For well over 30 years, variable frequency drives (VFD) have been controlling the speed of three-phase alternating-current (AC) induction motors. In addition to saving energy, there are many things to consider for maximum efficiency, control, operation and motor life when using VFDs.

Automating Hazardous Gas Delivery
When a highly flammable, toxic and corrosive gas delivery system for semiconductor production tools became unreliable, Headway Technologies contracted with system integrator KCC Software for the needed upgrades. KCC Software’s experience and expertise led to the successful replacement of a failing automation system with a new automatic gas control (AGC) system.
It is often difficult to find internal resources to complete an industrial automation project. There are many reasons, such as time limitations and other constraints, so the solution often involves the use of external resources from a system integrator (SI). There are many decisions and requirements to consider when selecting a system integrator, and the…
It’s 5AM and you slowly realize the all too familiar sound of your alarm clock yelling at you to get out of bed. It’s Monday morning, time to throw on something you’ll realize later you forgot to iron, swallow some coffee and jump into the car for your long commute to the office. There are…
AutomationDirect considers itself a strong community partner, and one of our favorite community activities is sponsoring after school competition robotics programs. Why? Because it does such a great job of getting young minds engaged in learning. Attitudes change from “Why do I have to learn this science and math stuff?” to “Oh! I need to…
What may seem to be a simple task of selecting a soft starter for your motor may be a more demanding task than first meets the eye. “I just need to know the HP and Voltage to pick the correct one, isn’t that right?”
Sensors and transmitters convert a variety of physical properties into discrete and analog signals for use by automation controllers. AutomationDirect offers an assortment of these devices for use in the design and operation of machines and processes to create reliable, robust and consistent automation. It may only take a small change in a physical property…
Locking tongue operated safety interlock switches provide a tamper-resistant actuator mechanism for sliding or lift-off machine guards, as well as a method for locking the guards in place. They also provide robust position interlock detection and locking for moving guards. Safety switches offer positively operated switching contacts for maximum reliability.

Ethernet Basics
Ethernet has become a prominent method of communication in industrial automation. Its ease of use, speed, and versatility have allowed it to surpass the older, closed-off, proprietary means. Not only that, but Ethernet has also introduced automated systems to a whole new world of possibilities with connections to high-level IT systems, remote/mobile access, cloud computing,…

Ethernet Dos and Don’ts
With the popularity of the Industrial Internet of Things (IIoT), industrial Ethernet applications are expanding. The IIoT is helping collect data on plant floors and is using Ethernet cables, connector and switches as key components. Industrial protocols such as Modbus TCP/IP and EtherNet/IP help connect edge devices and instruments to controllers and HMIs. Not only…
