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.
Click steps to track your progress.
Review all fieldbus-related parameters, particularly the P7-xx group, to ensure consistency and correctness for the selected EFB protocol (P7-00).
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.
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.
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.
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).
