We have three similar machines based on Simotion D425 (6AU1425-0AA00-0AA0), a smart line module, and two motor modules (6SL3120-2TE15-0AA4). All of them share identical hardware and projects. These machines have been running smoothly for years, but one of them unexpectedly stopped one day, triggering multiple alarms on the HMI. The D425 went into stop mode, and the SF LED lit up. The team attempted to resolve the issue by re-downloading the project using Simotion Scout v4.3. Although the download was successful, the SF LED on the D425 remains lit in red. The Run LED is green, but the Ready LED is red, and the Stop LED is also illuminated. These issues seem to be related to Sinamics drives errors. Upon checking the alarms, various technological alarms and drive faults/errors were identified. Notably, there is no issue with the project, as it runs smoothly on the other two machines and has been functioning flawlessly for years, even on the problematic machine. I have attached the diagnostic buffer. Please provide guidance on resolving the drive issues as the manual didn't help much.
