It’s easy to get carried away by the shiny parts and robotic movements in automation. After all, what’s the first thing you think of when you hear “automation”? Is it a bottling plant? A palletizer, perhaps those robotic floor waxers at your local grocery store? There is so much on the surface looking in that it’s easy to ignore the guts within that make it all possible, especially when they’re designed to be so compact and hidden away. We’re talking about the PLCs, drives, and motors that make it all move, specifically a family of PLCs called MicroLogix by Allen-Bradley. These kinds of PLCs aren’t designed to dazzle with flashy features but are built with a reputation for reliability and compact form factors. They’re exactly the type of PLC you would depend on for moving water from a reservoir, coordinating a conveyor in a warehouse, or even running in pharmaceuticals. Applications where these MicroLogix PLCs could be found are just what we’re going over today. We will break down the...
CNC is an incredible feat to reach in fabrication and the general industry. It brings unmatched precision and speed to products that demand tight tolerance or repetitive machining. While the software side is very impressive, the heart of the machine lies in the spindle motor. After all, it’s what brings the cutting tool to life, transforms a block of raw material into a finished part, and makes automation in machining more than programmed movements. But just what makes a good spindle motor, and more importantly, how does it bring a CNC machine from G-code to finished parts? Let’s find out! At its simplest, the spindle is the carrier of the cutting tool. When you see a CNC machine boring a hole, milling a pocket, or cutting a contour, the spindle is what’s physically holding that tool in place and delivering the rotational motion needed to cut. Bearings inside the spindle assembly allow it to spin freely, while housings and supports keep it aligned and rigid. But the spindle itself...
AC drives, often referred to as variable frequency drives or VFDs, are essential for regulating motor speed, increasing energy economy, and facilitating better process control in industrial environments. Their lifespan may be shortened or they may fail when utilized in severe situations, such as outdoor spaces, humid industrial facilities, or dusty plants. When installing AC drives in these situations, cooling systems and Ingress Protection (IP) ratings are two important considerations. Any industrial setting where environmental factors have the potential to harm or interfere with electronic equipment is considered a hostile environment. Examples include caustic chemical facilities, humid food industries, dusty cement plants, and outdoor sites subjected to severe weather conditions. Drive dependability might even be impacted by vibrations from heavy machinery, like mining. Drives must be safeguarded in these circumstances to prevent problems and expensive downtime. Ingress Protection...

When it comes to making a new product, a few design pillars need to be followed to make it successful. Some of which are that the product must be reliable, have a quality design, be cost-effective, and have good safety standards. So when building with already existing products, picking the right components is, obviously, essential to meet those requirements. In the case of using drives, picking one out with good headroom, small form factor, and just the right amount of features can help reduce the cost of an OEM design. This is where drives like the PowerFlex 40P series come into play. It offers competitive motion control while maintaining a small form factor and a lower price. But just what makes it good for OEM designs? Well, let’s show you. Space is a premium in assemblies, especially for OEMs trying to fit drives into pre-designed enclosures, panel-mounted boxes, or machines with strict dimensional limits. The PowerFlex 40P addresses this head-on with a variety of flexible...
There’s a very important rule of thumb when dealing with equipment, or really anything: If it isn’t broken, don’t fix it. In the case of the Kinetix 6000 , they’re built like tanks and just keep working. In fact, no one would be surprised if you find them humming away in plants that haven’t touched a firmware update since flip phones were a thing. Shop for Kinetix 6000 Drives Here But as technology progresses, whether it be for tighter safety regulations, smarter diagnostics, the shift to Ethernet/IP, or touch screens in the case of flip phones, it’s not a bad idea to start asking: should we just expand what we’ve got, or is it time to move on? This is where the Kinetix 6200 and 6500 come into play. While they aren’t flashy replacements, they’re more of a logical step forward. With it, you retain the SERCOS backbone and power rail, but add modularity and safety where it matters. The 6500 represents a definitive step forward, offering full EtherNet/IP motion control and integrated...
As a wise person once said, “Communication is key.” While you may have heard that this is the case for various reasons, it rings true when discussing automation equipment, specifically the fieldbus. Some plants speak EtherNet/IP while others may stick with Profibus. Some even still shout in DeviceNet, as if it were 2004. The PowerFlex 750, being the multilingual powerhouse that it is, will listen, translate, and keep everything running smoothly. With a lineup of swappable communication modules and native Ethernet/IP on board, it fits in whether your plant is state-of-the-art or still catching up.

The PowerFlex 40P is an upgrade from the tried-and-true PowerFlex 40. It offers closed-loop feedback, 80:1 speed regulation for finer adjustments, and the ability to use feedback devices like incremental encoders. This also opens the door to more possibilities for motion control that weren’t available to the standard 40 series. While this won’t be a comparison guide between the 40 and the 40P, we actually do have one that you can check out over here . Before diving into what this drive could do, it’s best to lay out the foundation for the specs and numbers that this drive puts out. Power-wise, you’re looking at 0.4 to 11kW (0.5 to 15 HP) and in voltage classes of 240, 480, and 600 volts. Beyond the power ratings, the 40P also supports vector control with encoder feedback to give you tighter control over torque and speed than the scalar-only PowerFlex 40. This makes the 40P ideal for applications that demand accuracy, repeatability, and where variable loads are in play. While it isn’t...
Packaging lines are a kinetic industrial art show. Each movement of the system is precise, calculated, and performed without the slightest hint of hesitation. Each stage of the performance, from unfolding packaging boxes to the way that a robot arm would tilt the product just slightly into the box before loading it in, demonstrates the ingenuity and forward thinking that is demanded when putting together a system like this. If a beat is missed, the infeed roller stutters, or the sealer jaw closes half a second too early, you don’t just get a crumpled bag; you get downtime, wasted film, product jams, and a line operator with a headache. Coordinated motion is what keeps everything humming, every component moving in sync with the others, like gears in a watch. And for many systems out there, it’s the Kinetix 6000 quietly running that shows. They are tried and tested, and they still take up coordinated motion tasks, and here’s why. Coordinated motion is about precise, predictable...
No matter what industry you look at, three consistent challenges are always working to be improved: How to make the plant more energy efficient, reduce downtime, and optimize productivity. We are going to home in on reducing downtime with the help of some very cool features of modern drives. This list will mostly focus on Allen-Bradley’s technology and drives to serve as examples of what modern equipment can do to save money and time by helping prevent unplanned downtime. Predictive maintenance is a powerful utility introduced with AB’s proprietary TotalFORCE technology in the 755TS and 6000T series VFDs. When enabled, the drive will continuously monitor itself and the motor it is controlling’s parameters, such as heat levels, component runtime hours, mechanical stress or wear, electrical anomalies, or blown fuses and internal faults. The drive will anticipate if the component is about to fail and even estimate how long it has until it’s nearing its operational end of life. This...
No matter the purchase, reliability is often one of the top deciding factors, and when it comes to automation, it’s tied directly to uptime and maintenance costs. When considering an automated process, reliability prevents costly downtime and unexpected repairs. Even a robust motor can break down if it’s subjected to the wrong startup conditions or poorly configured controls. Likewise, many different features and options are meant to prevent damage to the motor and keep it running as smoothly as possible. Some modern drives will even estimate the end of life for your equipment. Today, we will explore the features and options available with modern AC drives, specifically the PowerFlex series by Allen-Bradley, and explain how they help prevent unnecessary motor damage. Overload protection is a fundamental feature in modern drives that helps guard against prolonged overcurrent that can overheat the motor windings. If this overcurrent condition persists for too long, the drive will trip...
If you’ve spent any time around industrial DC motor systems, chances are you’ve crossed paths with the Bulletin 1395. Big, rugged, and almost deceptively simple, these drives were the workhorses of their day, handling anything from steel rolling lines to hoists and winders with little more than a hum and the occasional fan whine. The 1395 was the standard for years, not because it had bells and whistles, but because it didn’t need them. It worked, and it kept working. But time moves on, and so does technology. Allen-Bradley’s PowerFlex DC drive lineup is the natural successor to the 1395, designed not just to replace it, but to rethink what a DC drive can offer in terms of performance, integration, and long-term reliability. That’s not just about throwing in a few extra features or making the packaging smaller. It’s about re-engineering the entire control experience while still serving the same heavy-duty applications. Of course, it’s one thing to say something is “modernized” or...
