How to select a VFD for a motor is an important question for many engineers and plant operators. An alternating current (AC) induction motor’s speed can be controlled with a Variable Frequency Drive (VFD). VFDs are widely used when a motor does not always need to run at full speed,…

A well-structured VFD preventive maintenance checklist is essential for keeping your drives operating at maximum efficiency. With variable frequency drives (VFDs), preventive maintenance is essential to maintaining your equipment in optimal working order. These devices are significant investments; therefore, maintaining their functionality is essential to earning a healthy profit. To…

VFD motor overload fault is one of the most common issues encountered in industrial applications where variable frequency drives (VFDs) are used to control motor performance. When an overload occurs, it can affect system efficiency, reliability, and even safety. In this article, we explore the root causes, operational impacts, and…

What is VFD tripping on overcurrent? When a frequency converter senses an excessive current flow, it trips, preventing harm by initiating a preventive shutdown.  Finding the underlying causes of such accidents is made possible in large part by fault analysis.  Operators can preserve system effectiveness, minimize downtime, and guarantee the…

What causes a VFD to trip? Keeping a VFD clean, cool, and dry is important, but it’s not always enough. Even well-installed drives can suddenly stop, leading to unplanned downtime and costly interruptions. In this guide, we’ll break down the main VFD trip reason, explain the most common failures, and provide…
