These are found in separate sections in the User’s Guide and Product manual. The installation shall be made by qualified installation personnel and should conform to all national and local codes. When you have unpacked the robot, check that it has not been damaged during transport or while unpacking. Operating conditions: Ambient temperature + 5° to + 45°C (manipulator) Relative humidity Max. 95% at constant temperature Storage conditions: If the equipment is not going to be installed straight away, it must be stored in a dry area at an ambient temperature between -25°C and +55°C. When air transport is used, the robot must be located in a pressure-equalized area. The net weight of the manipulator is approximately 1950 kg. The control system weighs approximately 240 kg. Whenever the manipulator is transported, axis 2 must be bent backwards 30° and axis 3 must be moved down to a position against the rubber stops on axis 2. Product Manual IRB 640 3 Transporting and Unpacking Installation and Commissioning 1.1 Stability / risk of tipping When the manipulator is not fastened to the floor and standing still, the manipulator is not stable in the whole working area. When the arms are moved, care must be taken so that the centre of gravity is not displaced, as this could cause the manipulator to tip over. The following table shows the positions where there is a risk of tipping and refers to figures in chapter 3.8 in Product Specification IRB 640, for definition of position 0 and 5. Working area, position 0 load = 0 kg load = max no no yes no Working area, position 5 load = 0 kg load = max no yes = stable = risk of tipping 1.2 System diskettes The diskettes in the box, fixed to the shelf for the teach pendant, should be copied (in a PC) before they are used. Never work with the original diskettes. When you have made copies, store the originals in a safe place. Do not store diskettes inside the controller due to the high temperatures there. 4 Product Manual IRB 640 Installation and Commissioning On-Site Installation 2 On-Site Installation 2.1 Lifting the manipulator The following lifting instructions are valid for a “naked” robot. Whenever additional equipment is put on the robot, the centre of gravity can change and make lifting dangerous. Never walk under a suspended load. If the integrated lifting ears on the front cannot be reached, the manipulator must be reoriented to the sync position. The best way to lift the manipulator is to use lifting straps and a traverse crane. Attach the straps to the integrated lifting eyes on both sides of the frame (see Figure 2). The lifting strap dimensions must comply with the applicable standards for lifting. It is also possible to use two lifting devices (option) for use with a fork lift truck (see Figure 4). NB! The right lifting device, the robot seen from behind, must be removed before start-up, see Figure 1. Lifting device View from behind Figure 1 Lifting device that must be removed.

Use shims if necessary. The rest of the surface must be flat within ± 2 mm. Footprint diagram, see Figure 5. Floor mounted models can be tilted max. 5o. The levelness requirement for the surface is as follows: 0.5 Y ∅ 0.2 720 415.7 D=48(3x) D=32(3x) 100 ±0,5 Z X A 480±0.1 A 15 D=64 H9 (3x) +2 0 Support surface D=85 (3x) A-A Guide sleeve Figure 5 Bolting down the manipulator (dimensions in mm). The manipulator is fixed with three M30 bolts, tightened alternately. Suitable bolts: M30x160 8.8 Socket screw with washer Tightening torque: 1000 Nm Two guide sleeves can be added to two of the bolt holes, to allow the same manipulator to be re-mounted without program adjustment (see Figure 5). When bolting a mounting plate or frame to a concrete floor, follow the general instructions for expansion-shell bolts. The screw joint must be able to withstand the stress loads defined in Chapter 2.3 Stress forces . Product Manual IRB 640 9 On-Site Installation Installation and Commissioning 2.3 Stress forces 2.3.1 Stiffness The stiffness of the foundation must be designed to minimize the influence on the dynamic behaviour of the robot. For optimal performance the frequency of the foundation with the robot weight must be higher than 22 Hz. TuneServo can be used for adapting the robot tuning to a non-optimal foundation. 2.3.2 All versions Endurance load (In operation) Max. load (Emergency stop) Force xy ±12 000 N ±18 000 N Force z 21 000 ±5 500 N 21 000 ±10000 N Torque xy ± 32 000 Nm ±39 000 Nm Torque z ±6 000 Nm ±13 000 Nm Force xy and torque xy are vectors that can have any direction in the xy plane.

Product Manual IRB 640 11 On-Site Installation Installation and Commissioning 2.5 Manually engaging the brakes All axes come equipped with holding brakes. When the position of a manipulator axis needs to be changed without connecting the controller, an external voltage supply (24 V DC) must be connected to enable engagement of the brakes. The voltage supply should be connected to the connector at the base of the manipulator (see Figure 8). 0 V B14 +24 V B16 Figure 8 Connection of external voltage to enable engagement of the brakes. External power must be connected according to Figure 8. Incorrectly connected power can release all brakes, causing simultaneously movement of all axes. When the controller or the voltage device is connected, illustrated above, the brakes can be engaged separately by means of the push-buttons on the brake release unit on the exterior of the axis 3 gear box. The push-buttons are marked with the appropriate axis name. The names of the axes and their motion patterns are illustrated in Figure 9. WARNING: Be very careful when engaging the brakes. The axes become activated very quickly and may cause damage or injury. Axis 3 6 5 4 3 2 1 NB! Buttons 4 and 5 are not connected. Axis 2 Axis 6 Brake release unit Axis 1 Figure 9 The robot axes and motion patterns. 12 Product Manual IRB 640 Installation and Commissioning On-Site Installation 2.6 Restricting the working space When installing the manipulator, make sure that it can move freely within its entire working space. If there is a risk that it may collide with other objects, its working space should be limited, both mechanically and using software. Installation of an optional extra stop for the main axes 1, 2 and 3 is described below. Limiting the working space using software is described in the chapter System Parameters in the User’s Guide. 2.6.1 Axis 1 The range of rotation for axis 1 can be limited mechanically by fitting extra mechanical stop arms. Instructions for doing this are supplied with the kit. IMPORTANT! The mechanical stop pin and the extra moveable mechanical stop arm for axis 1 must absolutely be replaced after a hard collision, if the pin or arm has been deformed. Product Manual IRB 640 13 On-Site Installation 2.6.2 Installation and Commissioning Axes 2 and 3 The working range of axes 2 and 3 is limited by mechanical stops and can be reduced by adding fixed mechanical stops. The stops are mounted on the inside of the frame to each axis. Extra stops must be mounted in a row, starting at the fixed stop. Holes for extra stops Figure 10 Mechanically limiting axes 2 and 3. NB! The robot is always delivered with one extra mechanical stop mounted for axis 3. It is not allowed to remove it. 14 Product Manual IRB 640 Installation and Commissioning On-Site Installation 2.7 Mounting holes for equipment on the manipulator NB: Never drill a hole in the manipulator without first consulting maintenance staff or the design department at ABB Flexible Automation. 260 M10 (2x) through 80 130 M10 (4x) through 200 230 126 99 45 35 100 Limit for M10 surfaces M10 (2x) depth 25 Limit for M10 surfaces 411 60 69 220 486 Figure 11 Holes for mounting extra equipment (dimensions in mm). 30o D=10 H7 depth 10 8 M10 (6x) depth 18 D=80 H7 D=160 h7 60o D=125 F-F 8 Figure 12 The mechanical interface (mounting flange) ISO 9409 (dimensions in mm). 2.7.1 Quality of screws for fitting extra equipment When fitting tools on the manipulator’s mounting flange (see above), use only screws with quality of 12.9. When fitting other equipment, standard screws with quality 8.8 can be used. Product Manual IRB 640 15 On-Site Installation Installation and Commissioning 2.8 Loads It is important to define the loads properly (with regard to the position of centre of gravity and inertia factor) in order to avoid jolting movements and unnecessary stops due to overloaded motors. For more information see chapter 3.4 in Product Specification IRB 640 (Technical specification) for load diagrams, permitted extra loads (equipment) and their positions. The loads must also be defined in the software, see User´s Guide. 16 Product Manual IRB 640 Installation and Commissioning Product Manual IRB 640 On-Site Installation 17 On-Site Installation 18 Installation and Commissioning Product Manual IRB 640 Installation and Commissioning Customer connections on manipulator 3 Customer connections on manipulator The hose for compressed air is integrated into the manipulator.

If the fixed stop arm is bent, no attempt must be made to straightened it. 2. If the pin is bent, a collision between the swinging stop arm and the stop pin has probably occurred. A bent stop pin must always be replaced by a new one. 3. If any of the adjustable stop arms are bent, they must be replaced by new ones. Article number 14 Stop pin 3HAB 4082-1 Adjustable stop arm 3HAB 4533-3 (Option) Product Manual IRB 640 Maintenance 2.10 Changing the battery in the measuring system The battery to be replaced is located under the cover, in the front of the frame. (See Figure 9). The robot is delivered with a rechargeable Nickel-Cadmium (Ni-Cd) battery with article number 4944 026-4. The battery must never be thrown away, it must always be handled as hazardous waste. • Set the robot to the MOTORS OFF operating mode. (This means that it will not have to be coarse-calibrated after the change.) • Loosen the battery terminals from the serial measuring board and cut the clasps that keep the battery unit in place. • Install a new battery with two clasps and connect the terminals to the serial measuring board. • The Ni-Cd battery takes 36 hours to recharge; the mains supply must be switched on during this time and there must not be any interruptions in the power supply. Figure 9 The battery is located in the front of the frame. Alternative battery As an alternative to the Ni-Cd battery a lithium battery of primary type can be installed. The lithium battery needs no charging and for this reason there is a blocking diode which prevents charging from the serial measurement board. The benefit with a lithium battery is the extended service life, which can be up to 5 years, compared with a Ni-Cd battery’s max service life of 3 years. Two types of lithium battery are available: - a 3-cell battery, art.no. 3HAB 9999-1 - a 6-cell battery, art.no. 3HAB 9999-2 Product Manual IRB 640 15 Maintenance The service life of the lithium battery depends on how frequently the user switches off the power. The estimated max service life in years for the different types of lithium battery and the recommended exchange intervals are shown below: User type: Exchange 3-cell: Exchange 6-cell: 1. Vacation (4 weeks) power off every 5 years every 5 years* 2. Weekend power off + user type 1 every 2 years every 4 years 3. Nightly power off + user types 1 and 2 every year every 2 years * Because of material ageing the maximum service life is 5 years. Voltage of batteries, measured at power off: Min. Max. Ni-Cd 7.0 V 8.7 V Lithium 7.0 V - The battery is exchanged as described in the first section of this chapter, except for the fastening of the 3-cell battery on the board, see Figure 10. Clasps Connect the clasps together N.B. Tighten the band around the batteries before tightening the clasps.

640 Repairs General Description 1 General Description The industrial robot system IRB 640 comprises two separate units; the control cabinet and the mechanical unit. The service of the mechanical unit is described in this document. As regards service, the mechanical unit is divided into the following main parts: • Electrical System • Motor Units • Mechanical System The Electrical System is routed through the entire robot and consists of two major systems; power cabling and signal cabling. The power cabling feeds the robot axes' motor units. The signal cabling feeds the various controlling parameters like axis positions, motor revs, etc. The AC type Motor Units provide the motive power for the various robot axes via gears. Mechanical brakes, electrically released, lock the motor units when the robot is inoperative for more than 180 seconds. The Mechanical System has 4 axes, enabling the flexible robot motions. Axis 3 Axis 2 Axis 6 Axis 1 Figur 1 The robot axes and motion patterns. Product Manual IRB 640 3 General Description Repairs Axis No. 1 rotates the robot via a frame. Axis No. 2, which provides the lower arm´s reciprocating movement, is supported in the frame. The Lower Arm forms together with the Parallel Arm and the Parallel Bracket, a parallelogram against the Upper Arm. The Parallel Bracket is mounted in bearings in the Parallel Arm and in the Upper Arm. Axis No. 3 provides elevation of the robot's upper arm. Axis No. 6 is a turning motion. A connection is arranged for various customer tools at the front end of the wrist in the Turn Disc. The tool (or manipulator) can be equipped with pneumatic control via an external air supply. The signals to/from the tool can be supplied via internal customer connections. The Control Cabinet must be switched off during all service work on the robot! Before doing any work on the robot measurement system (measurement board, cabling), the accumulator power supply must always be disconnected. When service work is finished, the calibration position should always be checked with the system disc. The Brake Release Unit should be connected as indicated in Section 7, Installation and Commissioning, to enable movements of the axes. Special care must be taken when the brakes are operated manually. This applies particularly when the robot is started up, either for the first time or after a stoppage. The safety instructions in the Programming Manual must be complied with at all times. 4 Product Manual IRB 640 Repairs General Description 1.1 Document Guidance The subsequent chapters describe the type of service work that can be carried out by the Customer´s own service staff on site. Certain types of work, requiring special experience or special aids, are not dealt with in this manual. In such cases, the defective module or component should be replaced on site. The faulty item should be sent to ABB Flexible Automation for service. Calibration. Recalibration of the robot may have to be carried out after replacing mechanical unit parts or when the motor and feedback unit have been separated; or when a resolver error has occurred or the power supply between a measurement board and resolver has been interrupted. The procedure is described in detail in Chapter 9, Calibration. IMPORTANT! When work is done on the robot signal cabling, this may result in the robot moving to incorrect positions. After doing such work, it is important that the robot calibration position is checked as described in Chapter 9.5, Checking the calibration position. If a calibration fault is discovered, the robot must be recalibrated as described in Chapter 9, Calibration. Tools. Two types of tools are required for various service jobs involving dismantling; on the one hand, conventional tools like socket and ratchet spanners, etc.; on the other hand, special tools may be necessary, depending on what type of service is being carried out. The conventional tools are not dealt with in this manual, based on the assumption that the service personnel have sufficient technical basic competence. However, service work requiring the use of special tools is described in this manual. Foldouts. In the Spare Parts chapter of this manual, there are a number of foldouts illustrating the robot parts, intended to facilitate quick identification of both the type of service required and the composition of the various components. The parts are item numbered on the foldouts. The foldouts are referred to in the Manual text within “arrow heads” (< >) as exploded view numbers. Where reference is made to foldouts, other than those specified in the paragraph title, the foldout number is included in the item number reference, for example <5/19> or <10:2/5>, the digit(s) before the stroke referring to the foldout number. Numbers in brackets ( ) refer to figures in the text. The foldouts also include information such as article number, designation and relevant data. N.B. This manual is not to be considered as a substitute for a proper training course. This document is intended for use after the course has been completed. Product Manual IRB 640 5 General Description Repairs 1.2 Caution The mechanical unit contains several parts which are too heavy to lift manually. As these parts must be moved with precision during any maintenance and repair work, it is important to have a suitable lifting device available. The robot should always be switched to MOTORS OFF before allowing anyone to enter its working space. 1.3 Mounting Instructions for Bearings and Seals 1.3.1 Bearings 1. Let a new bearing remain in its wrapping until it is time for fitting, to avoid contamination of the bearing. 2. Ensure that all parts included in the bearing fitting are free from burrs, grinding waste and other contamination. Cast components must be free from foundry sand. 3. Bearing rings, inner rings and roller elements must under no circumstances be subjected to direct impact. Also, the roller elements must not be exposed to any stresses during the assembly work. Tapered Bearings 4. The bearing should be tensioned gradually until the recommended pre-tension is achieved. 5. It is important to note that the roller elements must be rotated a specified number of turns before pre-tensioning is carried out, and also rotated during the pre-tensioning sequence. 6. The above procedure must be carried out to enable the roller elements to adjust to the correct position against the race flange. Also, it is important that the bearing is properly aligned, as this will directly affect the lifespan of the bearing. Greasing Bearings 6 7. The bearing must be greased after fitting. The main reason for this is the requirement for cleanliness. 8. Grooved ball bearings should be filled with grease from both sides. 9. Tapered roller bearings and axial needle bearings shall be greased in the split condition. Product Manual IRB 640 Repairs General Description 10. The bearings must not be completely filled with grease. However, if space is available beside the bearing fitting, the bearing may be totally filled with grease when mounted, as surplus grease will be thrown out from the bearing when the robot is started up. 11. During operation, the bearing should be filled to 70-80% of the available volume. 12. Ensure that grease is handled and stored properly, to avoid contamination. 1.3.2 Seals 1. The commonest cause of leakage is incorrect fitting. Rotating Seals 2. The sealing surfaces should be protected during transport and mounting. 3. The seal should be kept in the original wrappings or be well protected. 4. Sealing surfaces must be inspected before mounting. If scratches or damage are found, that may result in future leakage, the seal must be replaced. 5. Seals should also be checked before mounting to ensure that: • there is no damage to the sealing edge (feel with a fingernail) • the seal is of the correct type (provided with cutting edge) • there is no other damage. 6. Grease the seal just before fitting it, but not too early as there is a risk of dirt and foreign particles adhering to the seal. The space between the dust tongue and sealing lip should be filled to 2/3 with grease. The rubber coated external diameter must also be greased. 7. The fitting of seals and gears must be carried out on clean workbenches. 8. Mount the seal correctly. If it is misaligned, there is a risk of leakage due to the pumping effect. 9. Always mount the seal with a mounting tool. Never hammer directly on the seal, as this may result in leakage. 10. Use a protective sleeve for the sealing lip during mounting, when sliding over threads, keyways, etc. Product Manual IRB 640 7 General Description Repairs Flange Seals and Static Seals 11. Check the flange surfaces. They must be even and free from pores. It is easy to check flatness using a gauge on the fastened joint (without sealing compound). 12. Differences in surface level or the presence of burrs due to incorrect machining are not permissible. If flange surfaces are defective, the parts must not to be used, because leakage could result. 13. The surfaces must be properly cleaned in accordance with ABB ROBOTICS PRODUCTS recommendations. 14. Distribute the sealing compound evenly over the surface, preferably with a brush. 15. Tighten the screws evenly when fastening the flange joint. O-rings 8 16. Check the O-ring grooves. The grooves must be geometrically correct and free from pores and contamination. 17. Check the O-ring with regard to surface defects, burrs, shape accuracy, etc. 18. Ensure that the correct O-ring size is used. 19. Tighten the screws evenly when assembling. 20. Defective O-rings and O-ring grooves must not be used. 21. Fitting defective parts will result in leakage. Grease the O-ring with lubricant before mounting. Product Manual IRB 640 Repairs General Description 1.4 Instructions for Tightening Screw Joints General It is of the utmost importance that all screw joints be tightened with the correct torque. Application The following tightening torques are to be used for all screw joints in metallic materials unless otherwise specified in the text. These instructions do not apply to screw joints comprising soft or brittle materials. For screws with a higher property class than 8.8, the data for 8.8 must be used unless otherwise specified. Screws treated with Gleitmo (lubricated) When handling screws treated with Gleitmo, protective gloves of nitrile rubber type should be used. Screws treated with Gleitmo can be unscrewed and screwed in again 3-4 times before the slip coating disappears. Screws can also be treated with Molycote 1000. When screwing in new screws that are not Gleitmo treated, these should first be lubricated with Molycote 1000 and tightened to the specified torque. Assembly Lubrication with molybdenum disulphide grease (Molycote 1000) should only be used when specified in the text. Screws lubricated with Molycote 1000 and then torque tightened, should also to be lubricated between the washer and the head of the screw. Screws with dimension M8 or larger should be tightened with a torque-wrench, if possible. Screws with dimension M6 or smaller may be tightened to the correct torque using tools without torque indication, by personnel with adequate mechanical training and instruction.

Product Manual IRB 640 41 Axis 6 42 Repairs Product Manual IRB 640 Repairs Motor units 8 Motor units 8.1 General Each manipulator axis is provided with a motor unit consisting of: - A synchronous AC motor - A brake unit - A feedback unit. A gear on the output shaft of the motor forms together with the gear on each axis, the complete gear unit. Dismounting/mounting of the gear unit is described in an earlier chapter of this manual. The electro-magnetic brake is built into the motor unit. The brake is released by a 24 V DC supply. For brake release see Section 7, Installation and Commissioning. The feedback unit consists of a resolver mounted on the motor shaft and is built into the motor unit in a similar way as the brake. Power and signal connections to the motor units are via separate cables between connections points inside the manipulator and each motor. The cables are connected to the motor units with connectors. - The feedback unit is fitted by the motor manufacturer and must never be separated from the motor. - The communication angle is + 90° (COMOFF=2048). The motors never need commutating. - The motor, resolver and brake is to be regarded as an replacement motor unit. Faulty motor units are repaired by the motor manufacturer at the request of the ABB Robotics service organisation. - The cable routing is shown in Figure 8. Note that the signal connection cable and the power connection cable must not be entwined. Signal connection Power connection Figure 8 Cable routing in the motor unit.

Gear reduction ratio 1/2/3 3HAB 8278-1 22 185 6 3HAB 5762-1 6 81 A check on the static brake torque for each motor unit can be done by applying a load on the moving arm or on the turning disc in some suitable way. When calculating the brake torque, the arm and gear reduction ratio must be taken into consideration. The coefficient of efficiency for the gear is assumed to be 1.0. 44 Product Manual IRB 640 Repairs Calibration 9 Calibration 9.1 General The robot measurement system consists of one feedback unit for each axis and a measurement board that continuously keeps track of the current robot position. The measurement board memory has a battery backup. Note! The accumulator unit will be fully recharged when the mains supply has been on for 36 hrs. without any power interruptions. If any of the resolver values are changed, the measurement system must be carefully calibrated (as described in Chapter 9.2, Calibration procedure). This happens when: - parts affecting the calibration position have been replaced on the robot. If the contents of the revolution counter memory are lost, the system needs to be roughly calibrated (as described in Chapter 9.4, Setting the calibration marks on the manipulator). This may happen when: - the battery is discharged. - a resolver error occurs. - the signal between a resolver and measurement board is interrupted. - a robot axis has been moved with the control system disconnected. 9.2 Calibration procedure The axes must be adjusted in increasing sequence, i.e., 1 - 2 - 3 - 5 - 6. 1. Position the manipulator approximately in calibration position 0 as shown Figure 11. 2. Select the MOTORS OFF mode. Axis 1 3. Remove cover plate on the reference surface on gearbox 1. 4. Attach the synchronisation fixture 6896 0011-YM to the flat surface and insert the corresponding measuring rod 6896 0011-YN in one of the three holes in the base. Turn the operating mode selector to MANUAL REDUCED SPEED. 5. Press the enable device on the programming unit and operate the robot manually with the joystick until the measuring rod is positioned within the flat surface on the calibration fixture’s elbow. Be careful! Risk of injury! Product Manual IRB 640 45 Calibration Repairs 6. Align the pin and tool with a sliding calliper. See Figure 9. Sliding calliper 6896 0011-YM MANIPULATOR Figure 9 Aligning the pin and tool with a sliding calliper for axis 1. Before calibrating axes 2, 3 and 6, calibrate the sensors against each other, using a reference plane surface, in the same direction. See Figure 10. 0000 Reference plane Sensor Figure 10 Calibrating the sensors. Axes 2, 3 and 6 7. Release the enabling device. 8.

Press the enabling device and operate the joystick manually in the directions shown in the figure on the previous page, until the digital levelling gauge indicates zero. The gauge should read 0 ±12 increments. (0.3 mm/m). The reason why the calibration position is always adjusted in the directions shown in the figure, is that the friction and gravity forces then work together against the direction of the movement. In this way adjustment is simplified. 48 Product Manual IRB 640 Repairs Calibration 14. Move the sensor and continue the calibration procedure for the other axes. 15. When all the axes have been adjusted, the resolver values are stored by executing the following commands on the teach pendant. 16.

Product Manual IRB 640 51 Calibration Repairs 9.4 Setting the calibration marks on the manipulator When starting up a new robot, you may receive a message telling you that the manipulator is not synchronised. The message appears in the form of an error code on the teach pendant. If you receive such a message, the revolution counter of the manipulator must be updated using the calibration marks on the manipulator. See Figure 17. Examples of when the revolution counter must be updated: - when the battery unit is discharged - when there has been a resolver error - when the signal between the resolver and the measuring system board has been interrupted - when one of the manipulator axes has been manually moved without the controller being connected. It takes 36 hours’ operation to recharge the battery unit without any power interruptions. If the resolver values must be calibrated, this should be done as described in the chapter on Repairs in the IRB 640 Product Manual. WARNING Working in the robot work cell is dangerous. Press the enabling device on the teach pendant and, using the joystick, move the robot manually so that the calibration marks lie within the tolerance zone (see Figure 22). Note that axis 6 does not have any mechanical stop and can thus be calibrated at the wrong faceplate revolution. When all axes have been positioned as above, the values of the revolution counter can be stored by entering the following commands on the teach pendant: 1. Press the Misc. window key (see Figure 18). 7 4 1 1 2 P1 8 5 2 0 9 6 3 P2 P3 Figure 18 The Misc. window key from which the Service window can be selected 52 Product Manual IRB 640 Repairs Calibration 2.

Save the system parameters on a floppy disk. 54 Product Manual IRB 640 Repairs Calibration 9.5 Checking the calibration position There are two ways to check the calibration position; both are described below. Using the diskette, Controller Parameters: Run the program \ SERVICE \ CALIBRAT \ CAL 640 on the diskette and follow the instructions displayed on the teach pendant. When the robot stops, switch to MOTORS OFF. Check that the calibration marks for each axis are at the same level, see Figure 17. If they are not, the setting of the revolution counters must be repeated. Using the Jogging window on the teach pendant: Open the Jogging window and choose running axis-by-axis. Using the joystick, move the robot so that the read-out of the positions is equal to zero. Check that the calibration marks for each axis are at the same level, see Figure 17. If they are not, the setting of the revolution counters must be repeated. 9.6 Alternative calibration positions Before it can be calibrated in one of the two alternative positions, the robot must have been calibrated with calibration equipment at calibration position 0 for all axes (the robot is delivered with calibration position 0). See Figure 23. Cal.pos. 2 +90o Left (1.570796) Y Cal.pos. 0 X Right (-1.570796) Cal.pos. 1 -90o Figure 23 Calibration positions 0, 1 and 2 (Normal, Right and Left). Note! If the final installation makes it impossible to reach the calibration 0 position, an alternative calibration position must be set before installation. Product Manual IRB 640 55 Calibration Repairs 1. Run the calibration program CAL64 on system disk IRB 2 (SERVICE.DIR\ CALIBRATE.DIR). Select Normal position, check the calibration marks for each axes. 2. Run the calibration program again and select the desired calibration position (Left or Right), see Figure 23. 3. Change to the new calibration offset for axis 1, as follows: • Select the window SERVICE; • View: Calibration; • Calib: Calibrate; • Select axis 1 (no other axes) • Then confirm by pressing OK two times. 4. Change to the new calibration offset on the label, located on the frame to the left of motor axis 1 (remove the cover between axes 2 and 3). The new calibration offset values can be found as follows: • Select the window SYSTEM PARAMETERS; • Types: Motor; • Select axis 1; • Press Enter • Note the Cal offset value. 5. Change to the new calibration position on axis 1, as follows: • Select the window SYSTEM PARAMETERS; • Topics: Manipulator; • Types: Arm; • Select axis 1; • Change Cal pos to 1.570796 or -1.570796 depending on selected calibration position. The angle is in radians, see Figure 23. 6. Restart the robot by selecting File: Restart. 7. Move the sync.plate, on the base, for axis 1 to its new position. 8.
