AUBURN, Mass., Oct. 2, 2009 – PI (Physik Instrumente) LP is switching to a new generation of 24-bit-resolution nanopositioning stage controllers that will enable better than 100-pm command resolution for the latest long-travel piezo nanopositioning systems of 1 mm and up. The use of 24-bit converters represents more than two orders of magnitude improvement over the widely used 16-bit ones.
The controllers feature 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 multiaxis system controllers with 12 channels per rack. They include 24-bit converters for higher position resolution and have an additional RS-232 interface for compatibility with industrial controllers.
Also included are analog-to-digital and digital-to-analog converters; extensive software libraries and GUIs; support for LabView, Matlab and text-based programming languages; an analog interface for compatibility with National Instruments’ cards and analog control signals.
They offer network capability with up to 12 channels for multiaxis positioning applications. Position feedback sensor choices include capacitive for high precision and piezoresistive/strain gauges for cost-sensitive applications.
The integrated servo controller has a notch filter for higher bandwidth, and user-programmable data tables provide random waveform generation.
The piezo controllers are supplied 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 of the company’s micro and nanopositioning systems. The GCS reduces the programming effort in the face of complex multiaxis positioning tasks or when upgrading a system with a different proprietary controller.
