E-712 数字式压电控制器


PI E-712.M1

Digital linearization for the highest accuracy

Linearization algorithms based on higher-order polynomials reduce the linearity error to less than 0.01 %. That is typically 10 times better than conventional controllers.

Fast periodic motion and data recording

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). 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. Flexible configuration of the data recorder allows recording of the corresponding data.

Flexible analog inputs and real-time PIO

Each of the four optionally available analog inputs can be configured in two ways. As control input, the voltage applied is linked to one of the axes, e.g., for target values. Configuration as external sensor input allows reading of additional sensor signals, e.g., for autofocusing. Alternatively, the system can be equipped with a fast 32-bit PIO (parallel I/O) for commanding. The PIO supports a restricted command set with 100,000 read and write commands per second required for motion.

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.
