Parker: ACR Series Controller - ACR8020

The ACR Family of Controls

Since the acquisition of Acroloop Motion Control Systems in 2002, the ACR family has been the highest performance motion controls in the Parker offering. Each of the five versions of the product is based on a 32-bit floating-point DSP producing unparalleled performance in the area of advanced multi-axis trajectory generation. Because the products are built upon a scalable platform, the same software set works on each of the controllers, providing easy upgrades and transfer of established application code between machines and applications. The hardware is also extremely flexible, allowing the design engineer to easily create the perfect controller configuration for his machine. The power of the ACR hardware is matched by an equally impressive array of software features allowing the design engineer the ability to solve any motion application.
The ACR8020 is Compumotor’s premier controller for PCI bus operation. It has the ability to run eight servo loops (16 with expansion board), DAC or Stepper outputs and 10 encoders (20 with expansion board) at 20 MHz counting rate. It can also be equipped with up to 8 analog (12- or 16-bit resolution) inputs. Multi-axis coordinated motion can be performed in multiple groups of axes. Because of the ACR8020’s modular design, a combination of both servo and stepper axes can be applied on the same controller. All of Compumotor’s Acroloop products utilize the same system software and programming language; this assures users complete flexibility in upgrading their hardware while maintaining their investment in program development.
