The embedded fieldbus (EFB) configuration file could not be read by the drive. This prevents the EFB protocol from initializing correctly. The fieldbus communication will not function, and the drive cannot be controlled via EFB.
Click steps to track your progress.
Attempt to re-upload the correct EFB configuration file from the PC configuration software (e.g., DriveWorks, Drive Composer) to the drive.
Verify that the EFB protocol selected in parameter P7-00 (EFB Protocol) is correct and matches the fieldbus system in use.
Check the drive's firmware version (P0-01 Firmware Version) against the EFB module documentation for compatibility requirements. Update firmware if necessary.
Perform a drive parameter reset to factory defaults (e.g., P9-02) and then manually reconfigure only the essential EFB parameters.
If using a removable memory card for configuration storage, ensure it is properly inserted and not corrupted. Try a different memory card if available.
