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.

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.

Extensive functions, software support

Powerful macro command language. Nonvolatile macro storage, e.g., for stand-alone operation with autostart macro. Data recorder. P-I controller, parameter changing during operation. Extensive software support, e.g., for LabVIEW, C, C++, MATLAB, python. PIMikroMove user software.
