The new Yaskawa A1000 is a full featured drive, providing outstanding quality, performance, flexibility, and environmental friendliness through 1000 hp. This new family of drives offers many benefits, including a design life twice as long as previous generations. For ease of setup, the A1000 supports DriveWizard software and a portable USB copy unit. In addition, Application Presets are available for fans, pumps, compressors, and conveyors.

When it comes to periodic maintenance, the A1000 provides alarms when it’s time to change replaceable components. Additionally, mean time to replace is optimized with a removable I/O module that stores a copy of drive configuration.

For demanding applications, the A1000 generates 200% torque at zero speed, with or without feedback. Continuous auto-tuning provides smooth operation, even at very low speeds. Fast acting algorithms keep applications running during periods of high demand. The A1000 also controls permanent magnet motors for impressive gains in efficiency and performance, the company said.

Yaskawa DriveWorks EZ reduces total system cost and adds flexibility function block capability with a variety of control modules for specific applications. Production time and efficiency are maximized with an auxiliary control power input that maintains network communication while main power is removed. Embedded functional safety minimizes downtime for applications requiring occasional intervention.

For sustainability reasons, all materials used comply with the European directive for Restriction of Hazardous Substances. Also with built-in reactors, power system harmonic distortion is greatly reduced.

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.
