Select a mounting option Taper mount Interference fit Taper mount method Step 2 u Clean shaft taper and internal taper of RESM as recommended in the storage and handling section. A section u Insert the first screws: For RESM rings with, 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 Step 1 Alternative installation Will not correct eccentricity of the supporting shaft. For RESM rings with, 1 or 20 mounting holes, use 4 equally spaced M3 screws. NOTE: Do not lubricate screws. Recommended screw type M3 x 0.5: ISO 472/DIN 9 grade.9 minimum/ansi B18.3.1M. u Insert the screws so that the RESM 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.

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. NOTE: It may be necessary to loosen screws whilst tightening other screws. 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. NOTE: At this stage, the screws should only be lightly tightened (less than 0.5 Nm) to allow further final adjustment. TONiC RESM installation guide 7
Select a mounting option (continued) Taper mount method Step 5 Taper mount method Step 3 u u Insert the next screws: For RESM rings with, 9 or mounting holes, insert all the remaining M3 screws. For RESM rings with 1 mounting holes, insert 3 equally spaced M3 screws. For RESM rings with 18 mounting holes, insert equally spaced M3 screws. For RESM rings with 20 mounting holes, insert 8 equally spaced M3 screws (in four groups of two) between existing screws. 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.

Please contact your local representative for more details. Taper mount method Step 4 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. Interference fit method Mounting shaft specifications. DO DS NOTE: 417, 489 and 550 mm rings should be taper mounted only.

System connection Approved ESD precautions must be followed at all times during readhead and interface electrical connections. The readhead is connected to the Ti/TD interface via a small, rugged connector to allow for easy feedthrough during installation. Connecting the readhead u Remove the cover plate as shown (2 x M2.5 hex head screws). u Taking care not to touch the pins, plug the connector into the socket in the interface, ensuring correct orientation as shown. Disconnecting the readhead u Remove the cover plate on the interface (2 x M2.5 hex head screws). u Gently lever the connector PCB (on the end of the cable) out of the socket. Do not pull the cable to remove the connector. u Place the connector in an antistatic bag. u Refit the cover plate. u Refit the cover plate ensuring the cable ferrule is located in the recess on the inside and no wires are trapped under the cover plate. TONiC RESM installation guide 9
T20x1 readhead and RESM compatibility T20x1 readhead models are compatible with a range of RESM ring sizes. The optical configuration is optimised for the following conditions: Readhead model T2001 T2011 T2021 RESM diameter range >13 0 to 13 <0 Published performance specifications and operating tolerances only apply where the correct readhead model conforms to the RESM size range. Ensure readhead part number and RESM size range compatibility at the time of ordering and installation. Readhead mounting and alignment Mounting brackets The bracket must have a flat mounting surface and should enable conformance to the installation tolerances, allow adjustment to the rideheight of the readhead, and be sufficiently stiff to prevent deflection or vibration of the readhead during operation. Readhead setup Ensure that the scale, readhead optical window and mounting face are clean and free from obstructions. To set nominal rideheight, place the Green spacer with the aperture under the optical centre of the readhead to allow normal LED function during setup procedure. Adjust the readhead to maximise the signal strength and achieve a Green setup LED on the readhead (>70% signal) for a complete rotation. If a digital Ti/TD interface is used, aim for a Blue LED on the interface. NOTE: The readhead should be installed and setup with the AGC switched off (CAL LED off). When reinstalling, factory defaults should be restored. Readhead setup LED status Yaw 0 ±0.4 Green Orange Red Reference mark position Green spacer Optical centreline Roll 0 ±0.5 INTRAC reference mark is integrated in the scale, radially aligned with the centre of the mounting hole to the left of the Renishaw logo within ±0.5 mm.

System calibration Calibration is an essential operation that completes readhead setup, with the optimum incremental and reference mark signal settings stored in the readhead s nonvolatile memory. Before system calibration: u Clean the scale and readhead optical window (contamination around the reference mark may result in reference mark dephasing). u If reinstalling restore factory defaults. u Maximise the signal strength along full axis of travel. NOTE: CAL routine maximum speed <0 mm/s (all Ti/TD interface models). TD interface can be calibrated in either resolution. Step 1 Incremental signal calibration u Ensure Automatic Gain Control is switched off (CAL LED on readhead is not illuminated) before beginning calibration. u Press and release the CAL button on the end of the interface using a 2 mm allen key or similar tool. WARNING! Activating the CAL switch only requires 2.5 N force. Applying excess force may permanently damage the switch. u The CAL LED will now periodically singleflash to indicate that it is in incremental signal calibration mode. u Move the readhead along the axis, ensuring you do not pass the selected reference mark, until the CAL LED starts doubleflashing, indicating the incremental signal is now calibrated and the new settings are stored in the readhead memory. u The system is now ready for reference mark phasing. u For systems without reference mark, go to Calibration routine manual exit u If the system does not automatically enter the reference mark phasing stage (no doubleflashing of the CAL LED) the calibration of the incremental signals has failed. After ensuring failure is not due to overspeed (>0 mm/s), exit the calibration routine, restore factory defaults and check the readhead installation and system cleanliness before repeating the calibration routine. Step 2 Reference mark phasing u Move the readhead back and forth over the selected reference mark until the CAL LED stops flashing and remains off. The reference mark is now phased. u The system automatically exits the CAL routine and is ready for operation. u If the CAL LED continues doubleflashing after passing the chosen reference mark many times, it is not detecting the reference mark. Ensure that the correct readhead configuration is being used. Readheads can either output all reference marks or only output a reference mark where a reference selector magnet is fitted. Calibration routine manual exit u To exit the calibration routine at any stage press the CAL button. The CAL button will then stop flashing. u Release CAL button. u Check the Readhead mounting/installation and recalibrate the system. NOTE: System must be recalibrated after restoring factory defaults. Switching Automatic Gain Control (AGC) on or off AGC can be switched on or off via the interface. u Press and hold the CAL button on the interface for >3 seconds to switch AGC on or off. The CAL LED on the readhead will be illuminated when AGC is active. NOTE: The system must be calibrated before switching AGC on.
