The E-761 PCI bus piezo nanopositioning digital motion controller announced by PI (Physik Instrumente) LP controls three logical axes of closed-loop piezoelectric nanopositioning systems with capacitive position feedback. Its PCI interface provides high-throughput and precise motion synchronization with frame grabbers and other peripheral devices. The system also has a high-bandwidth analog position control input for external triggering applications. The four onboard piezo drivers require no external amplifiers. Features include a 32-bit digital signal processor, 24-bit digital-to-analog converters for subnanometer position resolution, polynomial linearization and coordinate transformation.
