公式トラブルシューティング手順
Message value: %1 Drive object: All objects Reaction: A_INFEED: NONE (OFF2) SERVO: NONE (OFF1, OFF2, OFF3) VECTOR: NONE (OFF1, OFF2, OFF3) Acknowledge: IMMEDIATELY Cause: Writing to at least one parameter back-up file PSxxxyyy.*** on the CompactF lash card was unsuccessful. - on the CompactFlash card in the directory /USER/SINAMICS/DATA/ at least one parameter backup file PSxxxyyy.*** has the "read only" file attribute and cannot be overwritten. - there is not sufficient free memory space on the CompactFlash card. - the CompactFlash card is defective and cannot be written to. Fault value (r0949, interpret hexadecimal): dcba hex a = yyy in the file names PSxxxyyy.*** a = 000 --> consistency back-up file a = 001... 062 --> drive object number a = 099 --> PROFIBUS parameter back-up file b = xxx in the file names PSxxxyyy.*** b = 000 --> data save started with p0977 = 1 b = 010 --> data save started with p0977 = 10 b = 011 --> data save started with p0977 = 11 b = 012 --> data save started with p0977 = 12 d, c: Only for internal Siemens troubleshooting. Remedy: - check the file attribute of the files (PSxxxyyy.***, CAxxxyyy.***, CCxxxyy y.***) and, if required, change from "read only" to "writeable". - check the free memory space on the CompactFlash card. Approx. 40 kbyte of free memory space is required for every drive object in the system. - replace the CompactFlash card.
