Default configuration

ABB · ACS850 Standard Program Firmware

What does 8 mean?

The drive is stuck in its default configuration state during boot-up, rather than progressing to an operational state. While a normal temporary boot state, persisting in this state indicates an underlying hardware or configuration problem, potentially preventing the drive from enabling or communicating.

Common Causes

  • Corrupted non-volatile memory (NVRAM) where drive configuration parameters are stored, causing it to revert to factory defaults.
  • Failure to load parameters from an external memory device (e.g., SD card) or a connected PC during boot.
  • Firmware incompatibility issues after an update, preventing parameters from being correctly interpreted or applied.
  • A fault during the power-up sequence that prevents the drive from loading custom parameters.
  • Incorrect setting of a critical boot parameter (e.g., Parameter P0-00 for restore defaults) preventing normal startup.

Repair Steps & Checklist

Click steps to track your progress.

  1. 1

    Connect to the drive using commissioning software (e.g., Mint Workbench) and attempt to upload the drive configuration file. If successful, save the configuration.

  2. 2

    Perform a factory reset of the drive (e.g., using Parameter P0-00 or a specific HMI sequence) to clear any corrupted settings.

  3. 3

    Re-download a known good configuration file to the drive from a backup.

  4. 4

    Verify the firmware version matches the installed hardware and is compatible with the configuration file being used. If a recent firmware update occurred, roll back or re-flash.

  5. 5

    Check the status of any external memory cards (e.g., SD card) if used for parameter storage; ensure it's not corrupt and correctly inserted.
