Acknowledge the alarm using the alarm acknowledgement key or softkey on the HMI.

Verify that the machine data changes you made are functioning as intended by checking affected axes or functions.

Document the MD changes in your machine logbook with date, changed parameters, and reason for modification.

Create a backup of the current machine data using the commissioning archive function to preserve the new configuration.

Always maintain multiple backup versions before making further MD modifications.

Check the alarm log timestamp to confirm this occurred immediately after a power-up or NCK reset sequence.

Review the startup protocols or service notes to identify which MD changes were pending activation.

Perform a reference point approach and test basic machine functions to confirm stable operation with new MD settings.

Do not proceed with production until all safety functions and axis behaviors are verified.

Acknowledge the alarm and clear it from the active alarm display.

Verify the alarm timestamp correlates with recent software update, archive restore, or commissioning activities.

Compare current active MD values against your documented baseline configuration using the MD compare function.

Mismatched MDs after restore operations can cause unexpected machine behavior or collisions.

Run a complete machine function test including all axes, spindles, tool changer, and safety circuits.

Acknowledge alarm and document the system update event with MD activation confirmation in service records.
