E.LUP

Upper limit fault

Mitsubishi · FR-E800 Variable Frequency Drive

What does E.LUP mean?

The inverter output is shut off when the load on the motor exceeds the defined upper limit fault detection range. This is a protective function to prevent damage from excessive loading, active only when Pr.1490 is not set to '9999'.

Complete Troubleshooting Guide

  1. 1

    Inspect the equipment to determine if excessive load is being applied to the motor.

  2. 2

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