E-754 Digital Piezo Controller High-Speed, Single-Axis Controller
• Next generation digital controller provides higher flexibility, accuracy and speed
• Auto-loading of calibration data from stage ID chip for interchangeability of controller and mechanics
• Analog inputs and outputs
• Digital I/O lines for task triggering
• Extensive software package
• For nanopositioning systems with capacitive sensors
The E-754 digital controller from PI is the result of more than 30 years of experience with piezo positioning systems. It provides ideal control for the highest demands on positioning accuracy and dynamic performance of high-class precision nanopositioning systems. The E-754 replaces the E-753 controller and exceeds its performance by a factor of three.
Digital linearization for the highest accuracy
Linearization algorithms based on higher-order polynomials reduce the linearity error to less than 0.01 % with capacitive sensors. That is typically 10 times better than conventional controllers.
During fast periodic motion, such as that typical for scanning applications, it is possible to increase the tracking accuracy by up to a factor of three using Dynamic Digital Linearization (DDL, E-710.SCN).
High velocity and bandwidth for dynamic applications
The controller is perfectly suited for high-dynamics operation thanks to its high-resolution D/A converter and high-performance voltage amplifier. The high-speed processor with a sensor sampling rate of 50 kHz ensures settling times in the millisecond range and below.
Flexible customization for a variety of applications
The ID chip contains the calibration and servo-control parameters of the mechanics for PI nanopositioning systems that are equipped with an ID chip and were calibrated with digital electronics. The controller reads the data "intelligently" to adapt itself automatically to the mechanics connected and therefore renewed calibration is unnecessary after changing system components.
The integrated wave generator can save and output periodic motion profiles. Preconfigured sine and triangle wave profiles are provided to support the user when defining the curve, but any user-defined waveforms are possible.
Easy system connection
All parameters can be set and checked via software. Easy start-up and system configuration takes place via the PIMikroMove utility program included in the scope of delivery. Connection to the customer's software is possible via LabView drivers and shared libraries. System programming is identical for all PI controllers – combined control of a variety of different controllers is therefore possible without any problems.
