Description
EBD-060 digital controllers provide closed-loop operation of piezo-systems. Such systems consist of low-voltage piezo-actuators combined with position sensors. EBD-060 control via full-bridge strain-gauge sensors. The nFControl Basic Software offers the ability to easily change control parameters via a Windows-based GUI. The controllers´ versatile enclosures allow for either simple integration into OEM equipment or table-top usage.

How do Controllers work?
Controllers for piezo-systems interact between actuators, sensors and users:
Digital controllers allow for easily adapting and optimizing control parameters (PID, notch-filters) and exchangability of connected mechanics (ID-Chip). Such controllers are typically equipped with analog and digital interfaces – USB, Ethernet and RS232. Graphical user interfaces (GUI) provide examination features like oscilloscope (view step-responses, rest-noise, etc.) and FFT (see Bode-Plots of amplitudes and phases over frequency).
Example, open loop:
