Multi-Channel Digital Piezo Controller offers broad connectivity.

Press Release Summary:



Integrating with existing piezo-based nanpositioning systems and piezo actuators, E-727 features 20-bit DACs and ADCs, 4 PAs, PID control, and 2 programmable notch filters. Closed-loop nanopositioning systems are supported with capacitive feedback sensors, piezoresistive sensors, and strain gauges. Linearization fosters positioning accuracy, and DDL eliminates non-linearities at high frequencies. Data recorder, ID chip compatibility, and programmable drift compensation are also standard.



Original Press Release:



PI's New High Performance Multi-Channel Digital Piezo Controller is Cost-Effective Too



Auburn, MA – PI (Physik Instrumente) L.P., an industry leader in precision motion components, systems, and solutions, has released a new, high-performance 3 and 4-channel digital piezo controller that integrates with a wide range of existing piezo-based nanpositioning systems and piezo actuators.



Lower Price, Higher Performance

The new E-727 replaces the E-725 controller and combines higher performance with a lower price. Compared to its predecessor, it provides 3 additional high-resolution analog interfaces, a faster servo, as well as a broader choice of traditional, high-speed, and real time digital interfaces, such as SPI, Ethernet, USB and RS-232



Ultra-Low Noise Controller

20-bit DAC & ADC converters keep the closed-loop E-727  controller operating with high resolution and ultra-low noise, along with 4 integrated power amplifiers for multilayer piezo drives with operating voltage of -30 to +130V. Closed-loop nanopositioning systems are supported with capacitive feedback sensors, piezoresistive sensors, and traditional strain gauges. In addition to PID control, 2 additional user programmable notch filters are implemented for suppression of mechanical system resonances. Linearization based on 4th order polynomials provides higher positioning accuracy. The Dynamic Digital Linearization (DDL) feature eliminates non-linearities at high operating frequencies.



Data Recorder, Auto-Calibration ID Chip, Quick Start UP, Comprehensive Software Package

The cost-effective E-727 has a data recorder for high speed tracing, ID chip compatibility for quick start-up, and exchange of system components without recalibration, and the additional feature of programmable drift compensation. The controller comes with extensive software support for LabVIEW and shared libraries for Windows and Linux. Multiple digital interfaces for ease of control: Ethernet, USB, RS-232, SPI. Four (4) digital I/O channels as well as four (4) high-resolution analog inputs and outputs each are also available for use with external sensors, target values or external amplifiers.
