Digital, panel-mount piezo drives for coordinated motion
Aerotech's Ndrive QLe is a family of digital, panel-mount, nanopositioning piezo drives designed to enable coordinated motion between piezo stages and servo axes.
Aerotech’s Ndrive QLe nanopositioning piezo drives are designed to enable coordinated motion between piezo stages and servo axes. The QLe drives feature a dual-core 456 MHz, double-precision, floating-point DSP and provide processing power in applications including point-to-point motion, linear and circular interpolation, multi-axis error correction, and autofocusing. High-speed position latching and single-axis or multi-axis position synchronized output (PSO) generate pulses based on actual position feedback for applications ranging from laser firing to data acquisition system triggering. The QLe is also designed to enable sub-nanometer positioning resolution at high bandwidths and capacitive sensor feedback circuitry provides low noise performance over the full travel range. The Ndrive QLe features four optically-isolated digital inputs, two high-speed digital inputs, and four optically-isolated digital outputs as well as two analog inputs and two analog outputs. The QLe offers an 18-bit analog input that can be configured to accept an external feedback sensor or position command. This analog input also allows the high-voltage power amplifier to be controlled directly by an external low-level analog input. Also, the QLe has one 20-bit analog output that can be programmatically configured for position or voltage monitoring at very high resolutions.
