When selecting a soft starter for your motor control application, it helps to know what each setting does and how it affects your motor’s behavior. However, as different modes and features are added to a soft starter, it can be a bit overwhelming to determine the optimal choice for your application. After all, there is kick start, current ramp, torque control, linear acceleration, full-voltage start, and more. Today we will narrow down this list and go over the two more popular starting modes, voltage ramp and current limit start, explain what makes them different, and even why they might be used together. Order SMC Flex Soft Starters Here Before we dive into how these soft starter features work, it helps to first briefly go over what a soft starter is and does. If you would like a much more in-depth explanation and overview, we encourage you to read our full guide to soft starters here . The general idea of a soft starter is to place this device between an induction motor and its...
When it comes to PowerFlex drives, the gap between the most cost-effective model and the most technologically advanced unit is quite significant. From the humble PowerFlex 4M and 520-series controllers offering simple and dependable motor control, to the flagship PowerFlex 755T family built with smart features in mind for demanding applications. Technically speaking, both ends of the lineup are doing the same basic job. They take incoming electrical power and control how it’s delivered to the motor. But that’s like comparing a 20-year-old work truck and a newer, fully equipped heavy-duty model. Sure, both can get you down the road, but one is designed to handle a much wider range of conditions, loads, and specialized tasks. It’s this gap that makes the PowerFlex line interesting to compare. Moving from an entry-level drive to a high-performance model doesn’t just add a few settings or a larger enclosure, but rather more sophisticated motor control, beefed-up hardware, and a suite of...
For more than 20 years, one of the most extensively used programmable logic controller (PLC) platforms in small and medium-sized industrial facilities has been the MicroLogix family, which includes the 1000 , 1100 , 1200 , 1400 , and 1500 series. Each MicroLogix controller combines the CPU, power supply, communication interfaces, and fixed or semi-modular input/output (I/O) into a single chassis, making it a small, self-contained automation system. MicroLogix streamlines installation, minimizes cabinet space, and reduces overall system complexity compared to modular PLC systems like CompactLogix and ControlLogix, which distribute these components across a backplane. By enabling modest extension with Bulletin 1769 Compact I/O modules, the MicroLogix 1500 further increases versatility. MicroLogix controllers have enough processing power for a variety of industrial applications, while being small by today’s standards. They handle 16 to several hundred discrete I/O points, provide between...
