Parker: ACR Series Controller - ACR2000
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 ACR2000 is capable of Standalone or PC-bus operation. It has the ability to run up to four servo loops, with up to 4 encoders at 20MHz. It can optionally be equipped with 8 analog inputs through a 12-bit analog/digital converter and introduce these inputs into servo loops. Because of our modular design to our outputs, it is possible to have four axis of servo or four axis of stepper on the same controller. The ACR2000 controller, like the ACR8010, uses a SIMM card for analog outputs or stepper outputs and can be purchased as 2 or 4 axis. Of course, all of Acroloop’s systems run on the same software and firmware, so the standard features and benefits apply to the ACR2000 as well.
The ACR2000 is Acroloop Motion Control Systems’ answer to four axis or less affordable high performance control, when flexibility in the field, real-time speed, and ease of programming are most needed.
