Internal Fault (HMI Card)

Schneider Electric · Altivar 312 Variable Frequency Drive

What does IF2 mean?

This internal fault indicates an issue with the Human Machine Interface (HMI) card, such as it not being recognized, being incompatible, or the display being absent. While the drive might still be functional, the lack of a working HMI prevents local monitoring, parameter adjustment, and control, hindering operation and troubleshooting.

Complete Troubleshooting Guide

  1. 1

    Ensure the HMI card is securely seated and properly connected to the drive.

  2. 2

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

  3. 3

    If the fault persists, replacing the drive or the HMI card (if modular) may be necessary.

  4. 4

    Contact a Schneider Electric representative for further assistance.
