Lower limit fault

What does E.LDN mean?

The inverter output is shut off when the load on the motor falls below the defined lower limit fault detection range. This protective function detects abnormally light load conditions, potentially indicating a mechanical issue or a disconnected load, and is active only when Pr.1491 is not '9999'.

Complete Troubleshooting Guide

1. 1

   Inspect the equipment to determine if the load is too light, potentially due to a mechanical failure or disconnection.

2. 2

   Verify and correctly set the load characteristics parameters (Pr.1481 to Pr.1487) to match the application's normal operating range.
