PI Intros Next Gen Nanopositioning Controllers
New generation of nanopositioning controllers.
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 (1mm and up), such as the PIHera 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.

The new controllers have a high-speed USB interface and come in a variety of benchtop, 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.

The controllers provide: integrated USB interface, 24-bit converters for higher position resolution; additional RS-232 interface for compatibility with industrial controllers; extensive software libraries and 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 multi-axis 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. 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 and 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.
