Parker: ACR Series Controller - ACR1200
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 ACR1200 is Compumotor’s OEM two-axes standalone controller. The ACR1200 is a standalone controller card only and offers no PC port as an option. It comes with two serial ports–RS232 and RS422–and has the ability to run two servo loops with up to three encoders at 20 MHz. It can also be equipped with eight analog inputs through a 12- or 16-bit analog/digital converter and introduce these inputs into the servo loop. Because of the modular design of our outputs, it is possible to control 2 servo or 2 stepper axes on the same controller. This level of control has previously not been available at this price. 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.
The ACR1200 is Compumotor’s answer to affordable, highperformance, standalone control when low cost, real-time speed and ease of programming are most needed.
