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.


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.


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.

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.


Dynamic Braking Resistors for Motor Control Applications

Dynamic Braking Resistors for Motor Control Applications

Large DC and AC motor drives often provide terminals for installing a braking resistor. What are these resistors, and how do they slow down a machine? What hazards and cautions must be considered?


Introduction to Safety Relays

Introduction to Safety Relays

Redundancy and safety are often seen together in industrial safety systems. Safety relays monitor emergency devices to switch contacts based on status - but what makes them different from normal relays?


Mechanisms of Linear Sensing and Linear Encoding

Mechanisms of Linear Sensing and Linear Encoding

Linear sensors use electrical means to determine their position. Common linear position sensors are resistive, inductive, capacitive, and many rely on a property called magnetostriction.

Info Byte: What’s the Deal With Debouncing Switches?

Before digital control systems, responses were fairly slow. Push a button, and a motor contactor engaged. These days, the speed of computers introduces some new challenges but brings solutions as well.


My First Experience Programming a Collaborative Robot

My First Experience Programming a Collaborative Robot

We've read about the capabilities of collaborative robots, but often, one question still remains - how do you program a cobot? Last week, I got a chance to get my hands on a cobot for the first time.


Understanding the Basics of Pulse Width Modulation (PWM)

Understanding the Basics of Pulse Width Modulation (PWM)

Power delivered to devices can be changed by raising or lowering the voltage and current. But this method does not always produce intended results. Pulse width modulation (or PWM) can be used to better control variable loads.
