E.IOH

Inrush current limit circuit fault

Mitsubishi Electric · FR E700

What does E.IOH mean?

This fault stops the inverter output because the resistor of the inrush current limit circuit has overheated. Frequent power ON/OFF cycling is a common cause, stressing the components. Overheating can lead to component failure and damage to the inverter.

Complete Troubleshooting Guide

  1. 1

    Modify the system to prevent frequent power ON/OFF cycles of the inverter.

  2. 2

    If the fault persists despite correcting power cycling behavior, contact your sales representative for further investigation.
