Siemens · SINAMICS G120C Variable Speed Drive
This fault occurs when a macro cannot be executed due to various configuration or data errors. The fault value (r0949, hexadecimal) provides detailed supplementary information, indicating issues such as an invalid file for the trigger parameter, incorrect data types within the macro (e.g., index, number, or bit not U16), undefined error levels or modes, or attempts to write to parameters that are read-only or not available via macro. Such issues prevent automated configuration or specific functions from running.
Click steps to track your progress.
Record the fault value r0949 (hexadecimal) for detailed supplementary information regarding the macro error.
Select a standard, known-good macro (e.g., P0015=0 for no macro, P0015=1 for standard I/O macro) and attempt execution.
Verify the drive firmware version is compatible with the intended macro set by checking the drive manual or release notes.
Reset drive to factory defaults (P0010=30, P0970=1) and then re-attempt macro selection and application.
If available, use diagnostic tools to check for sufficient internal memory resources for macro execution.
