Newport has introduced the XPS-DRVP1, an XPS-compatible driver card for the piezoelectric stack-based Nanopositioning line of sub-nanometre-resolution stages.

The XPS-DRVP1 complements the other XPS driver cards that are designed to drive the traditional DC- or stepper-motor micro-positioning products, enabling the control of almost all Newport motion products with the XPS controller.

Said to be straightforward to install, the XPS-DRVP1 eliminates the need for either an XPS pass-through card or an independent piezo-stack driver.

The company claims that the XPS-DRVP1 permits a wider variety of precision motion control positioning applications than was previously possible.

Beda Espinoza, product manager for Newport Motion, said: ‘Now customers have the ability to perform precise, fast positioning over long travel and finish their motion processes with ultra-precise sub-nanometre positioning resolution.

‘The XPS-compatible controller works with all “-D” versions of Newport’s Nanopositioners.

‘An erasable programmable read-only memory [EPROM] stores the stage parameters in the connector, which also has embedded ESP plug-and-play technology that auto-uploads the stage ID and all necessary stage settings to the XPS.

‘This facilitates setups to ensure that our customers are up and running in no time,’ added Espinoza.

The single-axis XPS-DRVP1 driver features 60mA peak current (operating from -10V to +130V) and has an internal loop rate of 4kHz.

For added flexibility, it can drive both open-loop and closed-loop Nanopositioning stages equipped with strain-gauge position sensors that offer dynamic performance similar to Newport’s NPC3 controller.
