The REVO-2 head and CMM system are operated through UCCserver which uses I++DME command protocol to communicate between the system application software and the UCC S5.

Full 5-axis scanning capability is achieved through interaction between the UCC S5, the REVO-2 and the SPA3, to co-ordinate all the motion and metrology aspects across the three CMM axes and the two head axes.

Head comms signal booster box installation

When using the Renishaw high-speed communications cable (orange cable) with Renishaw's 5-axis products, the maximum permissible cable length is 25 m. Where runs of greater than 25 m are needed between the machine controller and probe head, a head comms signal booster (HCSB) must be inserted. One HCSB is required for each additional 25 m of cable run.

The HCSB is powered from the machine cable so does not require an additional power supply. It simply connects between two machine cables as shown in the diagram below and can be attached to a suitable part of the machine structure if required.

Cable connections

The cable connection to the head uses a standard 15-way high-density D connector. The cable should be connected and terminated as detailed below. It is mandatory that the Renishaw universal machine cable is used.

Various lengths of cable are available and include pre-crimped options for ease of installation.

The following image shows the pin numbers for each connector end view of the Renishaw universal machine cable.
