Suitable Motion Controller for all Ultrasonic Piezo Motors and Stages


From Precision Positioning to Handling

Piezo-based ultrasonic drives ensure high dynamics and compact dimensions in positioning systems. An integral part of the philosophy behind the PILine® drives from PI (Physik Instrumente) is the flexibility to respond to user requirements. In this context, the range of motion controllers has now been expanded. This makes a wide spectrum of single and two-channel versions available that can be used according to the application from precision positioning (C-867) up to the handling (C-877).

Featured Facts

PI Expands its Technological Spectrum


Air bearings are essential for nanometer precision motion with extremely high velocity stability over long travel ranges. In contrast to mechanical guides, the air bearing enables the moving platform to glide over a layer of air with almost no friction at all. This means that no hysteresis or backlash occurs and when combined with linear motors, it is possible to reach very high velocities.

Above all, air bearings ensure excellent guiding accuracy, which means straightness and flatness of motion well below one micrometer. PI has implemented on dual motor axis of PIglide HS Planar XY stage an active yaw control algorithm. Y-Axis and Yaw Axis have separate control loops for linear and rotational motion control.
