A section u Insert the first screws: For RESA rings with 6, 9 or 18 mounting holes, use 3 equally spaced M3 screws. B section Notes Not applicable Recommended for all installations Enables simplest adjustment. Offers highest accuracy. Enables eccentricity to be compensated. Offers excellent mechanical stability against thermal cycling, shock and vibration. Minimises cost of substrate preparation. Taper mount method Mounting shaft specifications Alternative installation Will not correct eccentricity of the supporting shaft. When using a RESOLUTE ETR the hub should be made of a material with a CTE of between 14 and 18 µm/m/ C. For more information on mounting the ring when using ETR please contact your local Renishaw representative. DT 1* Step 1 7 min 15 ±0.2 For RESA rings with 12, 16 or 20 mounting holes, use 4 equally spaced M3 screws. NOTE: Do not lubricate screws. Recommended screw type M3 x 0.5: ISO 4762/DIN 912 grade 10.9 minimum/ansi B18.3.1M. u Insert the screws so that the RESA is loosely connected to the shaft, then roughly align the ring by eye and touch. u Lightly tighten the screws. Use a Dial Test Indicator (DTI) to check the radial displacement at the screw locations. NOTE: Disregard the radial displacement between the screw locations. DTI Use a DTI with low exertion force to avoid scratching the scale surface. A DTI with a ruby ball stylus is recommended as a further precaution against scratches. *Allow 2 mm for 417 mm, 489 mm and 550 mm rings only Recommended taper roundness Recommended taper diameter (DT) u Adjust the screws to reduce the range of radial displacement. When adjusting, identify the screw location with the lowest radial displacement and tighten that screw, aiming for the average of the highest and lowest indicator readings. u Repeat this process until the DTI readings are within ±5 µm at the screw locations.

10 RESA Select a mounting option (continued) Taper mount method Step 5 Taper mount method Step 3 Taper mount method Step 4 u Insert the next screws: For RESA rings with 6, 9 or 12 mounting holes, insert all the remaining M3 screws. For RESA rings with 16 mounting holes, insert 3 equally spaced M3 screws. For RESA rings with 18 mounting holes, insert 6 equally spaced M3 screws. For RESA rings with 20 mounting holes, insert 8 equally spaced M3 screws (in four groups of two) between existing screws. u As described in Step 2, adjust all the screws inserted thus far, so that the radial displacement at each screw location is within ±5 µm. u Again, at this stage, the screws should only be lightly tightened (less than 0.5 Nm). NOTE: You may notice that the torque required to achieve the radial displacement tolerance will be slightly higher during step 3 than during step 2. This is normal. u Insert screws into the remaining mounting holes. Diameter (mm) Interference fit method Mounting shaft specifications.

Applies to A and B section rings. DO Recommended torque range (Nm) to to DS u Rotate the RESA ring, measuring the radial displacement at all of the screw locations. u Tighten the screw with the lowest radial displacement so that it matches the average radial displacement, whilst ensuring the maximum torque specified in the table is not exceeded. u Again, rotate the RESA ring and re-check the radial displacement at all of the screw locations, tightening the screw with the lowest radial displacement so that it matches the average. u Repeat this process until the radial displacement at all of the screw locations is within ±3 µm and that all screw torques are within the specified range. u Excessive tightening of screws can have a small effect on accuracy. Please contact your local representative for more details. NOTE: 417, 489 and 550 mm rings should be taper mounted only.

12 REXA Installation REXA should be flange mounted onto a flat surface, this eliminates all installation errors except eccentricity, which can be compensated using twin readheads. u Although taper mounting is best for thin cross-section rings, it is not suitable for thick cross-section REXA rings. u The REXA ring should be flange mounted onto a flat surface to minimise 2-per-rev distortion. u Some eccentricity of the ring is acceptable because it will be compensated by the use of twin readheads. u To avoid distorting the scale, the REXA should not be interference fitted. Mounting Step 2 u Clean the mounting face on the lower side of the REXA. Clean the mating surface on the mounting shaft. u Place the REXA onto the mounting shaft, then insert four off M5 screws with flat washers into the four screw holes by the fiducial marks. NOTE: Do not lubricate screws. Recommended screw type M5 x 0.8: ISO 4762/DIN 912 grade 10.9 minimum/ansi B18.3.1M. DO NOT tighten the screws at this point simply engage the threads ensuring that the heads do not touch the ring. Dimple or slot indicates fiducial mark NOTE: If using REXA with RESOLUTE ETR please contact your Renishaw representative. DO NOT INTERFERENCE FIT u Set up a Dial Test Indicator (DTI) to measure the run-out on the REXA ring. Shaft preparation Step 1 u NOTE: At this stage the ring is not firmly fixed, so to avoid causing the ring to shift position, rotate the ring slowly and smoothly. There is a mounting face on the lower side of the REXA ring. A flat surface should be prepared on the mounting shaft to match. The total axial run-out of the mounting surface should be better than 10 µm. N x M5 x 0.8 x 10 deep (<D1-0.75) A 0.01 A D4 u Where the DTI shows the lowest radius reading, gently tap the opposite side of the ring on the edge using a rubber mallet, until the DTI reading is approximately at the mid point of the run-out. u Now find the new lowest radius reading and again tap the opposite side of the ring with a rubber mallet until the DTI reading is at the mid point of the run-out. Use a DTI with low contact force to avoid scratching the scale surface. A DTI with a ruby ball stylus is recommended as a further precaution against scratches. D4 D2 Ø 0.2 A D1 u Continue this process until the run-out of the ring is approximately 30 µm ( inches). This is the initial adjustment. Now adjust to 10 µm at the fiducial points (see overleaf). For dimensions D1, D2, D3, D4 and number of holes N, please refer to ring drawing. D3 10

13 REXA Installation (continued) Mounting Step 3 Adjust ring position until the DTI (dial test indicator) reading at these points agrees to 10 µm. Slot fiducial Alternative method -using adjustment screws It is essential that 4 adjustment screws are used, aligned to the 4 fiducial points (indicated by a slot or dimple mark machined into the front face of the ring). IMPORTANT: To achieve the highest accuracy, the ring must not be distorted. When adjusting the ring position using adjustment screws, always work in opposing pairs, loosening one screw before tightening the other. Once the ring has been set to 10 µm in one plane, loosen both those adjustment screws before adjusting the other plane. For ease of adjustment, 4 off M5 screws with washers should be inserted into the ring and tightened finger-tight. These mounting screws should be fitted in the bolt holes aligned to the 4 fiducial marks. Mounting Step 4 Slot fiducial Take run-out measurements at the opposing fiducial points and centre the ring in that plane to within 10 µm. Next, centre the ring in the other direction to within 10 µm in the same way. Note that the run-out at the slots does not have to equal the run-out at the dimples. Finally, re-check the original plane. Note that 52 mm and 57 mm rings have dimple marks only, so select diametrically opposed dimples as adjustment points. Once the ring is set in both planes fit the remaining M5 screws and torque to 4 Nm. Now adjust the ring position until the DTI (dial test indicator) reading at these points agrees to 10 µm. Dimple fiducial Dimple fiducial Mounting Step 5 u Re-check the run-out at the two slot fiducial points, to ensure the run-out at the two slot points is still better than 10 µm. Adjust if necessary. u Gradually tighten the 4 screws, a quarter-turn at a time so as to avoid moving the position of the ring. Finally, insert the remaining M5 screws and torque all the screws to 4 Nm. u Re-check the run-out at the two slot fiducial points, then at the two dimple fiducial points. The run-out values at the slot fiducial points do not have to match the run-out values at the dimple fiducial points. If the ring has moved position outside the 10 µm limit, the screws must be loosened and the ring adjusted. 11

22 Siemens DRIVE-CLiQ dual head installation Accuracy The dual head interface is designed for use with two RESOLUTE readheads and REXA ring only and compensates for the effect of bearing wander and eliminates all odd error harmonics including eccentricity. However, even error harmonics such as ovality remain. This results in high angular accuracy to ± 1 arc second, as shown in the accompanying table. REXA diameter 100 mm Total installed accuracy (with 2 readheads) ±1 arc second 75 mm ±1.5 arc second 57 mm ±2 arc second For optimum accuracy performance, the readheads should be diametrically opposite each other so that the optical centre lines are 180 apart. However if this is not possible due to mounting constrictions, or for partial arc applications, the readheads should be mounted as close to this as possible; please contact your local Renishaw representative to find out what accuracy you can expect if this is the case. Electrical connections For high speed applications, it is recommended to use similar cable lengths for each readhead to ensure the readings are simultaneous and achieve the highest accuracy. The DRIVE-CLiQ cable is a proprietary part and is not supplied by Renishaw plc. Readhead Inner shield Interface output For readheads (RH1 and RH2) mounted such that the angle between them is θ.

Connect both readheads to dual head interface and connect interface to controller RH2 Output Supply power to the controller and interface, adjust each readhead such that both readheads have good signal levels around the ring (Green or Blue indication). The dual head DRIVE-CLiQ interface takes simultaneous readings from both readheads and calculates the mean of them. The output is therefore at an angle of θ/2 and is in the position shown when the scale is orientated with increasing count as shown. Acknowledge any errors on the controller that may have occured during installation. 20
