Parker: ACR Series Controller - ACR1500

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 ACR1500 is Compumotor’s OEM 4-axes PC bus-based controller. The ACR1500 is a PC bus-based card only and offers no serial or LPT ports as an option. It has the ability to run up to four servo loops with up to four encoders at 8 MHz (post-quadrature). The ACR1500 can also be equipped with eight analog inputs through a 12- or 16-bit analog-to-digital converter and introduce these inputs into the servo loop. Because of the modular output design of the ACR family, it is possible to have two axes of servo with two axes of steppers on the same controller or all axes of one type. Unlike other members of the Compumotor Acroloop controller line, the ACR1500 utilizes a 16-bit bus, which reduces cost dramatically. With this feature, the ACR1500 provides a high level of control at roughly half the cost! 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.
