Cause : MLFB is missing comes when drive detected a mismatch between the MLFB code stored internally and the actual hardware configuration. This is set if the MLFB = 0 after exiting INITIALIZATION (0.0 kW). MLFB = order number.

F060 fault in siemens master drive indicate the Machine List (MLFB) data issue. The MLFB is a unique identifier code assigned to each specific Siemens drive model. It encodes information about the drive's power rating, voltage class, and other key specifications.

1. After acknowledgement, in INITIALIZATION enter a suitable MLFB in parameter P070 MLFB (6SE70..).
2. Only possible with the corresponding access stages to both access parameters.
3. Enter correct MLFB after acknowledging the fault (power section, initial loading)
