The Good, the Bad, and the Ugly: Using Frequency Filters for Control Systems

Frequency filters remove unwanted variations from signals and power sources. In this article, we explore why we need frequency filters in industrial automation and where they are commonly found.


Industrial Networks: “Protocol over a Standard?”

Industrial Networks: “Protocol over a Standard?”

Industrial communication channels often contain terms such as ‘Modbus over RS485’ or ‘CIP Safety over Ethernet’. What does it mean to send one network over another, and how does it work to your advantage?


Automated and On Track: What is Total Laboratory Automation?

Automated and On Track: What is Total Laboratory Automation?

Total laboratory automation (TLA) helps in workforce utilization, reduced costs, and management of routine testing. Learn about what TLA is, its components, and what to consider before replacing a traditional laboratory.


Teardown: What’s Inside a Variable Frequency Drive (VFD)?

Teardown: What’s Inside a Variable Frequency Drive (VFD)?

Variable frequency drive units can be found inside tons of control cabinets, but what happens if you disassemble one to see what’s inside and how it works? We did just that. The results might surprise you.


Know Your Phase: How and When to Use a Motor and Phase Rotation Tester

Know Your Phase: How and When to Use a Motor and Phase Rotation Tester

Connecting a new motor without knowing the phase rotation of the electrical supply can cause damage to expensive equipment. By using a 3-phase rotation meter, you can save yourself time and money.


What You Need to Know: Variable Frequency Drives (VFDs)

What You Need to Know: Variable Frequency Drives (VFDs)

With precise control abilities to manage speed, torque, and direction, variable frequency drives remain one of the most common methods of driving 3-phase industrial motors. Below, we introduce a few leading VFD manufacturers.


Understanding and Using Safe Torque Off (STO) for Motion Systems

Understanding and Using Safe Torque Off (STO) for Motion Systems

Safety is one of the most critical aspects of machine design. Today, with network connections between different machines and control centers, safety signals must be shared logically and reliably across networks.


Proportional Gain and Proportional Band Explained

Proportional Gain and Proportional Band Explained

Learn about proportional gain and proportional band, two key proportional control concepts, to better understand the most popular control system method in industrial automation.


Fatigue Failures in Amorphous Materials

Fatigue Failures in Amorphous Materials

Fatigue failures in amorphous materials have long been a bit of a mystery in the engineering and scientific fields, but new research is removing some of the mystery and may open up new applications for amorphous materials.


Feedback for Fluid Cylinders: Bang Bang Control

Feedback for Fluid Cylinders: Bang Bang Control

Tracking the position of a hydraulic or pneumatic cylinder is often accomplished at a basic precision level, detecting only end stop limits with discrete digital values… But what methods accomplish this?


Sine/Cosine Approximations Simplify Controller Operation

Sine/Cosine Approximations Simplify Controller Operation

Programming languages often include sine and cosine functions. They simplify programming, but consume valuable memory space and computation time. This can be overcome using simple approximations.
