Advanced Features of the E-727 Piezo Controller
Other advanced features of the digital piezo controller include 4th-order polynomial linearization for the piezo mechanics and control electronics, an integrated data recorder, an ID chip for fast and quick exchange of the system components, as well as subordinate, programmable drift compensation. In addition, there is the option of dynamic digital linearization (DDL). DDL lowers phase shift and trajectory errors to an indiscernible level in the case of dynamic-periodic applications. This is important for scanning applications that have to identify a particular position and reach it again accurately.
Software and Additional Interfaces
Like all PI motion controllers, the E-727 comes with extensive software support, such as LabVIEW drivers and dynamic libraries for Windows and Linux. The E-727 can also be operated via TCP/IP or USB even without an EtherCAT master and commanded with PI GCS codes. Additional interfaces are SPI for fast serial transmission of position values to / from an SPI master, 4 digital I/O (each) and 4 optional high resolution analog I/O (20 bits) for external sensors, target values or external amplifiers.
