Bringing together what belongs together


Mixed Operation of up to 40 Axes with One Controller

During operation, it is often necessary for several drive axes to work together. On top of that, further motion controllers are necessary, which have to be started up individually and must be connected to the higher-level control. The time and financial resources required for this should not be underestimated.

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.
