PI (Physik Instrumente) L.P. PIglide Motion Controller for 4, 6 or 8 Axes A-82x

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: Sub nanometer 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.
