Causes and Fixes

1
Note the exact error code shown in %2 parameter and document the active program and operation mode when alarm occurred.
2
Perform NCK RESET by pressing RECALL key, then attempt to clear the alarm. If alarm persists, perform a complete controller restart (power cycle).
Save all active programs and work offsets before power cycling the control.
3
Check NCK memory utilization in Diagnostics > NCK > Memory. If usage exceeds 85%, delete unused programs or expand memory.
4
If alarm recurs, boot from the Siemens commissioning/service boot stick and perform an NCK data backup, then restore factory defaults and reload machine data.
This will erase all NC programs and offsets. Ensure complete backup exists before proceeding.
