Overview

The A-81x motion controller series from PI offers a fully integrated electronics solution with controller, drives, and power supplies in a compact 19-inch rack unit. The A-81x 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.

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-81x 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 A-81x motion controller features the state-of-the-art ACS SPiiPlusEC motion controller and EtherCAT master.

Options and Upgrades

  • Absolute encoders or incremental encoders (can be combined individually 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 a higher position stability and velocity constancy.
  • Additional control axes for external drives via EtherCAT®
  • Alternative customized packaging for OEM setups
