Siemens alarm 380500: PROFIBUS/PROFINET: fault on drive (fault code + fault value shown)
SINUMERIK 828D drive fault presentation (SINAMICS via PPU) · Siemens 828D
What it means
Carrier alarm presenting the connected SINAMICS drive object's own fault number and value on the 828D/840D screen; look the embedded code up in the SINAMICS list manual (F30001/F30004/F30005/F30027 etc.).
Likely causes
- any underlying SINAMICS power/encoder/communication fault
- stale topology after module exchange
- PROFIBUS address/telegram configuration mismatch
Triage note: Record the displayed fault value (usually r2124/r0949 content) - it discriminates e.g. which phase, which temperature, which component slot.
