The parameter settings for the embedded fieldbus (EFB) are inconsistent or incompatible with the selected protocol. This prevents the EFB from establishing a stable connection or communicating effectively, leading to operational errors.
Click steps to track your progress.
Access drive parameters via control panel or PC tool (e.g., Drive Composer) and verify EFB protocol selection in P7-01.
Compare EFB node address (P7-02) and baud rate (P7-03) settings with the fieldbus master's configuration, adjusting as needed.
Review I/O data mapping parameters (P7-20 to P7-29) to ensure consistency with the fieldbus master's Process Data Object (PDO) setup.
Perform a parameter reset to factory defaults (P96-01=1) and re-enter all EFB-related parameters according to the fieldbus master's GSD/GSDML file.
If a firmware update occurred, reload the correct GSD/GSDML file into the fieldbus master and re-configure the EFB instance.
