Motion control: Powerful, compact stepper drive

The AMCI 4.0 Amp microstepping drive can drive 4-, 6-, or 8-lead step motors in NEMA sizes 23-42.


AMCI’s SD17040C microstepping drive

AMCI introduces a space saving, powerful, 170V bus, 4.0 Amp microstepping drive. The SD17040C can drive 4-, 6-, or 8-lead step motors in NEMA sizes 23-42. It is designed to withstand demanding applications, with board-level components rated to 105oC (221oF), and includes as standard switch selectable microstep resolutions, automatic idle current reduction, anti-resonance, short circuit protection, and overtemperature circuitry.
Because the SD17040C is an AC line-powered drive, no additional power supply is required, reducing overall costs. With panel or side mounting options, it can be installed into tight spaces without supplemental fans or cooling aids. The use of DSP (Digital Signal Processor) technology in combination with high quality transistors has enabled AMCI to customize the drive's performance for most applications, while also reducing space within the unit.
Additional features include: 16 switch selectable microstep resolutions, up to 50,800 steps/rev; selectable self test feature; interlock safety feature and short circuit protection; programmable automatic idle current reduction; and anti-resonance. It is also 100% compatible with all of Advanced Micro Controls Inc. 's stepper controllers and motors.

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.
