  • Fully Programmable Low Pass and Notch Filters
  • 4th Order Polynomial Linearization (channel independent)
  • Coordinate Transformation for Random Sensor/Actuator Geometry
  • Automatic Zero Adjust after Power-Up

  • New: Optional High Speed DSP Link and Parallel-Port Interfaces
  • NanoCapture Software for System Optimization

 

The new E-710 Digital Piezo Controllers are based on a 32 bit DSP and integrate up to 4 independent power amplifiers for Low Voltage PZTs (6 W, -20 to 120 V) 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. 

 

Example:
Three linear sensors and 4 linear actuators suffice for precise XYqZ position control. Also, control parameters can be easily modified and optimized by software.

E-710 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 non volatile and user accessible.

Two versions of the E-710 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.
