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

Before the calendar turned, 2016 already had the makings of a pivotal year for manufacturing, and for the world.

There were the big events for the year, including the United States as Partner Country at Hannover Messe in April and the 2016 International Manufacturing Technology Show in Chicago in September. There's also the matter of the U.S. presidential elections in November, which promise to shape policy in manufacturing for years to come.

But the year started with global economic turmoil, as a slowdown in Chinese manufacturing triggered a worldwide stock hiccup that sent values plummeting. The continued plunge in world oil prices has resulted in a slowdown in exploration and, by extension, the manufacture of exploration equipment.
