Features

  • Up to four CMM axes can be handled by the UCC BI
  • Up to five CMM axes can be handled by a dual UCC BI system.
  • The UCC BI can automatically adjust the supply voltage to encoder readheads (to compensate for long scale cables)
  • Some 3rd party temperature compensation boxes can be interfaced to the UCC BI using the RS232 interface
  • Probe interface (PICS)
  • MCU interface
  • Supporting incremental and absolute encoders
  • CMM machine input / output, including:
    • Air solenoid
    • Brakes (for each axis)
    • Z-axis crash status
    • Travel limit warnings (both inner and outer limits for each axis)
    • Air status
    • 13 un-committed I/O (6 input and 7 output) that can be customised by the user
