Stage Controllers support 100 picometer command resolution.

Press Release Summary:

Nanopositioning stage controllers feature USB interface and 24-bit DA/AD converters to work with piezo nanopositioning systems from 1 mm and up. It also includes RS-232 interface and analog interface for compatibility with NI cards. Software libraries and GUIs provide support for LabView, Matlab, and text-based programming languages while programmable data tables allow random waveform generation. Products are available in 1-12 channels and in benchtop, rack-mount, and OEM card versions.

Original Press Release:

Nanopositioning Goes 24 Bit: USB Interface and High-Resolution DA/AD Converters

Auburn, MA, Piezo system specialist PI is switching to a new generation of 24-bit resolution, nanopositioning stage controllers. The new controllers will enable better than 100 picometers command resolution for even the latest generation, long-travel, piezo nanopositioning systems (1 mm and up), such as the PIHera(TM) series closed-loop flexure stages. The use of 24-bit converters represents more than 2 orders of magnitude improvement over the still widely used 16-bit converters.

USB Interface, 1 to 12 Channels, Many Variations

The new controllers feature a high speed USB interface and come in a variety of bench-top, rack-mount and OEM card versions from single-channel units for simple linear actuator applications, to multi-axis system controllers with 12 channels per rack.

Features and Advantages

  • Integrated USB Interface, 24 bit converters for higher position resolution.

  • Additional RS-232 interface for compatibility with industrial controllers

  • Extensive software libraries & GUIs; support for LabView, Matlab, text-based programming languages

  • Analog interface for compatibility with NI cards and analog control signals

  • Network capability with up to 12 channels for multiaxis positioning applications

  • Choice of position feedback sensors: capacitive for highest precision and piezoresistive / strain gauges for cost sensitive applications

  • Integrated servo controller with notch filter for higher bandwidth

  • User programmable data tables for random waveform generation

    Extensive Software Support, Hardware-Independent Command Set

    The new piezo controllers come with Windows installation software, DLLs and LabVIEW drivers. The extensive command set is based on the hardware-independent General Command Set (GCS), common to all PI micro & nanopositioning systems. GCS reduces the programming effort in the face of complex multi-axis positioning tasks or when upgrading a system with a different PI controller.
