The new actuator series PAHS from piezosystem jena achieves higher motion at only 20% more length than conventional actuators. With more than 4 times higher travel than normal piezo actuators, they are a perfect solution when space is limited but still high resolution requirements exist. They offer a similar repeatability as a standard system.

PAHS actuators operate with the same voltage band of 150V and can therefore easily be integrated into existing systems by using the same controllers and amplifiers from piezosystem jena.

Like the PAHL Series, these actuators have high blocking forces and can move large masses. They possess an integrated mechanical preload and their high resonant frequency guarantees short settling times. Therfore, PAHS actuators are an easy plug and play solution when space is critical.

Due to overshooting and hysteresis, the output curve from a piezoelectric actuator can differ from its input signal. The iterative learning control (ILC) method, as developed by piezosystem jena, determines the required setting curve by performing iterations and adjustments on measured curves. Besides the improvement of accuracy, ILC offers advantages such as the production of dynamic movement even above the system’s resonant frequency, and flexibility regarding changing conditions of, for example, load and temperature. In addition, there is no longer a need for users to have their systems recalibrated.

piezosystem jena has developed the next generation of smart controllers with a new software interface: The NV200/D Net - a digital piezo controller with a max output current of 400mA (peak current). With its 16-bit resolution and a noise level of 0.3mV, the NV 200/D Net guarantees fast response times and high positioning accuracy. The integrated new software PiSoWorks gives the user complete control over both the actuator and its motion profile. The user only needs one cable. The software allows for control of the actuator’s exact position, speed and open and closed loop control. The software includes a function generator for open and closed loop control. Thereby positions are stored in a data recorder.
It has two different modes, easy and advanced mode. Easy mode allows for quick function test. In the advanced mode there are several additional controlling options like PID controls, set-smooth and iterative learning control.
