ACS Motion Control Expands its Integrated Modular Control System Product Offering to Include 9" and 11" Modules

PLYMOUTH, MN (July 15, 2008) -- ACS Motion Control, an international manufacturer of advanced multi-axis motion controllers, machine control systems and integrated control modules, has expanded its configurable machine and motion control product offering to include 9" and 11" enclosures for two-to-four axes. Designated the MC4U 9" and MC4U 11", the cost-effective, high performance control systems integrate controllers, drives, power supplies and additional I/O and networking capabilities to provide complete control of machine automation functions -- motion, logic, power and data.

The MC4U 9" rack interfaces with four encoder feedbacks, has a single HSSI channel, a single RS232 communication port and two Ethernet ports. In addition, it provides +/-10V drive commands for two external drives.

The MC4U 11" rack interfaces with four encoder feedbacks, has two HSSI channels, a single RS232 communication port and two Ethernet ports.

"The MC4U motion control system is designed for multi-axis motion control applications where a combination of high performance, multiple support axes, flexible drive configuration, PLC motion and logic control, and convenient packaging are required," said Evan Reed, ACS Motion Control Vice President. "The new 9" and 11" racks, together with the 19" rack, enable us to offer our customers a complete, high performance control, power, and logic solution for low and high axes count applications."

The MC4U 9" and 11" racks feature ACS' SPiiPlus 3U or SPiiPlus 3U-LT motion controllers, PSM3U-48V-0.76kW or PSM3U-320V-8kW power supplies, and DDM3U-1-320V-5A/10A/20A or DDM3U-2-320V-5A/10A/20A drives.

The MC4U 9" and 11" can be ordered in two ways. A fast prototype for low volume requirements consists of standard plug-in components, mating motherboards (back panels), external network components, standard rack mount enclosure, front access panel/rack-mount and a delivery time of one to two weeks after receipt of order (ARO), thus shortening the applications time to market.

The custom configuration option provides a lower unit cost approach and integrates specific customer requirements such as standard components (controller, drives, supply), standard rack mount enclosure, specially-designed motherboard per customer needs, elimination of manual wiring, customer-preferred connectors, customer-preferred mounting and access, rack-mount with back access or front access, panel-mount with front access, and the addition of customer's plug-in cards with a delivery time of up to three months ARO.

Designed for panel or rack mounting, all connections are accessible from the front, making the MC4U configurable any number of ways to meet exact customer specifications. The MC4U also features logic control with OpenPLC standard IEC 61131-3 PLC control and communications for data management with two Ethernet ports.

The MC4U system integrates robust and reliable power supplies designed specifically for the MC4U system; high-performance PWM drive blocks featuring digital current loop control for smooth constant velocity; linear drives that eliminate jitter; and three-phase motor filters that increase motor functionality by reducing the common mode and the differential mode noise; to provide a low-noise, low-position jitter and low-cost motion control solution.

Developed for OEM production, test or inspection equipment, semiconductor, electronic assembly, general automation, medical and flat panel display applications, the MC4U is the first configurable solution built using standard components, resulting in shorter development cycles, reduced risk and lower costs.

Optimized for motion control applications, ACS' powerful software tools provide easy setup, tuning and programming and application simulation. The software enables the implementation of highly complex motion-time-event sequences with accurate positioning and timing. The free motion simulator can be downloaded at .
