External Storage

What does F101 mean?

The external non-volatile storage, often used for backing up or expanding parameter storage, has failed. This fault indicates a problem with the memory component where drive settings are permanently saved, potentially leading to lost configurations or inability to save changes.

Complete Troubleshooting Guide

1. 1

   Set parameter P053 [Reset To Defalts] to '2' ('Factory Rset') to attempt to clear the fault and reinitialize the storage system.

2. 2

   If an external memory module (e.g., HIM, SD card) is used, ensure it is properly inserted and not corrupted.

3. 3

   Reprogram any lost parameters after the reset or attempt to restore from a known good backup.
