Reducing Power-On/Off Glitches in Precision DACs: Part 2

Part 1 of this article introduced a phenomenon called power-on/off glitch. The example discussed the impact of this phenomenon on a motor control system. We limited our analysis to a DAC where the output buffer is powered on in normal mode: zero-scale or mid-scale. In Part 2, we analyze when the DAC output is powered on in high-impedance mode. We present a mathematical model for the power-on glitch, followed by board-level solutions to minimize it.

Autonomous Robots Keep Warehouse Running Green

YLOG, a startup company in Austria, uses an intelligent and very environmentally friendly logistics system that is winning an increasing number of customers. The technology makes use of individual, freely moving Autonomous Intelligent Vehicles (AiVs) that detect each other, observe right-of-way rules, recognize one-way routes, and complete their tasks fully autonomously without intervention from or coordination by a central computer.

PLC-Based Robotic Controls Versus OEM Robotic Controls

As more manufacturing facilities and distribution centers discover the benefits of robotic material handling solutions, the decision of how best to control the robot must be made. While robot original equipment manufacturers (OEMs) offer their own tightly integrated controller, recent developments have enabled control by a Programmable Logic Controller, or PLC. For facilities where PLC-based controls are already used in other machine control applications, the benefits of using one for the robot as well may be a wiser choice than the OEM controller. Let’s review PLC-based robotic control to help you determine if it’s the best choice for your application.

The Less is More Approach to Robotic Cable Management

In recent years, cable management has come into the limelight because machine reliability has increased dramatically, even though robots have grown more complex. Unfortunately, the methods used to attach and guide cables have not quite followed suit. While managing cables and hoses is often an afterthought in most designs, it is truly a vital part of any well-functioning robot.

Energy Chain® Cable Carriers: The Right Material for Any Application

Cable carriers are often an afterthought for many design engineers, but many times, they are the key to protecting vital cables and hoses on automated machinery. Cable carriers can be considered the lifeline that keeps a machine running. They not only guide the cables and hoses, but protect against harsh external elements, including dirt and dust, flying debris, chemicals and excessive heat.

TechTalk Design Advice Series: The Cable Distribution Rules You Need To Obey

The key advantage of a cable carrier is that bus and motor cables, pneumatics, electrics and hydraulics can all be guided safely in one system. However, correctly arranging each cable and hose within your chosen cable carrier according to the recommended spacing requirements is vital if you want to prolong the service life of your system.
