PITTSBURGH, 20 Aug. 2015. Aerotech Inc. in Pittsburgh is introducing the Ensemble QDe high-performance desktop nanopositioning piezo drive for single or multi-axis motion control applications ranging from fundamental scientific research to advanced OEM machine systems.

The QDe, which is for use with the Ensemble family of drives and controllers, connects to any Ensemble controller network enabling coordinated motion between piezo stages and servo axes.

The QDe provides processing power over a wide variety of applications including point-to-point motion, linear and circular interpolation, multi-axis error correction, and autofocusing.

High-speed interrupts and data logging capabilities provide a real-time link to external systems. The QDe also has high-speed position latching capability and multi-axis position synchronized output (PSO) for generation of pulses based on actual position feedback in applications ranging from laser firing to acquisition system triggering.

Using technology and high-resolution A/D and D/A converters, the QDe enables sub-nanometer positioning resolution at high bandwidths. The QDe capacitive sensor feedback circuitry results in low noise levels over the travel range. An Aerotech developed linearization method achieves linearity better than 0.01 percent over the travel range in closed-loop mode.

The Ensemble QDe uses PID servo loops with advanced feedforward and several integrators coupled with eight programmable filters to supply the user with all necessary tools needed to optimize motion performance.

The Aerotech Dynamic Controls Toolbox and Motion Designer packages have tools like Learning Control, Harmonic Cancellation, Command Shaping, and Cross-Axis Feedforward to improve tracking errors and provide faster step-and-settle times.

Pre-coded LabVIEW VIs, AeroBasic programming functionality, MATLAB library, .NET tools for C#, VB.NET, and C++/CLI or C make the Ensemble even easier to use. For more information contact Aerotech online at www.aerotech.com.
