- Page 13 The SH80 can be automatically removed and replaced on the probe body by using a SCP80/V mounted on an MRS or suitable extrusion. SH80's design makes it possible to dock into an SCP80 port which is aligned with any of the four sides of the SP80 probe. This enables the SCP80 / SCP80V system to be positioned to the rear, front, left or right of the CMM, or any combination of these.
- Page 14 The SH80K is a device with a kinematic location ball that allows you to power off the SP80 and SP80H probes and turn it back on without needing to re-home the probe.
- Page 15 SCP80 The SCP80 stylus changing port enables automation of SH80 interchange onto the SP80 probe. It does not require any electrical connection for operation, and it fits to the MRS / MRS2. This provides simple flexibility to incorporate as many ports as required, whilst optimising working volume.
- Page 16 SCP80V The SCP80V stylus changing port enables automation of SH80 changing operation with the SP80H and long, rear orientated styli with SP80. It does not require any electrical connection for operation, and it fits to any standard extrusion. This provides simple flexibility to incorporate as many ports as required, whilst optimising working volume.
- Page 17 IU80 interpolator unit The IU80 interpolator unit is a free-standing interface for the SP80 and SP80H. It is required for installations where the UCC S3 controller and UCC PI 80 interface are not used. The IU80 is connected to the probe by the machine cable. The output of the IU80 is then transferred either to the CC6, or alternatively to an OEM controller via a Renishaw supplied unterminated cable.
- Page 18 CC6 PCI counter card The Renishaw CC6 counter card is a 5 V 32 bit PCI card. The card can be used to integrate the Renishaw SP80(H) probe when used in conjunction with the Renishaw IU80 interpolator unit. The CC6 monitors the output of the probe via the IU80 and supplies the host PC with this information on request, via the PCI bus. The CC6 is small enough to fit neatly into a 5 V switching standard PCI slot inside the host PC without precluding the insertion of any other cards or impairing any required access to other components.
- Page 19 SP80 and SP80H user's guide www.renishaw.com Isolated optical metrology principle Using an isolated optical metrology principle, the probe directly measures the deflection of the whole mechanism, thus providing outstandingly accurate position sensing. The isolated optical metrology system can detect sources of variable error such as thermal and dynamic effects. By contrast, probes with displacement sensors mounted to stacked axes suffer from latency under changing inertial loads, and cannot detect thermal growth in their mechanisms.

CC6 counter card. NOTE: The SP80 and SP80H can be powered by either a connection to a Renishaw UCC S3 controller and UCC PI 80 interface, or an IU80 and CC6 counter card via a PC or an OEM specifically designed system. - Page 28 IU80 features and LEDs Signal interpolation The IU80 divides the 4 micron periodic signals produced by the SP80 by a factor of 200. This gives a system resolution of 20 nm for each probe axis. Error signal generation The IU80 monitors the signals received from the SP80 probe to ensure that each axis readhead is functional. In the event of probe cable damage or unreliable probe signals, an error signal is latched and provides an output via pin 4 of the 26-way connector.
- Page 29 SP80 LED control The SP80 probe has a tri-colour LED which can be controlled by the user to act as a visual aid for measurement applications. The LED can be set to red, green or orange depending on the following inputs to pins 9 and 10 of the 26‐way ‘D' plug.
- Page 30 SP80 / SP80H body The SH80 incorporates the male half of a magnetic kinematic joint that connects to the female half of the joint on the bottom of both the SP80 and SP80H probe body. The SH80 carries M5 styli, and has a 5-way centre design that can be rotationally adjusted for infinite angle position of the stylus.
- Page 31 SP80 and SP80H user's guide www.renishaw.com Mounting styli on the SH80 and styli orientation Mounting styli on the SH80 It is recommended that the SH80 is removed from the probe body when attaching styli. M5 stylus arrangements are directly screwed into the 5-way cube on the SH80. Where required, use step down adaptors to smaller thread styli, or select cubes and knuckles to create the required cluster.
