Variable Frequency Drives (VFDs) are designed to improve efficiency, protect equipment, and give operators precise control over motor-driven systems. But in the field, we see a different reality far too often—systems underperforming, failing early, or causing unnecessary downtime. In most cases, the issue isn’t the drive itself. It’s how it’s installed, programmed, or maintained. Here are five of the most common—and costly—mistakes we see in real-world applications. 1. Incorr

If you manage a facility, you already know this: VFD failures never happen at a convenient time. They happen: During peak production Right before a deadline Or late on a Friday when support is hard to reach And when they do, it’s not just a repair, it’s lost time, lost output, and mounting pressure . The good news?Most VFD failures don’t come out of nowhere. They leave clues. 1. Intermittent Fault Codes That “Clear Themselves” If a drive throws a fault and then resets… it’s e

When it comes to keeping your Variable Frequency Drives (VFDs) running smoothly, most maintenance teams think about software updates, cooling fans, or maybe dusting out the enclosure. But there’s one simple maintenance step that’s often overlooked, and it can dramatically extend your VFD’s life and reliability: regular capacitor health checks. Why Capacitors Matter Inside every VFD, capacitors play a crucial role in smoothing out DC voltage and maintaining consistent power t
