Meeting the Challenges of AC-DC Converters for Industrial Applications

Meeting the Challenges of AC-DC Converters for Industrial Applications

Whether the application provides power to an advanced robotic arm for welding or the sensors used in remote condition monitoring, AC-DC converters are a critical design element. The ongoing demand for AC-DC converters has also led to engineering constraints and specifications that these power supply controls must meet.


Understanding PLC Program Commands: Timers

Understanding PLC Program Commands: Timers

The timer is a fundamental function of ladder logic programming. In this article, we discuss on- and off-delay as well as retentive timers and define the inputs and outputs required to properly use them.


Scaling Values: Linear Versus Non-Linear Changes

Scaling Values: Linear Versus Non-Linear Changes

Scaling values has a wide range of applications and helps to match output values to their real-world applications. Most scaling is linear, but many of these real-world changes are not quite so simple.


Plug and Play End of Arm Tooling for Cobot Applications

Plug and Play End of Arm Tooling for Cobot Applications

In the world of modern manufacturing, we want the tools to be effective, safe, and very easy to install and commission. But when we say ‘easy’, how easy can it really be to commission robotic tools?


Power for Control Circuits: It’s Not Just Power Supplies

Power for Control Circuits: It’s Not Just Power Supplies

Power supplies tend to get a reputation as one of the most important power considerations of a DC control circuit - but we can’t ignore other key players: power filters, converters, and backup power modules.


Acoustic Monitoring to Detect Hidden Machine Failures

Acoustic Monitoring to Detect Hidden Machine Failures

Hello acoustics, my old friend. I've come to monitor you again. Because a worn-out bearing softly creeping, slowly got worse while I was sleeping. And the vibration that was planted in my brain still remains… Within the sound of Maintenance


Using AWS Greengrass and SageMaker Tools to Detect Manufacturing Defects

Using AWS Greengrass and SageMaker Tools to Detect Manufacturing Defects

This article discusses Amazon Web Services (AWS), Amazon SageMaker and AWS IoT Greengrass, and how their capabilities at the edge can impact machine learning use cases such as defect defection.


Controlling Hydraulic Devices with Open and Closed Loop Systems

Controlling Hydraulic Devices with Open and Closed Loop Systems

What if you could control the end position and the speed of a hydraulic actuator accurately with just a simple signal? Some systems use simple open/close valves, but others require far more precision.


Variable Frequency Drives: Managing Network Outage Responses

Variable Frequency Drives: Managing Network Outage Responses

Even with the most reliable networks, network outages are inevitable for a host of reasons, and managing these outages in VFD systems becomes critically important.


How-To: Implementing a Data Highway Plus (DH+) System

How-To: Implementing a Data Highway Plus (DH+) System

Allen Bradley’s Data Highway Plus (DH+) networking ability is still found commonly in interfaces with legacy equipment. Understanding this network structure can bridge the gap between old and new systems.


Contactors versus Relays - Differences and Applications

Contactors versus Relays - Differences and Applications

Although the are similarities in operating theory, relays and contactors are used in industrial circuits for different specific applications, and should not be used interchangeably.


Robots and CNC Machines - An Assembly Configuration Made in Heaven

Robots and CNC Machines - An Assembly Configuration Made in Heaven

Our own Control Automation engineering staff had the opportunity to visit VersaBuilt, a CNC robotic integration shop offering an application system from the Universal Robots UR+ series.


The Cat’s Out of the Bag - Demystifying Network Cables

The Cat’s Out of the Bag - Demystifying Network Cables

What’s the difference between a Cat 6 and a Cat 6a cable, anyhow? Ethernet cables must meet certain performance standards, and these standards can be quite confusing at first glance.


Hysteresis - Error and Compensation in Control Systems

Hysteresis - Error and Compensation in Control Systems

Hysteresis is a term introduced in basic control system courses and listed on sensor datasheets, but the terms is not often understood, with error deriving from both the system itself as well as the sensor.


Comparing Mechanical vs Hydraulic Forces

Comparing Mechanical vs Hydraulic Forces

In honor of May the 4th, Star Wars Day, we compare the sources and applications of the two most common force-delivery systems - mechanical and hydraulic.


Up Close and Personal With Automated Ag Equipment

Up Close and Personal With Automated Ag Equipment

Our Control Automation engineering staff got the chance to visit a commercial farm in North Dakota and learn the hardware and software making these huge automated tractors ready for high-tech ‘field’ work.


Siemens SIMATIC PLCs - Hardware History

Siemens SIMATIC PLCs - Hardware History

In this first of an upcoming series, we investigate Siemens as a major PLC manufacturer, learning about the hardware, software, and key applications of each product lineup.


Circular Economy - Manufacturing to End User… And Back

Circular Economy - Manufacturing to End User… And Back

‘Reduce-reuse-recycle’ is a common slogan for promoting reduction of waste associated with end use of materials. But a circular economy model includes manufacturing processes and raw materials as well.


Epson Robot Programming Example

Epson Robot Programming Example

Epson robot programming bears similarities to other industry-standard brands, but contains many unique features, including the ability to run background programs alongside the main function.


Defining Scalar and Vector Control in VFD Outputs

Defining Scalar and Vector Control in VFD Outputs

Two common methods exist for driving induction motors with VFDs - linear scalar control, which is often labeled as V/f, and vector, or field-oriented control, which can be a bit more complex to understand.
