#vfdtripping

VFD tripping on overcurrent is one of the most frequent and critical faults encountered in industrial environments. It usually means your Variable Frequency Drive is detecting a current level that exceeds the safe operating limit — and it shuts down to protect the motor and the drive itself.

But what actually causes this fault? It could be a sudden change in load, a locked rotor condition, poor motor connections, or even a misconfigured acceleration time. Sometimes it’s as simple as a mismatch between the motor and the drive’s rated current.

In real-world field service, engineers often face this issue under pressure — especially when downtime is expensive. That’s why having a step-by-step troubleshooting checklist is essential.

In our latest guide, we walk you through: ✅ Common causes of overcurrent trips in both low and medium voltage VFDs ✅ How to inspect the load, motor, and wiring safely ✅ Which drive parameters to review and adjust ✅ Real examples from field troubleshooting

Whether you're working on HVAC systems, conveyor motors, or heavy-duty pumps, this guide will help you isolate the root cause and avoid unnecessary shutdowns.

VFD tripping isn't random — it's a warning. From parameter issues to ground faults, one wrong setting can stop the entire system.

This post explores the common causes of VFD tripping and gives you practical steps to troubleshoot faults before they become critical.
