Switching The System On/Off - Siemens SINUMERIK 840D sl Function Manual

● STOP E
● Extension n<n
Note
● To ensure that SBH can always be selected in the event of an error, the function SBH/SG
must be activated and appropriately parameterized when the function SE and/or SN are
(is) enabled.
● The axis-specific enable data in the NCK must match those in the drive, otherwise, the
crosswise data comparison signals an error.
● An SI axis is treated as an axis in terms of the global option if at least one safety-related
function is activated via the axis-specific enable data.
● The maximum number of axes that may operate with SI and SPL SGE/SGAs is the number
that was enabled using the options.

Switching the system on/off

Firmware version / CF card version
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.
Case a) is not permitted when Safety Integrated is used. The automatic upgrade/downgrade
must never be deactivated when Safety Integrated is used. (automatic firmware update
(p7826) must be equal to 1)
Case b) is only permissible if this combination has been explicitly approved by the
manufacturer.
