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. Let’s take a look at just what the 750 series can do. Shop for PowerFlex 750 Series Drive Accessories Here The 755 includes an Ethernet port out of the box, providing native support for topologies such as Device Level Ring (DLR) and CIP protocol. This makes Ethernet/IP the easiest way to get a 755 talking to a Logix controller. It handles everything from speed reference to status monitoring...
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...
As time goes on, the drives that were originally new and modern soon become outdated and obsolete. New safety standards are being rolled out, different communication protocols have proven to be much more effective, and better software and hardware technology are ushering in a new era of smart factories. The question then becomes whether it is worth upgrading to a new, modern system, trying to retrofit modern equipment, or sticking with the old and keeping it running for as long as possible. Such could be the case for the 1336 Plus II. Today, we would like to provide some thought-provoking insight into a tough question that may need to be answered sooner rather than later: Should you keep or replace your 1336 Plus II system? When a factory decides to keep its 1336 Plus II drives, it’s usually not because it doesn’t know what a modern drive can offer but because its current system works in a way that’s tough (or expensive) to replace. However, there is usually a bit more to it than...
The argument between DC and AC drives is still being debated in motor control and industrial automation. Although AC drives are now the norm in many applications because of their cost-effectiveness, efficiency, and reduced maintenance requirements, DC drives—especially Rockwell Automation’s PowerFlex DC drives—still perform better in some situations. This article examines those particular use cases, emphasizing PowerFlex DC drives’ special benefits and why they are essential to several industrial settings. Shop for PowerFlex DC Drives and Parts Here It’s critical to understand the basic distinctions between AC and DC drives before delving into the application cases: By altering the frequency and voltage applied to the motor, AC drives regulate the speed of an AC motor. By modifying the armature voltage and, occasionally, the field current, DC drives regulate the speed of a DC motor. DC drives provide greater torque control, easier speed regulation, and better performance at low...
