EFB config file

ABB · ACS580

What does 6682 mean?

The embedded fieldbus (EFB) configuration file could not be read by the drive. This indicates a potential issue with the EFB's internal software or memory where its settings are stored, preventing it from initializing or operating correctly.

Common Causes

  • Corrupted or missing EFB configuration file in the drive's internal memory (e.g., during firmware update, power interruption).
  • Incompatible firmware version between the drive and the EFB module, preventing correct loading of the configuration.
  • Hardware fault with the drive's internal EFB module or its memory component.
  • Improper initialization or reset sequence of the EFB module.
  • Incorrect drive replacement without transferring or re-uploading the EFB configuration.

Repair Steps & Checklist

Click steps to track your progress.

  1. 1

    Perform a parameter upload from the drive's memory to a PC tool (e.g., Drive composer) and attempt to re-download the EFB configuration parameters (e.g., P53 group).

  2. 2

    Initiate a factory reset of the drive (e.g., P99.02 set to 3 for parameter restore) and re-enter all critical parameters including EFB settings.

  3. 3

    Check the drive's firmware version and compare it against the recommended firmware for the installed EFB features; update if necessary.

  4. 4

    If a removable memory unit (e.g., SD card) is used for EFB configuration, ensure it is properly inserted and not corrupted.

  5. 5

    Contact manufacturer support with drive serial number and EFB module details for advanced diagnostics or potential hardware replacement.
