Piezo drive networkable for integration with piezos and servos
Aerotech's Ensemble QDe is a high-performance desktop nanopositioning piezo drive designed for seamless use with the Ensemble family of drives and controllers. The QDe connects to any Ensemble controller network enabling coordinated motion between piezo stages and servo axes at much higher rates than other controller or drive products. This power and versatility make the Ensemble QDe suitable for single or multi-axis applications ranging from fundamental scientific research to advanced OEM machine systems.
The QDe provides extreme 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 features 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 the latest technology and high-resolution A/D and D/A converters, the QDe enables sub-nanometre positioning resolution at high bandwidths. The QDe capacitive sensor feedback circuitry results in very low noise levels over the full travel range. An Aerotech developed linearisation method achieves linearity better than 0.01 per cent over the full travel range in closed-loop mode.
The Ensemble QDe uses PID servo loops with advanced feedforward and multiple integrators coupled with eight programmable filters to supply the user with all necessary tools needed to optimise motion performance. The Aerotech Dynamic Controls Toolbox and Motion Designer packages make available a host of advanced, yet easy-to-use, tools such as 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.
Product features:
- Networkable with any Ensemble drive to control up to 10 axes of piezo and/or servomotor stages
- Multi-axis Position Synchronized Output (PSO) for real-time triggering of events
- High-precision 20-bit sensor resolution for capacitive sensor feedback
- Advanced features such as learning control, harmonic cancellation, and command shaping improve tracking error and throughput
