The modular design of Physik Instrumente’s new E-712 digital piezo stage controller for multi-axis piezo nanopositioning systems, allows flexible configuration, easy upgradeability and adaptability to changing requirements in any scanning or positioning application. Features and advantages include:
Digital controller of the latest generation: up to 50 kHz sensor update rate; highly stable 20-bit D/A converters, 600 MHz processor
Ethernet interface for remote control via the Internet
Real-time operating system for better multi-axis trajectory control
Digital linearisation algorithms based on higher-order polynomials improve the positioning accuracy to 99.999% of the travel range
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 50 kHz, provides plenty of margin even for ultra-fast piezo stages with sub-millisecond response times. 20 Bit DA-converters and ultra-low noise voltage amplifiers round out this cutting edge system.
