Alarm 101202

Siemens 840D 101202 - Copying SI data from axis to drive

Alarm 101202 is an informational message that fires during the SI (Safety Integrated) data copying process from axis parameters to the corresponding drive unit. This is a normal operational alert indicating active SI parameter synchronization between NCK axis definitions and DRIVE-CLiQ drive objects, not a fault condition.

Causes and Fixes

1
Verify SI data copy completion by monitoring Diagnostics > Drive > SI Data Status. The alarm should clear automatically once the copy operation completes (typically within 2-5 seconds).
2
Check DRIVE-CLiQ communication status in HMI: Diagnostics > Axis > Communication > DRIVE-CLiQ link quality should show >95% availability during SI copy.
If link quality drops below 80%, interrupt the process and check cable connections.
3
Confirm SI activation is enabled by reviewing MD10700 (SafetyIntegrated Activation) and MD10750 (SI Monitoring Level) on the affected axis in NCK > Axis Parameters menu.
4
Allow the system to complete automatic SI data download. Do not interrupt power or communication during this process, as incomplete SI data transfer may cause subsequent safety function failures.
Forced interruption of SI copy can corrupt safety parameter integrity on the drive.
