9.4 Changing data

Warning
!
From SINAMICS SW2.5 onwards, the following applies:
In a system configuration, the firmware versions of the DRIVE–CLiQ components
can only differ from the versions on the CF card, if either
a) the automatic upgrade/downgrade (parameter p7826) is deactivated, or
b) components with a new firmware version can no longer be downgraded to the
status of the version available on the CF card.
Scenario a) is not permitted when Safety Integrated is used. The automatic
upgrade/downgrade must not be disabled when Safety Integrated is used.
(automatic firmware update (p7826) must be equal to 1)
Scenario b) is only permissible if this combination has been explicitly approved by
the manufacturer.
9.4 Changing data
The user must enter the correct password before he can change the machine data
for SI functions to the system. After data for SI functions has been altered, a new
acceptance test must be carried out on the SI function(s) involved and then re-
corded and confirmed in the acceptance report.
Change report
Changes made to NCK machine data important for Safety Integrated are recorded
in a display data. The times that these changes were made are displayed in axial
MD 36996: $MA_SAFE_CONFIG_CHANGE_DATE[0...4].
This MD can neither be overwritten by manual entry nor by loading an MD archive.
It can only be deleted by booting the control from the general reset mode (switch
position 1).
This data is updated when the following changes are made to the NCK machine
data:
S When a modified safety MD configuration is activated
(NCK safety MD have been changed and acknowledged by correction of
$MA_SAFE_DES_CHECKSUM).
S When MD $MA_SAFE_FUNCTION_ENABLE is changed from values not equal
to zero to zero, or from zero to values not equal to zero. These changes mean
that the safety functionality of an axis is completely enabled/disabled. Other
changes to MD $MA_SAFE_FUNCTION_ENABLE always change MD
$MA_SAFE_ACT_CHECKSUM, which themselves have to be acknowledged
by changes to MD $MA_SAFE_DES_CHECKSUM.
