Controller is precise with piezo positioning

Digital piezo stage controller answers the most demanding accuracy and dynamic-performance demands of multi-axis piezo nanopositioning systems.

PI has designed its new E-712 digital piezo stage controller for the most demanding accuracy and dynamic-performance requirements of multi-axis piezo nanopositioning systems.

Its highly modular design allows flexible configuration, easy upgradeability and adaptation to changing requirements in any scanning or positioning application.

Thanks to its high-performance processor and real-time operating system the controller can precisely control the trajectory of up to six axes even during high-velocity motion on a millisecond timescale.

Proprietary linearisation algorithms deal with the nonlinear nature of PZT actuator material and reduce motion errors to 0.001% of the travel range.

The high position sensor sampling rate of 50kHz, provides plenty of margin even for ultra-fast piezo stages with submillisecond response times.

20bit D/A convertors and ultra-low-noise voltage amplifiers round out this cutting edge system.

With USB, Ethernet, RS232 and optional high-bandwidth analogue interfaces the controller can adapt to any environment.

Ethernet allows remote control and complete system setup, configuration and parameter readout through the Internet, a decisive advantage for OEMs.

All parameters can be checked and reset via software.

User-interface software, LabView drivers and DLLs are provides and PI's general command set (GCS) lets users swap the controller for any other PI unit in the future without rewriting their code.
