Yaskawa America offers the Z1000 family of variable-speed drives.
The Z1000 family of variable-speed drives from Yaskawa America Inc. is designed for building automation applications such as fans, pumps, and cooling towers through 500 hp. Its features begin with an easy-to-read LCD operator with hand-off-auto functions. An internal real-time clock with time/date stamping and timer controls allows for speed variations without the need for external controls. A built-in 5% line impedance reduces input harmonic distortion, while a 5 kHz carrier frequency with dynamic noise control provides quiet motor operation. An on-board EMI/RFI filter compliant with IEC 61800-3 minimizes interference of surrounding equipment. All Z1000 drives also feature embedded BACnet communications (BTL certified), along with Modbus/Memobus. Applications macros are available to facilitate quick and easy setup.
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.
