Advanced drive module for integrated control system
ACS Motion Control has enhanced the drive operation of its MC4U integrated modular control system with the development of an advanced 4 axis high-voltage universal digital drive module.
Plymouth, MN— ACS Motion Control has enhanced the drive operation of its MC4U integrated modular control system with the development of an advanced 4 axis high-voltage universal digital drive module. Designated the DDM3U-4-320V, this high-density drive module is the newest component available for ACS' MC4U machine controller. The DDM3U is suited for demanding positioning applications including linear and rotary servomotors, step motors, and induction motors.
Compared to other network-based solutions that have expensive logic and control components at the drive level, the DDM3U amplifier is fully controlled by a dedicated servo processor at the controller level. This reduces cost and improves performance, allowing for more advanced control algorithms including multiple input-multiple output (MIMO) control.
"The DDM3U enables advanced drive operation in an MC4U system to provide industry-leading performance while reducing space and costs," said Jason Georges, account manager at ACS Motion Control . "No other high-density, low cost product available today achieves the level of performance seen with this multi-axis PWM drive in an MC4U integrated machine control system."
Universal control algorithms and HW construction of these drives allow users to employ many different types of motors with the same HW, including DC brush motors, DC brushless/AC Servo motors (2 or 3 phase), stepper motors (open loop or sinusoidally commutated closed loop), and AC induction motors.
The card comes in a 2- or 4-axis version, with 1A continuous / 3A peak current rating or a 3A continuous / 9A peak current rating (per axis). The DDM3U provides up to 800W of continuous power (2400W peak) per axis and operates at 24-320Vdc. Customers are guaranteed power protection to the DDM3U with over and under voltage protection, phase-to-phase and grounded short-circuit protection, over-current and over-temperature protection, and control supply missing protection.

Annual Salary Survey
After almost a decade of uncertainty, the confidence of plant floor managers is soaring. Even with a number of challenges and while implementing new technologies, there is a renewed sense of optimism among plant managers about their business and their future.
The respondents to the 2014 Plant Engineering Salary Survey come from throughout the U.S. and serve a variety of industries, but they are uniform in their optimism about manufacturing. This year’s survey found 79% consider manufacturing a secure career. That’s up from 75% in 2013 and significantly higher than the 63% figure when Plant Engineering first started asking that question a decade ago.
