NV 200/D Controller – Description

The new NV 200/D controller is built to deliver powerful high-resolution signals offering a wide variety of control options including ethernet and USB – C. With 400 mA of peak current, the system can provide high frequencies and fast response times, while still maintaining 16 bit resolution and less than 0.7 mV of noise.

The NV 200/D comes with an integrated closed loop control, as well as Iterative Learning Control for closed loop precision at open loop speeds.

PiSoWorks – NV 200/D Net Controller Software

For precise control of the NV 200/D controller, the included PiSoWorks software gives the user complete control over both the actuator and controller for a complete solution.

PiSoWorks software is available immediately for download and set-up is easy. Once the NV 200/D NET amplifier is connected to your computer and your actuator, the system is ready for use.

When the software is first downloaded, set-up and connected via ethernet, it will automatically identify and display the connected amplifier and actuator.

Device Select Screen

The PiSoWorks software features a comprehensive graphical user interface that allows for control of your actuator in two optional modes – Easy Mode and Advanced.

Easy Mode examples:

  • Switch between open loop and closed loop control.
  • Set piezo actuator to a specified location.
  • View graphically the realized motion of the actuator after the actuator has jumped to the specified location.

Advanced Mode examples:

  • Manually adjust PID values for closed loop control.
  • Control piezo actuator dynamically by manually setting the internal signal generator.
  • Upload custom wave forms to control the piezo according to individual needs.
  • Determine resonance spectrum of the piezo (with added load) at the push of a button.
  • View graphically the realized motion of the actuator after the piezo responds to the desired wave form.

Waveform Movement

One special Advanced Mode function is ILC (Iterative Learning Control). ILC functionality uses a proprietary algorithm to generate higher closed-loop speeds compared to regular PID control. The ILC learns the actuator’s unique behavior and then compensates for unwanted motion that would normally slow a typical closed-loop system. ILC is especially useful for users who need to achieve precise repetitive actuator motion.

ILC Advanced Mode – Decreasing of the waveform deviation

Using PiSoWorks software, simplifies system set-up, and gives the user precise comprehensive control of the NV 200/D and the connected actuator. The software and user manual can be downloaded here.
