Overview

The A-82x motion controller series from PI offers a fully integrated electronics solution with controller, drives, and power supplies in a compact 4-U-high 19-inch rack unit. The A-82x controllers are designed and optimized for PIglide air bearing stages that are equipped with direct drive linear and rotation servo motors, and high-resolution encoders. The A-82x motion controller features the state-of-the-art ACS SPiiPlusEC motion controller and EtherCAT master.

Standard options include inputs for incremental sine/cosine and absolute encoders that use the BiSS-C data protocol. Support for sine/cosine encoders has an integrated interpolation factor of 16384x. All controllers feature integrated flash memory for stored motion programs and parameters.

The A-82x controllers can be operated in stand-alone mode running stored programs, or controlled via an external PC. A PC is required for programming and startup. All software is supplied with the controller.

If the controller is purchased together with a PIglide air bearing stage or positioning system, PI will perform the servo tuning, startup of the controller, and error calibration, and supply a complete ready-to-use positioning system.

The NanoPWM technology from ACS is integrated into the A-824.2Nx00 models. They offer the best possible solution for demanding positioning applications: Subnanometer position holding, tracking errors limited to a few nanometers, optimal velocity constancy. NanoPWM are a genuine alternative to linear drives: Comparable performance at a lower price with less space required for the overall system.

Options and Upgrades

Absolute encoders or incremental encoders (can be combined according to customer specifications for all axes of the controller)
G-Code programming
Input shaping
ServoBoost^TM upgrade. Provides better, more consistent servo performance that is insensitive to noise or changes in the system.
ServoBoost^TM PLUS upgrade. Provides higher position stability and velocity constancy.
Additional control axes for external drives via EtherCAT
Alternative customized packaging for OEM setups
