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
- ServoBoostTM upgrade. Provides better, more consistent servo performance that is insensitive to noise or changes in the system.
- ServoBoostTM PLUS upgrade. Provides higher position stability and velocity constancy.
- Additional control axes for external drives via EtherCAT
- Alternative customized packaging for OEM setups
