Suitable for all Piezo Actuator Nanopositioning Systems Nov 25, 2015

The All-Rounder Among the Digital Controllers

In this case, digital controllers are usually the best choice, especially since high-performance devices are now available on the market that do not cost any more than an analog controller. They are just as fast, but at the same time, they offer advanced servo algorithms. An example of this is the new E-727 three-channel digital controller from PI (Physik Instrumente). The high-resolution AD/DA converter and piezo amplifier can be considered as a genuine “People’s Controller” for all piezo actuator nanopositioning systems, irrespective of whether these work with capacitive, piezo-resistive or strain sensors.
