EFB invalid parameterization
ABB · ACS880
What does 6683 mean?
The embedded fieldbus (EFB) parameter settings are inconsistent or not compatible with the selected protocol. This prevents the EFB from operating correctly, leading to communication failure. Reviewing and correcting parameter settings is crucial.
Common Causes
- Inconsistent or incompatible parameter settings within the EFB group (P7-xx) for the selected fieldbus protocol (e.g., P7-00 EFB Protocol set to Modbus, but EtherNet/IP parameters are configured).
- Required process data mapping (e.g., P7-10 to P7-19 for input/output data) is either missing, incomplete, or incorrectly defined for the chosen EFB profile.
- A combination of EFB parameters is not supported by the drive's firmware or the specific EFB module installed.
- Mismatch between the drive's EFB configuration and the settings on the fieldbus master (e.g., master expects 32-bit words, drive sends 16-bit).
- Incorrect network topology settings (e.g., for PROFINET, Device Name or IP settings not matching expected format).
Repair Steps & Checklist
Click steps to track your progress.
- 1
Review all fieldbus-related parameters, particularly the P7-xx group, to ensure consistency and correctness for the selected EFB protocol (P7-00).
- 2
Verify that the process data mapping parameters (e.g., P7-10 to P7-19 for input/output words) are correctly configured and enabled as required by the EFB protocol.
- 3
Cross-reference the drive's EFB parameter settings with the fieldbus master's configuration software to identify any discrepancies in addresses, data types, or communication profiles.
- 4
Perform a partial parameter reset specifically for the EFB group (e.g., use P9-02 to reset only group 7) and then re-enter the parameters from scratch.
- 5
Consult the drive's detailed fieldbus manual for the specific parameter requirements and limitations of the chosen EFB protocol (e.g., EtherNet/IP, PROFINET, Modbus RTU).
