CNC Controllers


OPEN-XS is the flexible, powerful and cost-effective entry level system of the OSAI CNC OPENcontrol family. Based on Intel Atom 1.6 GHz CPU, OPEN-XS is able to manage up to 2 processes (each one executing an ISO program) and up to 8 simultaneously interpolated axes. OPEN-XS is a modular system that offers both a solution for the control of servo-drives and I/O modules distributed on a digital fieldbus and also for controlling analog axes and integrated I/O.

Thanks to its characteristics, OPEN-XS allows obtaining high finishing in workpiece machining and optimization in working centers management:


  • Gantry and dual axes management
  • Look-ahead with 256 pre-calculated blocks
  • Velocity Feed Forward (VFF)coverxs
  • Jerk control using advanced algorithms
  • Management of tool magazine, tool life, random tool, multi-pocket tool
  • Multi-axis electronic CAM
  • Cross Compensation

The system can be completetly customized through a graphical HMI software and an embedded PLC offering:

  • Multi-tasking real time execution
  • Up to 250 tasks with 10 priority levels
  • Task cycle time with 2ms minimum scheduling
  • More than 450 predefined functions

Two different OPEN-XS models, based on the same control unit, allow the management of digital servo drives controlled by

  • the new Mechatrolink III protocol
  • the EtherCAT protocol whether based on CANopen
