E ngineers looking for more precise control than the average smart amplifier can deliver should consider the SB1291single axis motion control module for brush, ac-servo, and ac-induction motors. According to ACSTech80 Marketing Manager Curt Prins, it's a cost-effective combination of an advanced programmable motion controller, an all-digital drive, and a power supply.
The unit employs dual-processor architecture that devotes a servo processor (DSP) to execute the real-time control algorithms and an Intel-based motion processor unit (MPU) to manage other activities. The universal controller is software configurable for dc brush, ac servo (ac synchronous), and ac induction motors and features automatic sinusoidal commutation setup for any three-phase motor.
Available in two power levels, 24 to 60V dc, 7.5A (15A) and 120V dc, 5A (10A), the differentiator between this and similar products on the market is reportedly controller capability. "Most suppliers of controller and drive products were in the drive business first. In contrast, we've been a controller company from the start, so our advanced programming adds to the controller's flexibility in more demanding applications," says Prins. For example, its Position Event Generator (PEG) function generates position triggered events with very small (electronic gate) delays, which is useful in scanning applications where it is necessary to activate external events based on position such as high accuracy laser.
Robots that walk have come a long way from simple barebones walking machines or pairs of legs without an upper body and head. Much of the research these days focuses on making more humanoid robots. But they are not all created equal.
The IEEE Computer Society has named the top 10 trends for 2014. You can expect the convergence of cloud computing and mobile devices, advances in health care data and devices, as well as privacy issues in social media to make the headlines. And 3D printing came out of nowhere to make a big splash.
For industrial control applications, or even a simple assembly line, that machine can go almost 24/7 without a break. But what happens when the task is a little more complex? That’s where the “smart” machine would come in. The smart machine is one that has some simple (or complex in some cases) processing capability to be able to adapt to changing conditions. Such machines are suited for a host of applications, including automotive, aerospace, defense, medical, computers and electronics, telecommunications, consumer goods, and so on. This discussion will examine what’s possible with smart machines, and what tradeoffs need to be made to implement such a solution.
