    • 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.
    • 压电致动器包括适配元件,该适配元件被配置为使压电致动器适应感应负载的控制器,特别是用于致动感应负载的转换器。 适应元件允许使用通常用于启动伺服电机的数控系统的控制器或转换器。 因此,不再需要提供用于致动压电致动器的专门设计的硬件,而是可以使用上述控制器。 此外,由于适应元件的结果,压电致动器可以集成在数控系统的总线中。 这允许通过NC总线实时通信。
