This drive series is a standard offering on most OEM delivered machines, based on the cost for performance. The feed through wiring...
With the current trend in machine safety being moving towards integrated control and safety functions, Allen Bradley (like most other major suppliers) offers two versions of its main control platforms, the Logix line of controllers. Based on application size and complexity, facilities will use either the CompactLogix or ControlLogix controller platforms for control. Adding safety features onto these controllers, Allen Bradley offers the Compact GuardLogix and GuardLogix (ControlLogix) functional safety rated controllers. As these controllers are updated and improved, there have been several generations of safety rated controllers. With a future trend towards integrating data, safety, and control into one unit for increased productivity, we will continue to see improvements, both evolutionary and revolutionary. The ControlLogix (1756 family) and CompactLogix (1768, 1769, and 5069 families) Programmable Automation Controllers are the primary controllers in Allen Bradley’s offering. The...
The Kinetix family of Motion drives is broken up into several series, each with different focuses. The Kinetix 6000 and its descendant 6200 series are both multi-axis systems utilizing the SERCOS interface for control. Generational improvements in the 6200 series include advanced safety options and a more modular design. Beyond these generational improvements the 6000 and 6200 series are very similar, as the 6200 is designed as a straightforward replacement for 6000 series drives. The Kinetix 6000 series motion drive is a modular, multi-axis, compact servo drive system that reduces required wiring and programming. It’s rated for 1.2 through 22 kW power output, and two nominal voltages – 240VAC and 480VAC in 3 phase configurations.

Both drives utilize functional safety techniques, with Safe Torque Off functionality built in giving them a PLd or SIL2 rating. The differences on the control side for each drive are significant. Both the Kinetix 300 and...
Allen Bradley introduced the Micro 800 family of controllers several years ago, and they are slowly taking over the low-end controller segment for the manufacturer. These controllers are meant for small stand-alone projects, and for OEM’s and machine builders who need a low cost but effective controller. Five series of controllers comprise this family, from the Micro 810 “Smart Relay” to the Micro 870 controller. Each series builds on the previous, with the Micro 820 and 830 series being the smallest of the two (and specialized siblings of each other) and the Micro 850 and 870 including higher functionality and capabilities. All five series in the Micro 800 family have some common benefits. One of the biggest benefits is being able to program and configure the controllers. From the Micro 820 up to the 870, onboard add-on modules allow for additional IO, memory backups, and numerous other higher feature capabilities. Except for the Micro 810, all are capable of some expansion from...
The Allen Bradley PowerFlex 750 series is part of their Architecture Class of drives, higher feature drives for automation projects. They complement the Compact Class drives (PF4x, PF52x) through additional capabilities, although at a higher cost. When looking for a drive solution, these are the Allen Bradley drives to look at when you’re saying terms such as “torque control”, “coordinated drives”, or “almost a servo application”. Both the PowerFlex 753 and PowerFlex 755 drives are capable of torque control, speed control, permanent magnet motor control, and integrated safety (through option modules.) Capability-wise, these drives can compete with any other drives on the market, and their engineering aspects can provide some excellent benefits to the people installing and using them. There are some common features worth noting in the 750 family of drives. Integration into the Studio 5000 programming environment is made easier and more straightforward through use of Add-On Profiles...
In 2016, Rockwell Automation announced an update to their small controller package in the Logix line of controllers, the 5069 CompactLogix controller family. Previously, the CompactLogix processors had been classified under the 1769 (and previously the 1768) family numbers. With the update came several changes, most notably in form factor and performance. The 1769 family of controllers started with the L1x, L2x and L3x, then continued with the 5370 series controllers. These controllers are part of the Logix line of Process Automation Controllers (PAC) from Allen Bradley and are designed to accommodate small to medium sized automation projects. Some common features of the 1769 series are dual RJ45 ports for Ethernet/IP (only a single IP address allowed), LED status indicators on the front of the processor, a USB and SD card port for programming and storage, and a program/run/remote mode switch. Options in the series allow for up to 48 Ethernet/IP nodes, 16 axes of motion, and...
Allen Bradley Powerflex 520 series drives are an innovative take on modular drive configuration.

Today, we’re going to take a look at Allen-Bradley’s popular CompactLogix and ControlLogix processor lines. The ControlLogix and CompactLogix are Allen-Bradley’s most popular lines of Automation controllers. The ControlLogix is designed for larger, more demanding systems, requiring higher I/O counts. The CompactLogix, with its smaller, more affordable frame, is better suited to smaller applications. Here, we will examine the differences in detail. The CompactLogix line sports two variants – modular chassis-free system and all-in-one controller with a chassis. The most popular all-in-one controllers are CompactLogix L23, L1XER, and L2XER. If you’ve used CompactLogix processors, you might have heard of these, as they were best-selling processors in the line. For the modular systems, the L30ER, L33ER, L32X, and L35X are the best-selling components. The packaged CompactLogix processors are ready for work out-of-the-box, which is their main advantage. Conversely, the modular L3 models...
Servo systems are now well-known for their use in CNC machining, robotics, and factory automation. The servo technology is further expanded with the manufacturing of servo drives, used for powering electric servomechanisms. Despite being an excellent option for industry use, we also have these VFDs (Variable-Frequency Drives) which tend to be used a lot as an alternative for servo drives, given their energy-saving potential. Since both of these are widely used in industry and manufacturing processes, it’s important to point out some of the differences between them and in which situations is one better than the other. To do that, we’ll first need to see what are VFDs and servo drives and then compare the crucial differences. A servo drive is an integral part of a servo system that consists of a motor, a controller, a feedback device, and of course – a servo drive. Simply put, a servo drive is a part of the servo system that receives a particular command from a control system, amplifies...
