System function and position

Rebuilt from individual evidence

Unknown: evidence boundary

The cited Transnet Ports Terminals repair scope lists 6SE7027-2TD84-1HF5 as a firing card.

The cited scope places this firing card in a VFD repair and requires load testing after the repaired drive is completed.

At system level, the part controls the firing-card stage inside the identified VFD repair path; this placement is an explicit inference from the cited facts.

Unknown: the individual unit's condition, revision, wiring, drive configuration, and current commercial status.
