PI (Physik Instrumente) LP has released a motion controller designed to handle 4, 6 or 8-axes of PIglide air bearing positioning stages and precision automation sub-systems.

The A-82x controller family integrates closed-loop digital servo control, drivers, and power supply in one 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.

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. The controllers also feature ACS ServoBoost which provides 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.

Designed to float on a cushion of air without rollers or sliding components, air bearing positioners deliver precise and vibration-free motion, with velocity stability, and zero wear of mechanical components.
