Aerotech’s Ensemble QLe controls up to ten axes of piezo and/or servomotor stages.

15-Oct-Aerotech-Piezo-Drive-360Aerotech unveiled its Ensemble QLe, a panel-mount nanopositioning piezo drive designed for the company’s Ensemble family of drives and controllers. Featuring a dual-core 456 MHz, double-precision, floating-point DSP, the drive provides high-speed interrupts, data logging, high-speed position latching and multi-axis position synchronized output (PSO). Using high-resolution A/D and D/A converters, the QLe enables sub-nanometer positioning resolution at high bandwidths, with linearity is better than 0.01% over the full travel range in closed-loop mode. In addition to two high-speed digital inputs and four optically-isolated digital outputs, the drive is equipped with analog inputs and outputs including an 18-bit analog input and one 20-bit analog output. Ensemble software uses advanced PID servo loops with feedforward and multiple integrators coupled with eight programmable filters.
