Negative Effects of Grounding (Earthing) a DC Power Supply

Negative Effects of Grounding (Earthing) a DC Power Supply

DC voltage systems exist to provide controllers and field devices with stable power, but it is not always clear when these systems should be bonded with the earth ground of the AC line voltage supply.


Obsolescence in Control Systems - Disaster or Opportunity?

Obsolescence in Control Systems - Disaster or Opportunity?

One of the most considerable risks in aging control environments is that eventually, spare parts become obsolete and unavailable, and the lack of an upgrade plan can turn a simple failure into a catastrophe.


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.


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?


DC Motors - Why Are We Still Using Them?

DC Motors - Why Are We Still Using Them?

AC motors are common throughout industry - easily controlled by VFDs and without the maintenance that comes with DC brushes. So then, why are DC motors still used in certain applications?

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.
