About NEXLINE® Linear Motor Actuators: NEXLINE® is a patented high-force, ultra-high-precision linear motor actuator developed to bridge the gap between micro- and nanopositioning technology. The highly reliable, all-ceramic NEXLINE® drives have won a technology award from the semiconductor community and are ideally suited for static and dynamic high-precision positioning of high loads. PI currently offers 3 standard Nexline actuators (N-110, N-214, N-215) for closed- and open-loop operation with maximum loads up to 60 kg.
Controller Features Linearization, 24 Bit D/A Converters, Picometer Resolution
The new E-755 NEXLINE® motion controller combines sophisticated control algorithms, high-end 32-bit digital filters and output drivers with extremely low-noise, 24-bit D/A converters. In closed-loop operation, outstanding linearity, within 0.001% over the full travel range, is achieved by polynomial linearization.

Closed-Loop and Open Loop Operation, Dithering Mode
NEXLINE Controllers can be run in closed-loop and open-loop mode. They provide an input for the nanometer precision incremental linear encoders that are integrated in standard NEXLINE® actuators. Due to the low-noise, 24 bit D/A converters, the E-755 controllers can provide picometer level resolution in the highly-dynamic short-range / dithering mode that the actuators support.
Software Support
The E-755 controllers come with an extensive software package including LabVIEW drivers for simple and flexible automation of nanopositioning tasks.
