Air Bearing Motion Controller improves the performance of stages equipped with direct drive servo motors and high-resolution encoders.

Press Release Summary:

A-82x Family Air Bearing Motion Controllers are combined with closed-loop digital servo control, drivers and power supply in a rack mount design. Units are suitable for metrology, photonics alignment, semiconductor, wafer inspection and laser marketing operations. Controllers deliver an output ranging from 1100 W to 2000 W depending on the number of axes and are supported by incremental and absolute encoders that are based on BiSS-C protocol. Air Bearing Motion Controllers also feature ACS ServoBoost™ for consistent and stable servo performance that is insensitive to noise or changes in the system.


Original Press Release:

4 / 6 / 8 Axes Advanced Motion Controller for Linear & Rotary Air Bearing Motion Stages

This new air bearing controller from PI optimizes the performance of stages equipped with direct drive servo motors and high-resolution encoders.

Nano precision motion industry leader PI (Physik Instrumente) LP has released a new high-performance motion controller designed to handle 4, 6 or 8-axes of PIglide air bearing positioning stages and precision automation sub-systems. Air bearings provide many advantages compared to mechanical bearings, such as no-particle generation, frictionless, vibration-free motion, highly constant velocity control, nanometer-precision repeatability, and optimal geometric performance.

Based on ACS Motion Control Hardware - High Output Power up to 3.9KW The A-82x controller family integrates closed-loop digital servo control, drivers, and power supply in one convenient rack mount design. Depending on the number of axes, total output power of 1100W to 2000W with peak power to 3900W is provided.

A-82x controllers can be operated in stand-alone mode running on stored programs in the integrated flash memory in addition to control via an external computer.

High resolution incremental encoders with sine/cosine output and absolute encoders based on BiSS-C protocol are supported. The multi-axis controllers are based on ACS hardware, a global motion control leader which became part of the PI Ggroup in 2017. The new controllers also feature ACS ServoBoost™ which provides better, more consistent and stable servo performance that is insensitive to noise or changes in the system. The PI Group also offers standard and custom motion systems and controls for precision automation applications.

Why Use Air Bearings?

Designed to float on a cushion of air without rollers or sliding components, air bearing positioners deliver extremely precise and vibration-free motion, with excellent velocity stability, and zero wear of mechanical components, which are ideal for high-end industrial inspection and manufacturing operations.

Applications

High precision operations, such as metrology, photonics alignment, semiconductor, wafer inspection, laser marketing, flat panel display, precision scanning applications, and cleanroom applications 200+ Man Years of In-House Air Bearing Design Experience
