CFF

INCORRECT CONFIG.

Schneider Electric · ATV32HD11N4 Variable Speed Drive

What does CFF mean?

This fault indicates that the current configuration loaded into the drive is inconsistent, possibly due to the addition or removal of an option card without proper configuration updates. An inconsistent configuration can lead to unpredictable drive behavior, prevents proper operation, or can cause other faults. This needs to be resolved before the drive can function reliably.

Common Causes

  • An option card (e.g., I/O card, communication card) was added or removed without updating the drive's configuration.
  • The installed option card is incompatible with the drive's firmware version or model.
  • Corruption of the drive's internal configuration memory due to power fluctuations.
  • Incorrect parameter settings for newly installed hardware components (e.g., P3-01 for I/O expansion).

Repair Steps & Checklist

Click steps to track your progress.

  1. 1

    1. Power cycle the drive after ensuring all option cards are securely seated in their slots.

  2. 2

    2. Access the drive's diagnostic menu to identify detected option cards and compare with expected configuration.

  3. 3

    3. Perform an 'auto-detection' or 'hardware scan' function (if available via P3-01 or similar parameter) to re-identify installed hardware.

  4. 4

    4. If a backup configuration exists, attempt to restore a known good configuration file via the drive's HMI or service port.

  5. 5

    5. Verify compatibility of all installed option cards with the drive model and current firmware revision.
