Newport updates XPS multi-axis controller

A Newport Spectra-Physics product story
Edited by the Engineeringtalk editorial team Jun 23, 2009

Newport Spectra-Physics will display its recently developed Hexapod six-axis micropositioning system at the Laser World of Photonics show.

The system is driven by six high-performance DC servo-motor driven LTA actuators that have been enhanced to specifically match the requirements of a Hexapod.

The Newport Hexapod features an anti-friction coated spherical joint that provides five-times the rigidity and twice the load capacity of other hexapods of a similar size.

The Newport Hexapod electronic controller is a version of the Newport XPS advanced multi-axis controller, which accurately masters the synchronised transformations from Cartesian input co-ordinates to the motion of the Hexapod legs.

The XPS also features instrument-grade I/Os, hardware-based input triggers, event triggers, high-speed on-the-fly data acquisition, fast TCP/IP communication and integrated TCL programming language for on-board processes.

All these features improve accuracy and throughput, simplifying the programmer's life.

The Hexapod XPS controller provides a freely definable virtual pivot point as a standard feature and offers more in relocating the pivot point and the entire co-ordinate system.

In addition, two user-definable co-ordinate systems are provided, called tool (moves with the Hexapod) and work (stationary co-ordinate systems).

Incremental displacements are possible in either one of these systems in user-friendly Cartesian co-ordinates, and a function call allows positions to be easily calculated from one system to the other.

These powerful functions provide a new method of mastering Hexapod motions without the need for complex external co-ordinate transformations.
