Parameters:

Definitions:
No stop reaction is initiated. The message will be present during enabling of the functions SN/SE until the axis status “Axis safely referenced” has been reached. Request: In monitoring cycle.
1) The axis is not referenced or
2) The user enable for this axis is missing or was canceled. This can occur, for example, if the axis was moved after the machine was switched off and the standstill position which was stored is therefore no longer correct. This message prompts the user to confirm the actual position. To do this, you must determine the position, e.g. as follows: • Measure the position. • Move to a known position.
Reactions:
– Alarm display.
Remedy:
Please inform the authorized personnel/service department. If no safe automatic referencing is possible, the user must confirm the new position via the soft key. This user con- firmation marks this position as safe, that means the axis status “Axis safely referenced” is reached. Warning: If the axis has not been safely referenced and the user has not confirmed, the following applies: • The safe cams are still active and not yet safe. • The safe limit positions are not yet active.
