NPC-D-6000 Series Multi-channel Closed Loop Controllers


The QGNPC-D-6000 Series are multi-channel nanopositioning controllers. Designed specifically to control Queensgate Stage Mechanisms and Actuators with piccometer positioning resolutions.

The QGNPC-D-6000 Series Closed Loop Controllers are the latest generation of NanoPositioning systems from Queensgate. Designed specifically to control Queensgate’s Nanometer Precision Mechanisms. Using state of the art digital signal processing technology the QGNPC-D-6000 series combine piezo drive amplifiers, capacitance position sensing circuitry and servo control capability.

When a controller is used in a synchrotron, the infrequent access to their stages/actuators can maintain systems by exchanging controllers with minimal effect on calibration. This keeps beamline down time to minimum having significant financial savings to them.

In our OEM systems it allows integrators of our product to easily support systems by exchanging electronics as required with minimal change in performance. There is no need to return stages that are healthy to be recalibrated with their controller.

There is no need to return stages that are healthy to be recalibrated with their controller. With any demonstrations it allows multiple stages to be calibrated with the same controller.

General Specifications
• Closed loop controller with open loop operating mode. Capacitance sensor measurement circuitry for precision closed loop operation.
• Digital signal processing with 24 bit data resolution. Fast 20µs control loop update.
• 4th order linearization algorithm for high positional accuracy.
• Supports Plug and Play NanoMechanisms. The calibration and dynamic settings are held in the stage EEPROM allowing controllers to be interchanged with minimal impact on performance.
• Two notch filters for tuning to meet specific application requirements, reducing noise and preventing stage ringing.
• The low noise design allows stage position noise as low as a few tens of picometres. Delivering a stable system with repeatability of movement, precision and accuracy for precise imaging and focusing.
• Dynamic high-power output NanoMechanism drive with 20 bit resolution.
• Optimized acceleration/deceleration contribute to high speed positioning applications by reducing overshoot and settle time.
• Soft-start/stop technology protects loads and increases piezo life.
