions about the reference bolt changes the amount of the backlash with J5–4. Shift the position of the gear 3 assembly so that the backlash can be reduced, and temporarily secure the assembly with the remaining two bolts. 4 Rotate the J6 housing (gear J5–4) within the stroke (±140°), and check whether the rotation is abnormally heavy and any portion has a serious backlash. Repeat the above operation until the backlash is reduced to within the maximum allowable value and the engagement and rotation torque becomes appropriate. 5 When you have completed adjustments, use new 10 M6 12 seal bolts with a washer to secure the gear 3 assembly with the specified torque. Remove also the two bolts used during adjustments, and replace them with new seal bolts. NOTE Once you loosen seal bolts, sealing properties deteriorate, which can lead to grease leakage. When assembling the gear, use new seal bolts. 2) Gear 2 assembly and gear 3 assembly backlash adjustments 1 Shift the gear 2 assembly in a direction vertical to the gear 3 assembly and input gear (A290–7216–X511) so that the backlash is reduced, and fix the gear 2 assembly to the J3 arm with two M6 12 seal bolts with a washer. 2 Rotate the gear 2 assembly, and check the operation of the J5–axis by operating it within its stroke (–140° to +140°). Repeat step 1 for reducing the backlash until the gears will not interfere with each other. When you have completed adjustments, use new four M6 14 bolts with a washer (with Loctite 262 applied) and plain washers, and tighten them to the specified torque to secure the assembly. 3 Make sure that the total backlash in the J5–axis unit is lower than the maximum allowable value (output axis angle of 4.5 minutes) listed in Table 4.2 (b), (d). If the requirement is not satisfied, go back to 1 of procedure (1). 4 Fix the J5–axis gearbox cover to the J3 arm with twelve M5 10 flat–head bolts. 5 Apply the specified grease to the J5–axis gearbox by following the grease replacement procedure stated in Section 3.2. 6 Perform mastering as stated in Section 5.2. 53 B–81765EN/01 5.4 BRAKE RELEASE MAINTENANCE 5.

CABLE REPLACEMENT 8 MAINTENANCE B–81765EN/01 CABLE REPLACEMENT Replace the cables of the robot once every four years. If a cable is broken or damaged, replace it according to the procedure described in this chapter. Cautions in handling the pulse coder cable When transporting, installing, or maintaining the robot, do not detach the pulse coder cables carelessly. The cables are provided with the marking tie and label shown below. If you detached any cable with the marking tie, you need to perform mastering for the robot. Do not detach any connector unless you replace a motor, pulse coder, reducer, or cable. Fig 8 (a) Marking tie Fig 8 (b) Label If there is a break in or any other damage to a cable, replace the cable according to the procedure described in this chapter. If the connector of a pulse coder cable (K101, K102, K131, K132, K201, or K202) is detached, the data about the absolute position of the robot is lost. Once any of these cables is replaced, perform quick mastering while referencing Section 5.3. If the data is lost because of a break in a cable, also perform quick mastering to calibrate the robot into the previous absolute position. 85 B–81765EN/01 8.1 CABLE DRESSING MAINTENANCE 8. CABLE REPLACEMENT After a cable is replaced individually rather than in kit, clamp it with rubber bushings and nylon ties (cable ties) at the specified positions listed in Table 8.1.

In this case, clamping the cables with nylon ties as shown in the figure, using inline connector holes in the J6, will make it easy to pull the cables. If the arm is a long type (M–16iB/10L or ARC Mate 120iB/10L), remove the plate (A290–7216–X536) from the support (A290– 7216–X535). 12 While referring to Fig. 8.2 (c), remove the two M6 10 bolts that retain the plate (A290–7216–X441), and pull out the cables from the hollow section of the J3 reducer in the following sequence: (i) Air hose (ii) J3P and J4P (iii) Cable part that extends beyond the Teflon tube (iv) EE1 (v) EE8 or W/F2 (vi) J3M and J4M Note that, if this sequence is not observed precisely, it is impossible to pull out the cables. When installing the cables, reverse the procedure. 13 Remove the cable kit completely from the robot main body. 14 Mount a new cable kit by reversing the above procedure. First, while referring to Fig. 8.2 (f), mount the J6 clamp (A290–7216–X534) and the J5–2 clamp (A290–7216–X531) to the K202 wrist cable by observing the clamp–to–clamp distance (205 mm) precisely (as measured with a rule). Also exercise sufficient care to avoid having twisted pairs entangled. 15 When assembling the J5–axis section, make sure that unbundled twisted pairs will not be entangled in the hollow section or caught in the J6 housing. When mounting the J5–2 clamp (A290–7216– X531) to the J5–2 cover, use two new M4 6 sealing bolts. After passing the wrist cable in the J5–axis hollow section, attach a nylon tie to the hole in the J5–2 clamp (A290–7216–X531) to fasten the cable. 16 When attaching the J5–2 cover to the J3 arm, make sure that the unbundled twisted pairs are not caught in between. (If it is likely that the unbundled wires may be rubbed against the edge of a sheet metal, bind them with nylon ties or the like to keep them away from the sheet metal.) 17 When attaching the plate (A290–7216–X441) to the plate (A290–7216–X442) for the J3 casing, place the plates in such a way that, when the plate (A290–7216–X441) is concave as viewed from the top, the cable from the J2 arm side will look natural (with no twist). Twist the plate (A290–7216–X441) to 90_ from the current position in such a way that the plate looks concave as viewed from the front, and then mount it to the plate (A290–7216–X442). 18 Mount the cable kit by following steps 7 to 2 in the stated order. 90 8. CABLE REPLACEMENT MAINTENANCE B–81765EN/01 19 Put the rubber boots back to the previous position. Before mounting the J1 connector board on the J1 base, push the OT strapping connectors into the rubber boots, and bind the openings of both the RM1 and RP1 rubber boots with nylon ties. Mount the J1 connector board to the J1 base while exercising care to avoid having the unbundled wires caught in between. 20 Put the J2–/J3–axis Cornex cover back onto the cable kit, and fasten it with a nylon tie; keep the nylon tie rather loose.
