Piezo controller with digital linearization
PI improves the positioning accuracy for low-cost piezo systems
(firmenpresse) - In contrast to conventional analog piezo controllers, the E-609 single- channel piezo controller from Physik Instrumente (PI) has a digital controller which can be optimized using software and USB service interface. Additional linearization methods improve the accuracy of the piezo system in comparison to completely analog devices by a factor of 10 from around 0.2% to 0.02%.
The E-609 is equipped with analog interfaces for commanding the position. It is therefore the ideal instrument for automation tasks without host PC.
The D/A conversion of the digital controller is 16 bit, the 32 bit processor with 150 MHz clock–pulse rate allows a servo rate of 10 kHz. The amplifier provides 5 W continuous power, for the dynamic operation of conventional nanopositioning systems such as the P-736 PInano sample scanner, for example.

Unternehmensinformation / Kurzprofil:
PI has been one of the leading players in the global market for precision positioning technology for 40 years. The piezoelectric ceramics used as drive elements, which generate a finely adjustable motion, play an essential role. In cooperation with the PI Ceramic subsidiary PI produces piezo drives to meet custom requirements. This know-how allows PI to have a unique flexibility and a broad technological advance. In addition to its three German factories, PI has eight subsidiaries and a total of over 500 employees worldwide.
