Potentiometer control increases inverter flexibility
The ability to use potentiometer control is useful in hands-on applications where speed must be ramped up/down such as material handling or food/beverage processes.
A potentiometer option is now available for SMVector NEMA 4Xinverter models. The potentiometer option is built into the terminal cover,providing direct front panel access. The potentiometer knob takes the place ofthe up/down buttons on the drive keypad, giving the operator manual speedcontrol over a 0-10 V analog output. The ability to use potentiometer controlis useful in hands-on applications where speed must be ramped up/down such asconveyer or food/beverage process applications.
The SMVector inverter drive still provides features required
by demanding applications including four modes of operation: V/Hz, enhanced
V/Hz, vector speed and torque; plus high starting torque, auto-tuning, advanced
low-speed control and dynamic speed regulation. The potentiometer option
increases the inverter's flexibility and applicability to industrial applications.
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.
