CFF

Incorrect Configuration

Schneider Electric · Altivar 312 Variable Frequency Drive

What does CFF mean?

This fault indicates that the drive's current configuration is inconsistent or has become corrupted, possibly due to the addition or removal of an option card without proper reconfiguration. An inconsistent configuration can lead to unpredictable drive behavior or prevent it from operating correctly, posing a risk to the application.

Common Causes

  • Option card (e.g., I/O expansion, communication card) added or removed without performing a drive re-initialization.
  • Parameter corruption due to unstable power fluctuations or improper shutdown sequences.
  • Firmware update process was interrupted or failed, leading to an inconsistent or incomplete parameter set.
  • Drive model or rating detected inconsistently with the loaded configuration parameters.
  • Incompatibility between the loaded parameter set and the current drive firmware version.

Repair Steps & Checklist

Click steps to track your progress.

  1. 1

    1. Perform a parameter reset to factory defaults (e.g., set Parameter P1-12 = 1 or 2) and reconfigure essential parameters.

  2. 2

    2. Verify all installed option cards are securely seated in their slots and are compatible with the drive model.

  3. 3

    3. Load a known good configuration file from a previously saved backup via serial communication or USB.

  4. 4

    4. Check the drive's firmware version (typically displayed on the HMI during startup) against application requirements.

  5. 5

    5. Power cycle the drive and verify each installed option card is recognized in the relevant parameter group (e.g., P0-XX for option card status).
