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--81465EN--1/02 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 1. SAFETY PRECAUTIONS SAFETY PRECAUTIONS B--81465EN--1/02 (9) When adjusting each peripheral device independently, be sure to turn off the power of the robot. Limit switch for the safety gate Panel board EAS1 EAS11 EAS2 EAS21 Note) Fig.1.1 Safety Fence and Safety Gate 5 Terminals FENCE1 and FENCE2 are on the PC board in the operator panel. Fence circuit is a safety stop circuit. 1. SAFETY PRECAUTIONS 1.1.1 Operator Safety SAFETY PRECAUTIONS B--81465EN--1/02 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 Panel board EES1 EES11 EES2 EES21 Note) Connect to EES1 and EES11, EES2 and EES21. Fig.1.1.1 Connection Diagram for External Emergency Stop Switch 6 B--81465EN--1/02 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). The teach pendant supplied by FANUC is provided with a teach pendant enable switch and a deadman switch in addition to the EMERGENCY STOP button. The functions of each switch are as follows. EMERGENCY STOP button : Pressing this button stops the robot in an emergency, irrespective to the condition of the teach pendant enable switch. Deadman switch : The function depends on the state of the teach pendant enable switch. When the enable switch is on -- Releasing the finger from the dead man switch or holding the deadman switch strongly stops the robot in an emergency. When the enable switch is off -- The deadman switch is ineffective. NOTE The deadman switch is provided so that the robot operation can be stopped simply by releasing finger from the teach pendant or holding the deadman switch strongly in case of emergency. The R--J3iB has adopted a 3--position deadman switch as an RIA--specification teach pendant. Pressing the 3--position deadman switch halfway makes the robot operable. Releasing the finger from the deadman switch or holding the deadman switch strongly causes the robot to enter the emergency stop state. 7 1. SAFETY PRECAUTIONS SAFETY PRECAUTIONS B--81465EN--1/02 (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 EAS1 and EAS11, EAS2 and EAS21 of the controller is invalidated. In this case, it is possible for an operator to enter the fence during teach operation without making the robot in the emergency stop condition. In other words, the system understands that the combined operations of pressing the teach pendant enable switch and pressing the deadman switch indicates the start of teaching. The teach pendant operator should be well aware that the safety gate is not functional under this condition and bear full responsibility to ensure that no one enters the fence during teaching. (5) When entering the robot work area, the teach pendant operator 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 remote switch on the operator’s panel. Teach pendant enable switch Remote condition Teach pendant Operator panel Peripheral devices On Independent Allowed to start Not allowed Not allowed Off Local Not allowed Allowed to start Not allowed Off Remote Not allowed Not allowed Allowed to start (6) To start the system using the operator panel, make certain that nobody is in the robot work area and that there are no abnormal conditions in the robot work area. (7) 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. 8 B--81465EN--1/02 SAFETY PRECAUTIONS 1. SAFETY PRECAUTIONS (8) While operating the system in the automatic operation mode, the teach pendant operator should leave the robot work area. 1.1.3 Safety During Maintenance For the safety of maintenance personnel, pay utmost attention to the following. (1) Except when specifically necessary, turn off the power of the controller while carrying out maintenance. Lock the power switch, if necessary, so that no other person can turn it on. (2) When disconnecting the pneumatic system, be sure to reduce 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--81465EN--1/02 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--81465EN--1/02 SAFETY PRECAUTIONS 1. SAFETY PRECAUTIONS 1.3 SAFETY OF THE ROBOT MECHANISM 1.3.1 Precautions in Operation 1.3.2 Precautions in Programming 1.3.3 Precautions for Mechanisms (1) When operating the robot in the jog mode, set it at an appropriate speed so that the operator can manage the robot in any eventuality. (2) Before pressing the jog key, be sure you know in advance what motion the robot will perform in the jog mode. (1) When the work areas of robots overlap, make certain that the motions of the robots do not interfere with each other. (2) Be sure to specify the predetermined work origin in a motion program for the robot and program the motion so that it starts from the origin and terminates at the origin. Make it possible for the operator to easily distinguish at a glance that the robot motion has terminated. (1) Keep the work area of the robot clean, and operate the robot in an environment free of grease, water, and dust. 11 1. SAFETY PRECAUTIONS SAFETY PRECAUTIONS B--81465EN--1/02 1.4 SAFETY OF THE END EFFECTOR 1.4.1 Precautions in Programming (1) To control the pneumatic, hydraulic and electric actuators, carefully consider the necessary time delay after issuing each control command up to actual motion and ensure safe control. (2) Provide the end effector with a limit switch, and control the robot system by monitoring the state of the end effector. 12 B--81465EN--1/02 1.5 SAFETY IN MAINTENANCE SAFETY PRECAUTIONS 1. SAFETY PRECAUTIONS (1) Never enter the robot work area while the robot is operating. Turn off the power before entering the robot work area for inspection and maintenance. (2) If it is necessary to enter the robot work area with the power turned on, first press the EMERGENCY STOP button on the operator panel. (3) When replacing or reinstalling components, take care to prevent foreign matter from entering the system. When replacing the parts in the pneumatic system, be sure to reduce the pressure in the piping to zero by turning the pressure control on the air regulator. (4) When handling each unit or printed circuit board in the controller during inspection, turn off the power of the controller and turn off the circuit breaker to protect against electric shock. (5) 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. (6) Before restarting the robot, be sure to check that no one is in the robot work area and that the robot and its peripheral devices are all in the normal operating state. 13 1.

(Corrective action) Turn on the circuit breaker. Breaker (Check 2) Check whether the LED (PIL: green) on the power supply unit is on. (Corrective action) If the LED is not on, 200 VAC is not supplied to the power supply unit. It is likely that fuse F1 in the power supply unit has blown. -- If 200 VAC is not supplied: Find the cause by referencing the general schematic diagram presented in the appendix. -- If 200 VAC is supplied: Find the cause of the blown fuse. Fuse F1 is in the power supply unit. Before you start troubleshooting, turn off the circuit breaker. a) If fuse F1 has blown: -- See Corrective action (1). b) If fuse F1 has not blown: -- Replace the power supply unit. (Corrective action(1)) Causes of blown fuses F1 and corrective action a) Check whether the unit and printed--circuit board connected to the connectors CP2 and CP3 in the power supply unit are abnormal, by referencing the general schematic diagram presented in the appendix. b) Short-circuit in the surge absorber VS1 VS1 is inserted to absorb surge voltage between input lines. If the surge voltage is excessive or sustained, excessively high voltage is applied to VS1 and a failure occurs in the short-circuit mode, causing F1 to blow. If a short-circuit occurs in VS1, and there is not a spare part, the system is permitted to operate without VS1. In this case, however, obtain and install a new VS1 as soon as possible. VS1 ordering number: A50L-2001-0122#G431k c) Short-circuit of diode stack DB1 d) The secondary power supply module is faulty : If one of the causes (b) to (c) above is detected, replace the power supply unit with a spare unit.

(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) Make sure that the CP2 and CRM73 of the E--stop unit and the servo amplifier CNMC2 and CNMC3 are connected tightly. (Action 2) Check whether an outage has occurred on an 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, servo--off input, or door switch).

(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 CRR38A or CRR38B 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 servo amplifier. (Action 6) Check disconnection of motor power cable (RM1, RM2). (Action 7) Replace the motor.

The fault condition should reset. If the controller is still faulted with additional servo--related errors, cold start the controller. It might be necessary to remaster the robot. (27) SRVO--041 SVAL2 MOFAL alarm (Group : i Axis : j) (Explanation) The servo value was too high. (Action) Cold start the controller. (28) SRVO--042 MCAL alarm (Group : i Axis : j) (Explanation) This alarm means that the contacts of the magnetic contactor have stuck to each other. The alarm condition occurs if the magnetic contactor turns out to be already on when an attempt is made to turn it on. The alarm condition is detected between the time contact sticking occurs and the time an attempt is made to turn on the magnetic contactor. (Action 1) Check the magnetic contactor, and replace it if necessary. If the contacts of the magnetic contactor have stuck to each other, turn off the circuit breaker. If the power is switched off without turning off the circuit breaker, the servo amplifier may get damaged, because the stuck contacts keep three--phase 200 V applied to the servo amplifier.

TROUBLESHOOTING MAINTENANCE B--81465EN--1/02 Servo amplifier Main board E--stop unit Fig.3.5 (28) SRVO--042 MCAL alarm (29) SRVO--043 SVAL1 DCAL alarm (Group : i Axis : j) (Explanation) The regenerative discharge energy was too high to be dissipated as heat. (To run the robot, the servo amplifier supplies energy to the robot. When going down the vertical axis, the robot operates from the potential energy. If a reduction in the potential energy is higher than the energy needed for acceleration, the servo amplifier receives energy from the motor. A similar phenomenon occurs even when no gravity is applied, for example, at deceleration on a horizontal axis. The energy that the servo amplifier receives from the motor is called the regenerative energy. The servo amplifier dissipates this energy as heat. If the regenerative energy is higher than the energy dissipated as heat, the difference is stored in the servo amplifier, causing an alarm.) (Action 1) This alarm may occur if the axis is subjected to frequent acceleration/deceleration or if the axis is vertical and generates a large amount of regenerative energy. If this alarm has occurred, relax the service conditions. (Action 2) Check fuse FS3 in the servo amplifier. If it has blown, remove the cause, and replace the fuse. One of the probable causes of a blown fuse is a ground fault in the servo amplifier for auxiliary axis. (Action 3) Make sure that the servo amplifier CRR63A, CRR63B and CRR63C are connected tightly, then detach the cable from CRR63A, CRR63B and CRR63C connector on the emergency stop board, and check for continuity between pins 1 and 2 of the cable--end connector. If there is no continuity between the pins, replace the regenerative resistance. 58 MAINTENANCE B--81465EN--1/02 (Action 4) 3.

If the resistance is not 9--16Ω, replace the regenerative resistor. Replace the servo amplifier. (Action 5) Servo amplifier Regenerative resistor Fig.3.5 (29) SRVO--043 SVAL1 DCAL alarm 59 3. TROUBLESHOOTING MAINTENANCE B--81465EN--1/02 (30) SRVO--044 SVAL1 HVAL alarm (Group : i Axis : j) (Explanation) The DC voltage (DC link voltage) of the main circuit power supply is abnormally high. (Action 1) Check the three--phase input voltage at the servo amplifier. If it is 253 VAC or higher, check the line voltage. (If the three--phase input voltage is higher than 253 VAC, high acceleration/deceleration can result in this alarm.) (Action 2) Check that the load weight is within the rating. If it is higher than the rating, reduce it to within the rating. (If the machine load is higher than the rating, the accumulation of regenerative energy might result in the HVAL alarm even when the three--phase input voltage is within the rating.

TROUBLESHOOTING (31) SRVO--045 SVAL1 HCAL alarm (Group : i Axis : j) (Explanation) Abnormally high current flowed in the main circuit of the servo amplifier. (Action 1) Disconnect the Robot connection cable (Motor power) from the servo amplifier. (Action 2) Disconnect the Robot connection cable (Motor power) from the servo amplifier connector (CNJ**), and check the insulation of each Robot connection cable (Motor power) (U, V, or W) and the GND line. If there is a short--circuit, the motor, robot interconnection cable, or intra--robot cable is defective. Check them and replace them if necessary. (Action 3) Disconnect the Robot connection cable (Motor power) from the servo amplifier connector (CNJ**), and measure the resistance between the U and V, V and W, and W and U with a ohmmeter with a very low resistance range. If the resistances at these three places are different from each other, the motor, robot interconnection cable, or intra--robot cable is defective. Check each item in detail and replace it if necessary. Servo amplifier Fig.3.5 (31) SRVO--045 SVAL1 HCAL alarm 61 3. TROUBLESHOOTING MAINTENANCE B--81465EN--1/02 (32) SRVO--046 SVAL2 OVC alarm (Group : i Axis : j) (Explanation) This alarm is issued to prevent the motor from thermal damage that might occur when the root meant square current calculated within the servo system is out of the allowable range. (Action 1) Check the operating conditions for the robot and relax the service conditions. (Action 2) Check each phase voltage of the three--phase input power (200 VAC for the servo amplifier. If it is 170 VAC or lower, check the line voltage. (Action 3) Replace the servo amplifier. (Action 4) Check the robot connection cable (RM1, RM2). If any problems are found in the cables, replace the cables. (Action 5) Replace the motor. Servo amplifier Fig.3.5 (32) SRVO--046 SVAL2 OVC alarm 62 3. TROUBLESHOOTING MAINTENANCE B--81465EN--1/02 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 OVC Overcurrent alarm Servo software Detection section 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. 63 3. TROUBLESHOOTING MAINTENANCE B--81465EN--1/02 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. The relationship between the OVC and OVL alarms is shown in Fig 2. Current Protection area for the motor and servo amplifier Protection by the OVL Limit current Protection by the OVC Rated continuous current Time Fig.2 Relationship between the OVC and OVL alarms NOTE The relationship shown in Fig. 2 is taken into consideration for the OVC alarm.

WARNING Before you start to replace a unit, turn off the control unit main power. Also keep all machines in the area of the control unit switched off. Otherwise, you could injure personnel or damage equipment. 164 B--81465EN--1/02 MAINTENANCE 7. REPLACING A UNIT 7.1 REPLACING THE PRINTED--CIRCUIT BOARDS 7.1.1 Replacing the Backplane Board (Unit) CAUTIONS When you replace printed--circuit boards, observe the following cautions: 1 Keep the control unit power switched off. 2 When you remove a printed--circuit board, do not touch the semiconductor devices on the board with your hand or make them touch other components. 3 Make sure that the replacement printed--circuit board has been set up appropriately. (Setting plug etc.) 4 If the backplane board, power supply unit, or main board (including cards and modules) is replaced, it is likely that robot parameters and taught data are lost. Before you start to replace these components, save a backup copy of the robot parameters and taught data to a memory card, floppy disk, or any other external memory device. 5 Before you disconnect a cable, note its location. If a cable is detached for replacement, reconnect it exactly as before. When replacing the backplane board, do so together with the plastic rack. (1) Detach the cables from the power unit and boards on the backplane board. CAUTION When you remove the main board, be sure that the battery is good (3.1--3.3VDC) and it is installed correctly. USE STATIC PROTECTION. (2) Remove the power unit and boards from the rack. (See Section 7.1.2.) (3) Detach the grounding cable from the backplane unit. (4) Loosen the retaining screws in the upper section of the rack. Remove the retaining screws from the lower section of the rack. (5) Side rack up and out. (6) To replace the backplane and rack, reverse steps (1) -- (6). CAUTION There is a possibility of data loss when a backplane-mounted printed circuit board is replaced. Be sure to back up all program and setup data on a floppy disk before proceeding. 165 7. REPLACING A UNIT MAINTENANCE B--81465EN--1/02 Fig.7.1.1 Replacing the Backplane Board 7.1.2 Replacing the Power Unit and Printed--Circuit Boards on the Backplane Unit The backplane unit incorporates the power unit, main board, and option boards. There are two types of option boards: Full--size board and mini--size board. A full--size board occupies one slot. A mini--size board uses part of a full--size board. CAUTION Before starting replacement, turn off the control unit main power. The main board is equipped with battery--backed memory devices for holding robot parameters and taught data, for example. When the main board is replaced, the data in the memory devices is lost. (1) Detach the cable from the power supply unit or the printed--circuit board, whichever is to be replaced. (2) Pinch the barbed handles on the upper and lower sections of the board to unlatch it, then pull it toward you. (3) Place the replacement board on the rail in the appropriate slot of the rack, then push it in gently by the handles until it is latched. (4) There are two rails in the main board SLOT (slot 1). When inserting the main board, align it to the right--side rail. (5) There are two rails in slots 3 and 5 (slots for a full--size option board). When you insert a full--size option board, align it to the left--side rail. 166 B--81465EN--1/02 7.

REPLACING A UNIT MAINTENANCE B--81465EN--1/02 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 main board. The power to the SRAM memory is backed up by a lithium battery mounted on the front panel of the main 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 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 main 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 main board. First unlatch the battery, remove it from the battery holder, and detach its connector. 196 B--81465EN--1/02 MAINTENANCE 7. REPLACING A UNIT Battery latch Lithium battery Battery connector (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. 197 III CONNECTIONS CONNECTIONS B--81465EN--1/02 1 1.

Teach pendant Teach pendant connection cable Fig.3.2.2 Teach Pendant Cable 207 3. ELECTRICAL CONNECTIONS 3.2.3 Connecting the Input Power CONNECTIONS B--81465EN--1/02 Considering the robot power capacity and the circuit breaker capacity, connect the power supply whose voltage conforms to the installation conditions to the terminal located above the circuit breaker. Provide a class--D or better ground. The resistance to the ground must not exceed 100Ω. Be sure to ground the work table or jig used by an arc welding robot or the like so that it can handle a large current. Use a thick wire to withstand the maximum current used. Selection of an input transformer tap is necessary depending on the input voltage. The tap is set to the specified voltage before shipment. However, check it referring to section 6.2 in “Maintenance” before supplying power (before the breaker switch is turned on). The motor is driven by the PWM inverter system using a power transistor bridge. If the servo amplifier is used without a transformer, a high-frequency leakage current flows through the stray capacitance between the ground and the motor coils, power cable, and amplifier. This might cause the leakage-current circuit breaker or leakage-protection relay installed in the path of the power supply to cut out. Use the following leakage current circuit breaker for inverters to prevent incorrect operation. Example of Leakage Current Circuit Breaker for Inverters Manufacture Type Fuji Electric Co., Ltd.

Make sure that network wiring is sufficiently separated from power lines and other sources of electrical noise such as motors, and ground each of the devices as necessary. Also, a high and insufficient ground impedance may cause interference during communications. After installing the machine, conduct a communications test before you actually start operating the machine. We cannot ensure operation that is influenced by network trouble caused by a device other than the main board. 275 4. PERIPHERAL DEVICE, ARC WELDING, AND END EFFECTOR INTERFACES 4.9.2.1 Connection to Ethernet CONNECTIONS B--81465EN--1/02 The main board is provided with a 10/100 BASE--T interface. Prepare a hub for connecting the Ethernet board to the Ethernet trunk. The following shows an example of a general connection. S S S R--J3iB Some devices (hub, transceiver, etc.) that are needed for building a network do not come in a dust--proof construction. Using such devices in an atmosphere where they are subjected to dust or oil mist will interfere with communications or damage the Ethernet board.

PERIPHERAL DEVICE, ARC WELDING, AND END EFFECTOR INTERFACES Even if the grounding conditions on the machine are satisfied, electrical noise from the machine sometimes enters the communications line and causes communications interference depending on the installation conditions and the peripheral environment of the machine. To prevent the entry of such electrical noise, separating and insulating the machine from the Ethernet trunk cable and the personal computer effectively reduces the influence of electrical noise. The following figure shows an example of such a connection. Electrically separated by 10/100 BASE--T cable connection Large--scale Network Electrically separated by 10/100 BASE--T cable connection Small--scale Network 281 4. PERIPHERAL DEVICE, ARC WELDING, AND END EFFECTOR INTERFACES CONNECTIONS B--81465EN--1/02 NOTE 1 The ground between the PC/Trunk line side and machine system side must be separated. If it is impossible to separate the ground because there is only one grounding point, connect the ground cable for each system to the grounding point independently. (Refer Fig.1) The resistance for grounding must be less than 100--ohm (Class 3). The thickness of the ground cable is the same as the thickness of AC power cable or more. At least thickness of 5.5mm2 is necessary. 2 Please use the HUB that has unshielded interface connector. FANUC recommends the HCN--7500 (Hitachi--Densen LTD) or equivalent. 3 There is the possibility that noise makes the obstacle of communication even if the ground is separated using the 10/100 BASE--T. In the case of using the Ethernet board under the worst environment, please separate between the PC/Trunk line side and machine system side completely using the 10/100 BASE--FL (Optical fiber media).

SPECIFICATIONS OF PERIPHERAL DEVICE INTERFACE All process I/O printed boards have a jumper to set the common voltage of input signals to 0 V or 24 V. The system automatically adjusts the polarity by software according to the status of this pin. Therefore, you can operate the system without being concerned about the setting of the common voltage. To ensure safety, the common reference voltage of the following four signals, is remains at +24V. *IMSTP *HOLD *SFSPD CSTOPI 319 B. SPECIFICATIONS OF PERIPHERAL DEVICE INTERFACE APPENDIX B--81465EN--1/02 B.3 I/O SIGNALS B.3.1 This section describes the specifications of each input signal. Input Signals (1) Instantaneous stop signal (input) *IMSTP Effective Function : At any time : Use the normally-closed switch because it is a reverse signal. The system turns off power to the servo unit when the *IMSTP is open (turned off). This signal has the same effect as that of the emergency stop signal, but it is controlled by software. For this reason, use the emergency stop external interface on the emergency stop control board for wiring of the emergency stop signal. Do not use *IMSTP. (2) Alarm release signal (input) FAULT RESET Effective Function : In the alarm status : The FAULT RESET signal releases the alarm status. If the servo unit has been turned off, it also turns on the unit. At the same time, the alarm display on the teach pendant (the top line) is cleared. Description : This signal releases only the alarm status. It does not re-start execution of the program. The robot will keep running if the signal is triggered “ON” during operation. (3) Hold signal (input) *HOLD Effective Function : At any time : Use the normally-closed switch because it is a reverse signal. The *HOLD signal has the same function as the hold button on the operator panel. It halts the current program and stops the operation of the robot. While this signal is being input, the held signal (output) HELD is turned on and the robot cannot be operated. 320 APPENDIX B--81465EN--1/02 B. SPECIFICATIONS OF PERIPHERAL DEVICE INTERFACE (4) Start signal (input) START Effective Function : When the command acceptance enabled signal (output) CMDENBL is turned on. See the description of CMDENBL in Section B.3.2 (1) for details. : This input signal starts the selected program at the falling edge when the signal is turned off after being turned on. Its function differs according to the setting of parameter $SHELL_CFG.$CONT_ONLY. - If parameter $SHELL_CFG.$CONT_ONLY is set to DISABLED, the START signal starts the program which has been selected from the teach pendant. By default, the program starts from the current cursor position. - If parameter $SHELL_CFG.$CONT_ONLY is set to ENABLED, the START signal only resumes the execution of the temporarily held program. To execute an inactivated program from the start, input the PROD_START signal. (5) Cycle stop signal (input) CSTOPI Effective Function : At any time : - If parameter $SHELL_CFG.$USE_ABORT is set to DISABLED, the CSTOPI signal releases the program from the wait status caused by an RSR. It does not stop the execution of the current program and allows it to continue processing (by default). - If parameter $SHELL_CFG.$USE_ABORT is set to ENABLED, the CSTOPI signal immediately cancels the execution of the current program. The program returns to the status in which it was before execution, and the information for the subprogram to return to the main program is lost. At the same time, this signal also releases the program from the wait status caused by RSR. (6) Enabling signal (input) ENBL Effective Function : At any time : If the ENBL signal is turned off, the operation of the robot or the activation of a program is inhibited, and the execution of the current program is suspended. 321 B. SPECIFICATIONS OF PERIPHERAL DEVICE INTERFACE APPENDIX B--81465EN--1/02 (7) Safety speed signal (input) *SFSPD Effective Function : At any time : - Use the normally-closed switch because it is a reverse signal. Usually this switch should be connected to safety fence. It must be set normally on. - Since the *SFSPD signal is counted as a remote condition, such input signals as RSR and START to the peripheral device interface cannot take effect unless this signal is turned on. - If this signal is turned from on to off during robot operation, the execution of the current program is suspended. At the same time, the overriding value is switched to a preset value (parameter $SCR. $FENCEOVER.) - As long as this signal is off, the overriding value cannot be increased beyond the preset value ($SCR.$SFJOGOVLIM: For jog, $SCR. $SFRUNOVLIM : For test execution.) (8) Robot service request signal (input) RSR1/RSR2/RSR3/RSR4 Effective Function : When the command acceptance enabled signal (output) CMDENBL is turned on. See the description of CMDENBL in Section B.3.2 (1) for details. : - The user can choose between RSR and PNS (optional), although they cannot be used simultaneously. - Four input signals, RSR1 to RSR4, are used. - If a signal is input to an RSR input, a specified. program is started. The program number can be set by a menu. - If another program has already started processing, the newly activated program enters the wait status. As soon as the current program terminates, the waiting program starts processing. - By using an RSR instruction, each RSR in a program can be enabled or disabled. - A menu is provided to register the program number of a specified program when each RSR is input. (Refer to the application manual for details of the menu). 322 B--81465EN--1/02 APPENDIX B. SPECIFICATIONS OF PERIPHERAL DEVICE INTERFACE - When an RSR is input, the program whose program name consists of the specified program number plus a base value is started. For exam ple, if a signal is input to RSR2 when program number 23 is registered in RSR2, the program to be started is the one with the program name calculated from the expression RSR + (RSR2 program number + base number), i.e., RSR0123. The base number is stored in parameter $SHELL_CFG.$JOB_BASE, and can be changed in a program with a parameter instruction. (For example, $SHELL_ CFG. $JOB_BASE =100). In this way, the combination of programs which can be started by RSRs can be changed. - Whether the system should output an acknowledge signal to an RSR can be selected from the menu. If so specified, a pulse is output from the signal corresponding to the RSR, one of signals ACK1 to ACK4, when the input of the RSR is accepted. From the same menu, the width of the pulse can also be specified. It is possible to accept other RSRs while outputting an acknowledge signal. - Input of a CSTOPIT signal can clear the program queue waiting for execution after acceptance of RSRs. (9) PNS/PNSTROBE (input) Signal name : PNS : Program number select PNSTROBE: Strobe input for PNS Effective : When the command acceptance enabled signal (output) CMDENBL is turned on. See the description of CMDENBL in Section B.3.2 (1) for details. Function : - The PNS/PNSTROBE signal selects whether the RSR function is used or the PNS function (optional) is used. If the PNS function is enabled, the RSR function cannot be used. - The eight signals PNS1 to PNS8 are used to specify a program at the instant the strobe signal PNSTROBE rises. - A menu is provided to specify the information about PNS. 323 B. SPECIFICATIONS OF PERIPHERAL DEVICE INTERFACE APPENDIX B--81465EN--1/02 If a number other than zero is entered to PNS input, a program is selected whose program number is the entered value plus the base number. For example, if the PNS value is 23, the program to be started has the program name calculated from the expression PNS + (entered PNS value + base number), i.e., PNS0123. If zero is entered to PNS input, it is cleared as if no selection has been made. - A PNS signal, which can only select a program, cannot execute the selected program. The execution of the selected program can only be started after input of automatic operation start signal PROD_START. - For safety, the selected program cannot be changed from the teach pendant unless PNSTROBE is turned off. - If a program is selected by PNS, the program number is output to selected program number signal (output) SNO, and a pulse is output to program selection acknowledge signal SNACK. Using these signals, peripheral devices can confirm the correct program has been selected. For the timing of these signals, see the sections describing SNO and SNACK. - The following operations are effective for the program selected by PNS. You can: · Start up a program by input of automatic operation start signal PROD_START · Restart the program that has been suspended. Inputting the START signal restarts the program selected by PNS when $SHELL_CFG.$CONT_ ONLY is set to ENABLED. · Input of CSTOPI cancels execution of the pro-grams selected by PNS when $SHELL_CFG.$USE_ ABORT is set to ENABLED. (10) Automatic operation start signal (input) PROD_START Effective Function : When the command acceptance enabled signal (output) CMDENBL is turned on. See the description of CMDENBL in Section B.3.2 (1) for details. : This input signal executes the selected program at the falling edge when the signal is turned off after being turned on. 324 B--81465EN--1/02 B.3.2 Output Signals APPENDIX B. SPECIFICATIONS OF PERIPHERAL DEVICE INTERFACE This section describes the specifications of output signals for the peripheral device interface. (1) Command acceptance enabled signal (output) CMDENBL Turned on : When the remote conditions are satisfied and the system is not in the alarm status Turned off : When the remote conditions are not satisfied or the system is in the alarm status The remote conditions are satisfied when all of the following are satisfied. - The teach pendant is in the DISABLED status. - The remote switch on the operator’s panel is set to REMOTE side. - Parameter $RMT_MASTER is set to 0 (external interface). - Signal *SFSPD is set to on, or in the normal status. (2) System ready signal (output) SYSRDY Turned on : When power is applied to the motor of the robot. Turned off : When power is not applied to the motor of the robot. (3) Program run signal (output) PROGRUN Turned on : When the program is being executed. Turned off : When the program is not being executed. (4) Held signal (output) HELD This signal is used to check the status of the hold input. Turned on : When the hold button (or input) is being pressed down (or turned on). Turned off : When the hold button (or input) is not being pressed down (or is turned off). (5) Program paused signal (output) PAUSED This signal is used together with output signal PROGRUN to determine whether a program can be restarted while it is being held. Turned on : When a program is held and has not been restarted yet. While this signal is on, the program can be restarted and retains information such as that to return from a subprogram to the main program. Turned off : When a program is being executed or is ready to start. If signal PROGRUN is on, the program is being executed. If signal PROGRUN is off, the program has not been executed and can be started from this status. (6) Alarm status signal (output) FAULT Turned on : When the system is in the alarm status (or an alarm which can stop a program execution is detected.) The indicator lamp does not go on in warning. Turned off : When the alarm status is released by an alarm release operation. 325 B. SPECIFICATIONS OF PERIPHERAL DEVICE INTERFACE APPENDIX B--81465EN--1/02 (7) Reference point signal (output) ATPERCH Turned on : When the robot is in the reference position specified in the parameter. (the reference point No.1 in reference point setup screen.) Turned off : When the robot is not in the reference position specified in the parameter. (the reference point No.1 in reference point setup screen.) Up to three reference positions can be specified, but this signal is output when the robot is in the first reference position. For the other two reference positions, general-purpose signals can be assigned to output as such. (They can be set from the setup screen.) (8) Teach pendant enabled signal (output) TPENBL Turned on : When the teach pendant is enabled. Turned off : When the teach pendant is disabled. (9) Battery alarm signal (output) BATALM Turned on : When the voltage of the battery for the CMOS memory backup drops below the reference. Turned off : When the voltage of the battery for the CMOS memory backup is at the normal level. (10) Operating signal (output) BUSY Turned on : When a program is being executed or is being processed from operation panels such as the teach pendant. (This has the same function as that of the BUSY lamp on the teach pendant.) Turned off : When a program is not being executed nor is being processed from operation panels such as the teach pendant. 326 B--81465EN--1/02 APPENDIX B. SPECIFICATIONS OF PERIPHERAL DEVICE INTERFACE (11) RSR acknowledge signals (output) ACK1/ACK2/ACK3/ACK4 These signals are used together with the RSR function. They can be specified to be enabled or disabled from the RSR setup menu. Turned on : When one of the signals from RSR1 to RSR4 is input and accepted. A pulse whose width is specified from the menu is output to acknowledge the signal. Turned off : Normally. Since these signals are always output as pulses, they are normally in the off status. The following chart shows the timing of the RSR input and ACK output. CMDENBL (O) (The remote conditions need to be satisfied.) RSR1 (I) The maximum delay is 32 msec. ACK1 (O) (The width of the pulse is set in the parameter.) RSR2 (I) ACK2 (O) RSR3 (I) ACK3 (O) RSR4 (I) ACK4 (O) * Other RSR signals can be accepted even when the ACK signal is being output. 327 B. SPECIFICATIONS OF PERIPHERAL DEVICE INTERFACE APPENDIX B--81465EN--1/02 (12) PNS acknowledge signal (output) SNO/SNACK These signals are used together with the PNS function. Turned on : Whenever the PNS function is enabled. The selected program number is displayed in binary code (SN01 to SN08) on the teach pendant. If the number cannot be represented as an eight-bit number, it becomes zero. After selecting a program by PNS, a pulse is output from signal SNACK as a part of the PNS operation. The width of the pulse can be specified from the menu. See the timing chart below. CMDENBL (O) (The remote conditions need to be satisfied.) PNS1-8 (I) PNSTROBE (I) Detection and processing of PNSTROBE by software. (A value is input.) (A strobe is input for PNS.) (PNS is read within a maximum of 32 msec after PNSTROBE is turned on.) SNO1-8 (O) SNACK (O) PROD_START (I) (Program execution starts within 32 msec.) PROGRUN (O) 328 B--81465EN--1/02 APPENDIX B. SPECIFICATIONS OF PERIPHERAL DEVICE INTERFACE B.4 SPECIFICATIONS OF DIGITAL INPUT/OUTPUT B.4.1 Overview B.4.2 Input/Output Hardware Usable in the R-J3iB Controller This section describes the external specifications of digital and analog input/output in the R--J3iB controller. The R--J3iB 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 can use a total of up to 512 I/O points. The R--J3iB 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. 329 B. SPECIFICATIONS OF PERIPHERAL DEVICE INTERFACE APPENDIX B--81465EN--1/02 B.4.3 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 eight inputs and eight 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. 330 B--81465EN--1/02 C APPENDIX C. POWER DISTRIBUTION CIRCUIT DIAGRAM POWER DISTRIBUTION CIRCUIT DIAGRAM 331 C.

OPTICAL FIBER CABLE D APPENDIX B--81465EN--1/02 OPTICAL FIBER CABLE The R--J3iB uses fiber optic cables for communication between the main board and servo amplifiers. Observe the following cautions when handling these fiber optic cables. Handle fiber optic cables with utmost care, especially when installing the unit. (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.D(a) Protection of electrical/optical conversion module and fiber optic cable (when not in use) 338 D. OPTICAL FIBER CABLE APPENDIX B--81465EN--1/02 (2) Fiber optic cable D Although the reinforcing cover of the external optical cable has sufficient mechanical strength, be careful not to drop heavy objects on the 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 Diameter of cable with reinforced cover : 7.6 mm Tensile strength : Cable with reinforced cover :75 kg Fiber optic cord :7 kg per cord Between fiber optic cord and connector : 2 kg Minimum bending radius of fiber optic cord :25 mm Minimum bending radius of cable with reinforced cover : 50 mm Bending resistance (cable with reinforced cover) : 10 million bending cycles at room temperature (when the bending radius is 100 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.D(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 Fix the reinforcing cover by using a cable clamp, as shown in Fig. D(c), to prevent the weight of the fiber optic cable from being applied directly to the connecting part of the optical connector. 339 D. OPTICAL FIBER CABLE Optical connector APPENDIX Part of optical fiber cord B--81465EN--1/02 Part of reinforcing cover Bending radius of 25 mm or more (Make the bending radius as large as possible.) Cable clamp (Don’t clamp tight) Bending radius of 50 mm or more (Make the bending radius as large as possible.) Fig.D(c) Fixing the cable with a clamp D Any superfluous portion of the cable might be wound into a loops. Should this prove necessary, make sure the diameter of each loop is at least 150 mm (for an external cable). Winding the cable into smaller loops can produce sharp curves that exceed the specified bend radius limit. Such bending can result in transmission loss, ultimately leading to a communication failure. D When using a nylon band (cable tie) as a cable clamp, follow the instructions given below. Also, take care not to apply a bending force to one particular part of the cable when fixing it with a clamp. Failing to clamp the cable correctly might cut or damage it. External cable : Do not clamp the uncovered portion of the cable with a nylon band. When clamping the cable by the reinforcing cover, the clamping force is not an important factor to consider. However, ensure that the clamping force is as small as possible to ensure that the reinforcing cover is not deformed by the clamping. If possible, the clamping force should be 5kg (111bs) or less. 340 E E.
