The Ensemble QDe is a high-performance desktop nanopositioning piezo drive designed for use with the Ensemble line of drives and controllers. The drive connects to any Ensemble controller network, enabling coordinated motion between piezo stages and servo axes. It provides processing power over a 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 drive also features high-speed position latching capability and multi-axis position synchronized output for generation of pulses based on actual position feedback.
