$MA_SAFE_CONFIG_CHANGE_DATE[0...7]
Display data:
Date and time of the last configuration change of safety-related NCK axis machine data.
Changes made to the machine data that are calculated into the axis-specific checksums
MD36998 $MA_SAFE_ACT_CHECKSUM[] are recorded.
$MA_SAFE_PREV_CONFIG[0...8]
Data, previous safety axis configuration
Min. input limit: 0H
Buffer memory to save previous safety configuration data

$MA_SAFE_STANDSTILL_POS
Standstill position
Min. input limit: -
The position at which the axis has currently stopped is displayed in this MD.
To be able to perform a plausibility check on the axis referencing when the control system is
powered-up the next time, the current axis position is permanently saved (in a non-volatile
fashion) when the following events take place:
● When Safe Operating Stop (SBH) is selected
● Cyclically when SE/SN activated
Any manual changes to the MD are detected the next time that the control is powered-up
(plausibility check). A new user agreement is required after referencing.
