Newport introduces piezo driver for XPS controller/driver

Jan. 31, 2011
Newport’s XPS-DRVP1 drive module is designed to control piezoelectric stack-based NanoPositioning products.


Newport Corporation (Irvine, CA, USA), a provider of laser and photonic solutions, introduces the XPS-DRVP1, an XPS-compatible driver card for the piezoelectric stack-based NanoPositioning line of sub-nanometer resolution stages. The XPS-DRVP1 complements 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. Convenient to install, the XPS-DRVP1 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 and positioning applications than was previously possible.

According to Beda Espinoza, product manager for Newport Motion, “Now customers have the ability to perform precise, fast positioning over long travel and finish their motion processes with ultra-precise sub-nanometer 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 our customers are up and running in no time.”

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 gage position sensors with dynamic performance similar to Newport’s NPC3 controller.
