PI is switching to a new generation of 24-bit resolution, nanopositioning stage controllers.

The controllers will enable better than 100pm command resolution for 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 two orders of magnitude improvement over the 16-bit converters.

The 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 include: 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; analogue interface for compatibility with NI cards and analogue 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; and hardware-independent command set.

The piezo controllers come with Windows installation software, DLLs and Labview drivers.

The 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 for complex multi-axis positioning tasks or when upgrading a system with a different PI controller.

Physik Instrumente

PI is a global manufacturer of high precision positioning systems and products based on piezo technology. Used in markets as diverse as biotechnology, semiconductor, defence and astronomy, PI’s products work to improve the speed and precision of many cutting edge processes. Actuators, sensors and positioning systems with either sub-micron or nanometre level precision; many customised for the end user, are included in the product range.

With manufacturing and subsidiary offices around the world and a workforce of more than 500 PI provides direct local support where it is needed. Products range from component level piezo ceramic assemblies to six axis hexapod positioning robots. PI manufactures its own piezo ceramic material including multilayer devices that incorporate its patented ceramic insulation technology. Lead free ceramic technology is now also included in the company’s product range. With the flexibility and continuity of supply offered by having control of piezo ceramic production comes security and speed of delivery for customers who rely on or are looking to move into this area of technology. PI’s piezo ultrasonic and step drive motor technologies offer unique performance including self-locking capability, high force or high speed and non-magnetic and vacuum compatibility.
