Inverter overload

What does 9 mean?

The frequency converter has been operating at more than 100% overload for an excessive period and is about to trip. A warning is issued at 98% overload, and a trip (alarm) occurs at 100%. The frequency converter cannot be reset until the internal thermal counter drops below 90%.

Complete Troubleshooting Guide

1. 1

   Reduce the mechanical load on the motor and driven equipment.

2. 2

   Inspect the motor and mechanical system for any binding, excessive friction, or blockages that could increase load.

3. 3

   Verify that the motor parameters (e.g., nominal current, voltage, frequency) programmed in the drive match the motor's nameplate data.

4. 4

   Consider upsizing the drive or motor if the application consistently requires more power than current components provide.
