Abstract
A piezo actuator includes an adaptation element, which is configured to adapt the piezo actuator to a controller for inductive loads, particularly to a converter for actuating inductive loads. The adaptation element allows use of controllers or converters of numerical control systems, which normally are used for actuating servo motors. Therefore it is no longer necessary to provide specially designed hardware for the actuation of piezo actuators, but instead the above-mentioned controllers can be used. Furthermore, as a result of the adaptation element, the piezo actuators can be integrated in the bus of the numerical control system. This allows communication in real time via the NC bus.
