Load fault warning

What does LDF mean?

This warning appears when the current load on the inverter deviates from the detection width defined by Pr.1488 (Upper limit warning detection width) or Pr.1489 (Lower limit warning detection width). It indicates an unexpected load condition, either too heavy or too light, potentially due to equipment issues.

Complete Troubleshooting Guide

1. 1

   Inspect the equipment to determine if an excessive or insufficient load is being applied.

2. 2

   Verify and correctly set the load characteristics parameters (Pr.1481 to Pr.1487) to match the application.
