PI L.P. (Auburn, MA) introduced the E-755 NEXLINE® ultra-high-resolution motion controller that is designed to drive NEXLINE® linear motor actuators, enabling the combination of long travel ranges and picometer resolution. The E-755 features 32-bit digital filters, 24-bit DAC resolution, integrated piezo amplifiers, fully programmable low-pass and notch filters, and non-volatile user settings and last-position data. It can be run in closed-loop and open-loop mode and in closed-loop operation linearity is achieved by polynomial linearization. The controller comes with a software package that includes LabVIEW drivers for automation of nanopositioning tasks. The low-noise, 24-bit D/A converters enable the controllers to provide picometer-level resolution in the short-range/dithering mode supported by the actuators.
