Alarm 100015

Siemens 840D 100015 - Error in: file

SIEMENS alarm 100015 indicates a critical error in servo system logging functionality, typically occurring when the SINUMERIK control cannot properly write to or access servo diagnostic log files. This alarm is triggered when the servo system encounters file system errors, corrupted log entries, or insufficient memory allocation for servo data logging operations.

Safety

Refer to Siemens documentation
Ensure qualified technician performs repairs

Causes and Fixes

1
Check servo log file integrity
Navigate to HMI → Diagnostics → Service → Servo Logs and verify if servo log files are accessible and not corrupted.
Look for unusual file sizes or timestamps that don't match recent servo operations.
2
Verify CF card file system
Access SINUMERIK file system via HMI → Startup → CF Card and run file system check to detect and repair corrupted sectors.
Always backup critical data before running file system repairs.
3
Clear and reinitialize servo logs
Delete corrupted servo log files via HMI → Service → Delete Logs and restart NCK to reinitialize servo logging system.
Document any error patterns before clearing logs for future reference.

DIY Feasiblehigh confidence

Call a technician if:

·CF card hardware failure detected
·Multiple drive communication failures
·NCK memory hardware errors
·Repeated alarm after all troubleshooting steps

Prevention

Regular CF card health monitoring
Periodic servo log cleanup
Monitor NCK memory utilization trends
Maintain servo firmware update schedule

Common Mistakes

Ignoring CF card wear indicators
Not backing up logs before clearing
Modifying logging parameters without understanding memory impact
Updating only NCK software without checking drive firmware compatibility
