IF3

Internal Fault (EEPROM)

Schneider Electric · Altivar 312 Variable Frequency Drive

What does IF3 mean?

This internal fault indicates an issue with the drive's internal EEPROM memory. Similar to EEF, this points to potential data corruption or a hardware failure within the non-volatile memory storing operational parameters. Such a fault can compromise drive stability, lead to incorrect settings, or cause operational failure.

Complete Troubleshooting Guide

  1. 1

    Restart the drive by cycling its power (turn off, wait, turn on).

  2. 2

    If the fault persists, the drive should be replaced due to internal hardware failure.

  3. 3

    Contact a Schneider Electric representative for further assistance.
