A FabWorld system can be tailored to meet ever-changing production needs because the modular design allows for the addition of positioners and operator stations at a later date for increased versatility. FabWorld systems are designed especially for low and medium volume production. A FabWorld system consists of a K6 or a K10 robot, an MRC robot controller, and one, two, or three positioners. You can use different types of positioners, either singly or in combination, to meet your specific needs. Available positioner options include a multi-plane (tilt/rotate) positioner, a rotary plane (headstock/ tailstock) positioner, and a stationary flat table. A stationary tack-welding table is also an option. Standard FabWorld systems have either one or two stations (zones). By adding optional equipment, a FabWorld cell can be configured with up to three stations. Each station includes a positioner, an operator station, safety fencing, photo eyes, arc screens, and safety mats. Many different FabWorld system configurations are possible due to the different modules that are available. 1.1 ABOUT THIS DOCUMENT This manual provides operation instructions for the FabWorld system. In addition to this introduction, the manual includes the following sections: • Section 2: Safety • Section 3: Description of Equipment • Section 4: Operation • Section 5: Maintenance • Appendices The Safety Section provides information regarding the safe use and operation of the FabWorld system. The Description of Equipment Section provides a detailed description of the major components of the FabWorld system. This section also includes a table of component specifications.

Both types of op-station have the following controls: • Emergency Stop • Robot Hold • Station Ready • Alarm • Master Job Start • Cycle Start • Reset FabWorld Operator's Manual Page 22 MOTOMAN CYCLE START CYCLE START MOTOMAN ALARM ROBOT HOLD STATION READY RESET MASTER JOB START POSITIONER AUTO/MAN OPERATOR STATION ENABLE/DISABLE ESTOP SERVO ON WARNING: WARNING: WARNING! NOT ENTER DODO NOT ENTER ROBOT WORK ROBOT WORKAREA AREA Figure 3-4 Operator Station (Op-Station) In addition to the controls listed above, the master op-station also has the following controls: • Servo On • Positioner Auto / Manual • Op-Station Enable / Disable The following sections describe each of the op-station controls. 3.8.1 Emergency Stop (E-Stop) The operator station E-Stop, the robot E-Stop, the photo eyes, zone ring monitor, and the FabWorld safety mats are connected in series in the E-Stop circuit. If the E-Stop circuit is interrupted, the robot and positioner go into the E-Stop condition. The operator station E-Stop light comes on when the E-Stop button is pressed. FabWorld Operator's Manual Page 23 MOTOMAN 3.8.2 Hold The op-station HOLD button is a normally closed pushbutton and is connected to the MRC to cause the robot to go into the Hold condition when the button is pressed. 3.8.3 Cycle Start The CYCLE START palm buttons located on both ends of the op-station use an anti-tiedown technique for robot input. The anti-tiedown timer is set for 10 seconds. Holding the palm buttons down for more than 10 seconds causes the timer to time out and prevents the input from reaching the robot. The CYCLE START buttons are connected to robot Input #1. 3.8.4 Station Ready The STATION READY lamp is interlocked with the robot CUBE #1 output. The robot Outputs #1, 2, and 3 turn on the STATION READY lamp. 3.8.5 Alarm The ALARM lamp is connected to the robot Alarm Occurrence output. The ALARM lamp turns on when the robot encounters a major or minor alarm condition. 3.8.6 Servo On The SERVO ON pushbutton is connected to the robot Servo On input. The robot servo motors will turn on when the SERVO ON pushbutton is pressed and an EStop condition does not exist. 3.8.7 Positioner Auto / Manual The POSITIONER AUTO / MANUAL selector switch is used to select Automatic or Manual Mode for the positioners. The selector switch is connected to robot Input #2. When the selector switch is in the Automatic position, the robot will process the part after the positioner sweeps. In Manual Mode, the robot will not process the part after the positioner sweeps. This function is dependent on the structure of the master job. 3.8.8 Master Job Start FabWorld Operator's Manual Page 24 MOTOMAN The MASTER JOB START pushbutton is connected to the robot external start input. The robot will start the currently active job when this pushbutton is pressed if the robot is in Play Mode and the servo motors are on. 3.8.9 Operator Station Enable / Disable The OPERATOR STATION ENABLE / DISABLE selector switch is used to transfer primary control of the FabWorld cell from the MRC to the Op-Station. The REMOTE MODE button on the MRC playback box lights when the opstation is enabled. Most programming pendant functions are disabled. 3.8.10 Reset The RESET pushbutton is connected to the robot alarm reset input. Any alarm or error condition will be cleared when this button is pressed. In addition, the RESET pushbutton and the right CYCLE START palm button are interlocked. When pressed simultaneously, thes two pushbuttons enable the positioners if the robot servo motors are on. The positioner needs to be enabled at initial power up or at emergency stop or shock sensor condition. NOTE: When resetting the multi-plane positioner, some table motion may occur. Do not reset the positioner with the robot close to tooling. If an E-Stop occurs during programming, be sure to reset the table before resuming programming. This will ensure that the table is in the same position as before the E-Stop. 3.9 WELDING POWER SOURCE The Excel-Arc power source (Figure 3-5) is a constant voltage transformer-rectifier type welding machine. It provides volt-current characteristic curves that are essentially flat. This power source can be used with most GMAW (MIG) applications from thin sheet metal to heavy-gauge plate. FabWorld Operator's Manual Page 25 MOTOMAN Figure 3-5 Excel-Arc Controls 3.9.1 Main Power The Input Power switch (7) turns on the main power to the Excel-Arc unit.

FabWorld Operator's Manual Page 26 MOTOMAN 3.9.2 Volt / Amp Settings The Welding Voltage / Amperes Control (2) adjusts the welding output and open circuit voltage. The Volt / Amp Meter and Switch (3) display either DC voltage or DC current depending on the position of the switch. Refer to your Excel-Arc manual for additional information. 3.9.3 Terminal Connectors The two terminals on the front of the Excel-Arc power source serve as connection points for the welding leads. The Positive Terminal (4) connects to the positive welding lead (to the wire feeder). The Negative Terminal (5) connects to the negative welding lead (to the workpiece). 3.9.4 Local / Remote Operation The Local / Remote Output Control Selector Switch (6) sets the mode of operation for the power source. For FabWorld applications, this switch should be set to REMOTE. Refer to your Excel-Arc manual for additional information. 3.9.5 Feeder Control Receptacles The Feeder Control Receptacle Panel (8) located in the back of the power source provides connectors for use with remote voltage control applications. For FabWorld applications, the MRC connects to the 19-pin connector. 3.9.6 Circuit Breakers The Excel-Arc power source uses two 10-amp circuit breakers (9 and 10). One circuit breaker protects the 24 volt circuit; the other protects the 115 volt circuit. 3.9.7 AC Receptacles The Excel-Arc unit has two standard 115-VAC Receptacles (11). These provide auxiliary power at a maximum current of 10 amps. For applications using the water-cooled torch, the water circulator plugs into one of these receptacles. FabWorld Operator's Manual Page 27 MOTOMAN 3.10 WELDING EQUIPMENT In addition to the Excel-Arc power source, the FabWorld system provides a complete complement of arc welding equipment. In its standard configuration, the FabWorld system includes the following: • PWF4-600 wire feeder • Universal welding interface (UWI) • Either an air-cooled or water-cooled GMAW torch • RAM torch breakaway mount The following sections briefly describe each of the listed devices. Refer to your Motoman Robotic Arc Welding Manual for more detailed information. 3.10.1 PWF4-600 Wire Feeder The PWF4-600 wire feeder mounts on the robot arm. The 4-roll wire feeder provides reliable wire feeding at rates up to 600 IPM. An integral gas valve provides fast gas response time. The wire feeder has an inch forward button to help simplify setup and reduce change-over time. The PWF4-600 wire feeder uses interchangeable feed rolls to accommodate different types and sizes of wire. 3.10.2 Universal Welding Interface The universal welding interface (UWI) provides microprocessor control to the wire feeder and power source. It scales the signals from the MRC to the appropriate levels required for control of the welding components. It also provides isolation of the power source analog signals. 3.10.3 GMAW Torch The FabWorld uses either an air-cooled or water-cooled robotic/automatic GMAW torch. These are heavy-duty torches designed for quick replacement while requiring minimum robot reprogramming. The GMAW torch mounts on the end of the robot wrist. For applications that use the water-cooled torch, the FabWorld includes a suitable water circulator kit. 3.10.4 RAM Torch Breakaway Mount A Motoman RAM torch breakaway mount protects the robot, workpiece, fixture, and positioner. It provides multi-directional impact detection, including Z-axis collisions. The torch breakaway causes the robot to stop immediately upon impact. Keyed joints ensure accurate realignment of components. FabWorld Operator's Manual Page 28 MOTOMAN 3.11 SAFETY EQUIPMENT The FabWorld system incorporates a host of safety equipment. When all standard safety precautions are taken, the safety equipment helps to ensure safe operation of the robotic cell. The ANSI/RIA R15.06 Robot Safety Standard stipulates the user is responsible for safeguarding. Users are responsible for determining whether the provided safeguards are adequate for plant conditions. Users must also ensure that safeguards are maintained in working order. The FabWorld safety features include the following: 3.11.1 • Arc curtains • Safety fencing • Interlocked safety mats • Photo eyes • Zone ring monitor • Emergency stop (E-Stop) buttons Arc Curtains WARNING! Although the arc screens block dangerous arc radiation, you should not look directly at the arc during operation without protective eyewear! The FabWorld cell uses two different arc screens. The first set covers the safety fencing of the robotic cell. The second set mounts on posts located at the sides of each station. The cell has no fencing or arc screen at the openings of the separate stations (where the operator loads and unloads parts). Motoman recommends that the user provide portable arc screens that can be put in place to protect workers in the area against arc radiation. 3.11.2 Fencing The safety fencing provided with the FabWorld system encloses and defines the robotic cell. It forms a physical barrier to prevent entry into the robot envelope. 3.11.3 Safety Mats FabWorld Operator's Manual Page 29 MOTOMAN The safety mats provided with the FabWorld helps prevent serious injury to anyone entering the active welding station. Stepping on a mat while the robot is in Play mode and in the same zone causes an E-Stop. 3.11.4 Photo Eyes The through-beam photoelectric switch consists of two devices: a light sender and a light receiver. The separate construction permits scanning across large distances with a corresponding reserve capacity. Breaking the photo beam while the robot is in Play mode and in the same zone causes an E-Stop. 3.11.5 Zone Ring Monitor The zone ring monitor is a monitoring control that allows the operator to load and unload parts in any zone other than the active welding zone. The zone monitor works in conjunction with the safety mats and the photo eyes of the system. Entering the active welding zone while the robot is in Play mode causes an E-Stop condition to occur. 3.11.6 Emergency Stops In addition to the interlocking devices described above, the FabWorld cell has several strategically placed emergency stops (E-Stops). These are operator actuated devices that, when activated, immediately cause the system to shut down. The following is a list of their locations: • The MRC control panel has one E-Stop button. • The MRC programming pendant has one E-Stop button. • Each positioner operator station has one E-Stop button. The following actions also cause an E-Stop when the robot is in Play mode: • Breaking the photo eye light beams in an active zone. • Stepping on the safety mats in an active welding zone. • Insufficient air pressure in the multi-plane (tilt/rotate) positioner. FabWorld Operator's Manual Page 30 MOTOMAN 4.0 OPERATION This section provides operation instructions for the FabWorld system. Operation procedures include the following: • System start-up • Part setup • Normal operation • Fault recovery • System shutdown This section also includes several sample programs that demonstrate the proper format and instruction sequences for different operations.

FabWorld Operator's Manual Page 44 MOTOMAN NOTES FabWorld Operator's Manual Page 45 MOTOMAN 5.0 MAINTENANCE 5.1 PERIODIC MAINTENANCE For periodic maintenance procedures and schedules for the K6 robot, the K10 robot, and the MRC controller, refer to your K6 MRC Manipulator Manual or K10 MRC Manipulator Manual. For maintenance information regarding the multi-plane and rotary plane positioners, refer to your Aronson Manual. For maintenance information regarding the welding power source, refer to your Excel-Arc Owner's Manual. Table 5-1 provides a list of periodic maintenance to be performed on the FabWorld cell. Keep in mind that the maintenance intervals given serve as guidelines only. You should adjust the frequency of maintenance to suit your specific work conditions. WARNING! Do not use automotive antifreezes in the water circulator. Automotive antifreeze has stop leak additives that will clog the small GMAW torch water cooling ports. The additives will damage gaskets in the pump. Use Dynaflux Inc. Defense DF929 or equivalent Ethylene Glycol with fungus inhibitors and emulsion lubrication. CAUTION! Before performing maintenance on the wire cutter, be sure to turn off the air supply. FabWorld Operator's Manual Page 46 MOTOMAN Table 5-1 Periodic Maintenance Frequency Component Procedure As Required Torch Tender (optional) Refill anti-spatter container. Regularly Photo Eyes Clean the photo eye lenses with a soft clean cloth and nonsolvent cleaner. Regularly Safety Mats Sweep the tops and underneath the safety mats to remove debris. Make sure that the mats lay flat. Anything under the mats can cause them to actuate. Check the mats for tears, gouges, buckling, etc. Replace the mats if necessary. Daily Water Circulator Kit Check the fluid in the water (optional) circulator. Add fluid as required. Use only distilled water and approved antifreeze (Motoman Part Number 131224-1). Weekly Wire Cutter (optional) Clean the unit with detergent machine cleaner. Apply grease to the wire cutting mechanism through the grease zerk provided. 6 Months PWF4 Pancake Wire Feeder Annually Water Circulator Kit Flush the system completely. (optional) Refill as needed. FabWorld Operator's Manual Page 47 Clean feed roll grooves with industrial machine cleaner. Replace feed rolls as required.
