Concept:
The NV200/D NET is a digital piezo controller with a serial and an ethernet interface for local and remote control and servicing of piezo actuators. The user can drive quasi static or dynamic step positioning applications through the network access, allowing for more flexibility and use in critical environments. For high dynamical applications, a real time SPI interface is implemented. The amplifier can drive piezoelements with up to 400 mA. With a 16 bit resolution, the NV200/D NET guarantees high positioning accuracy and low noise. The NV200/D NET can automatically recognize actuators and adjust control parameters from stored information in the EEPROM connector. The NV200/D NET can be used with actuators equipped with either strain gauge or capacitive sensors, as well as with actuators without measurement system. The NV200/D NET also supports actuators based on piezosystem jena’s own NanoX® bi-directional actuating technology.

Features:
The NV200/D NET has an automatic sensor calibration (ASI / ASC) function. All values of the actuating system, like serial number of the actuator, actuator name, control parameters and filter settings, are stored in the actuator plug. This allows an easy exchange of actuators or controllers. A digital PID controller is integrated in the device. For repetitive motion patterns, an iterative learning control (ILC) algorithm can be used to achieve highest tracking precision. In this way, the NV200/D NET can achieve closed loop precision at open loop speeds. Due to its trigger input and output functions additional units of the NV200/D NET can be synchronized to control multiple axes.
