Newport has launched the XPS-DRVP1, an XPS-compatible driver card for the piezoelectric stack-based nanopositioning line of sub-nanometre-resolution stages for motion control positioning applications.
The XPS-DRVP1 is said to complement the other XPS driver cards designed to drive the traditional DC or stepper motor micro-positioning products, allowing control of almost all of Newport's motion products with the XPS controller.
It is said to be convenient to install, and eliminates the need for either an XPS pass-through card or an independent piezo-stack driver.
The XPS-DRVP1 permits a wider variety of precision motion control positioning applications than was previously possible.
Customers now 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 that also has embedded ESP 'plug-and-play' technology that auto-uploads the stage ID and all necessary stage settings to the XPS.
This facilitates set-ups to ensure customers are up and running quickly.
The single-axis XPS-DRVP1 driver features 60mA peak current (operating from -10V to 130V), with 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 with dynamic performance similar to Newport's NPC3 controller.
