Troubleshooting and Testing Single Phase AC Motors

Troubleshooting and Testing Single Phase AC Motors

Single-phase motors are common in household and small industrial devices. They are a bit more complex than 3-phase models, so it’s important to recognize failure modes and common symptoms.


Mechanisms Used in Robotic Compliance Devices

Mechanisms Used in Robotic Compliance Devices

Compliance and compensator devices are used in processes where variation and uncertainty are prevalent. What sorts of compliance devices are used, and what distinct advantages are held by each?


Tutorial | First Program Using Rockwell’s Micro800 Series PLC

Tutorial | First Program Using Rockwell’s Micro800 Series PLC

Rockwell Automation’s Micro800 series is the modern replacement for some older MicroLogix PLCs. Learn how to get started with basic I/O, plus timers and counters, to build your own programs in a snap!


Managing Networks | Why Do I Need an Industrial Grade Switch?

Managing Networks | Why Do I Need an Industrial Grade Switch?

I could run down to the local box store or internet marketplace and buy a 5-port switch for less than 20 dollars, or invest in an industrial switch for hundreds. Why would I choose the industrial switch?


Understanding Robotic Force Compensators and Compliance End Effectors

Understanding Robotic Force Compensators and Compliance End Effectors

Force compensators and force compliance end effectors can expand the capabilities of traditional robotics to reach into difficult processes, ranging from grinding and alignment to precision measurement.


PID for Your PLC Using SP and PV. So Many Acronyms, So Little Time

PID for Your PLC Using SP and PV. So Many Acronyms, So Little Time

Implementing PID control in a PLC is far more complicated than textbooks would make it appear. There is more to the process than simply picking gain (k) values and calculating an output value.


Controlling and Troubleshooting Common DC Motors

Controlling and Troubleshooting Common DC Motors

Direct current (DC) motors have existed since the late 19th century. What sets these motors apart from AC models, how do you control them, and how can you tell when it’s time to repair or replace them?


Temperature Profiling: The Process and The Underlying Benefits

Temperature Profiling: The Process and The Underlying Benefits

Temperature profiling is an effective tool to monitor thermal properties in process equipment. This article defines temperature profiling, discusses the process components, and describes the various benefits it offers.


Hands-on Example: Milling Machine Failure Classification Using Logistic Regression

Hands-on Example: Milling Machine Failure Classification Using Logistic Regression

Learn how to build a machine learning model to predict failure classification based on machine parameters using a synthetic dataset modeled after a milling machine, the same process used in real-world systems.


How To: Using Set/Reset Instructions in Mitsubishi’s MELSEC PLCs

How To: Using Set/Reset Instructions in Mitsubishi’s MELSEC PLCs

Setting and resetting a PLC output is essential in establishing a holding circuit for a transducer. Learn how to use set/reset instructions in MELSOFT series GX Works2 to latch and release an output.


Closing the Loop: Feedback, Feedforward, and Adaptive Control

Closing the Loop: Feedback, Feedforward, and Adaptive Control

Process automation relies on precise control systems to operate production equipment for everything from lumber to pastries. Using control algorithms produces stable, accurate, and often delicious results.


Introduction to Transfer Functions for Control System Analysis

Introduction to Transfer Functions for Control System Analysis

Transfer functions allow systems to be converted from non-algebraic time measurement units into equations that can be solved, but how do these functions work, and why do we use them?


Understanding PLC Tags: Controller Scope vs. Program Scope

Understanding PLC Tags: Controller Scope vs. Program Scope

Is it best to ‘controller scope’ or ‘program scope’ your tags? This is the question asked by many new PLC programmers, and it often comes down to personal preference.


Connectors Used in Industrial and Robotic Cable Termination
