Motion controller for linear and rotary air bearing stages from PI

April 6, 2017 By Miles Budimir Leave a Comment

PI (Physik Instrumente) has released a new high-performance motion controller designed to handle 1, 2 or 4-axes of PIglide air bearing positioning stages. Air bearings provide advantages over mechanical bearings when frictionless vibration-free motion is required, highly constant velocity control is crucial, and when angular repeatability and geometric performance must be optimal.

Equipped with ultra-low noise PWM drives, the A-81x controller integrates closed-loop servo control, motor drives, and power supplies in a compact 19-in. rack mount design. The controllers support high-resolution incremental encoders with sine/cosine output and absolute encoders based on BiSS-C protocol. The multi-axis controllers are based on ACS hardware, a company recently acquired by PI. The PI Group also offers custom motion systems and controls for precision automation applications.

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. Air bearing stages are ideally suited for high precision applications, such as metrology, photonics alignment, semiconductor, wafer inspection, laser marketing, flat panel display, precision scanning applications, and cleanroom applications.
