The E-710 high performance Digital Closed-Loop Piezo Controllers are based on a 32 bit DSP and integrate up to 4 independent piezo drivers and high voltage piezo amplifiers for piezo nanopositioning stages and conditioning electronics for up to 4 capacitive position sensors. In contrast to analog multi-axis controllers, E-710 controllers have a distinct advantage: sensor and output channels of two or more axes can be combined by an internal coordinate transformation. 


Three linear sensors and 4 linear actuators suffice for precise XY-theta-Z position control. Also, control parameters can be easily modified and optimized by software.

E-710 closed loop piezo controllers are equipped with fast RS-232 and IEEE 488 interfaces. All positioning commands are in standard units such as micrometers, microradians, etc., for easy programming. In addition, all control settings are nonvolatile and user accessible.

Two versions of the E-710 digital piezo controller are available: E-710.4CL is the 4 channel version with individual sensor and piezo drive voltage LEMO connectors for each channel. Version E-710.3CD is equipped with one D-Sub connector for three sensor channels and four Piezo drive voltage channels, specially designed for XYqZ positioners such as P-517.RCD.
