Alarm display
A STOP D/E is initiated (this can be set using MD10097
$MN_SPL_STOP_MODE) on all of the axes with safety functionality if
the SPL commissioning phase (MD11500 $MN_PREVENT_SYN-
ACT_LOCK[0,1] not equal to 0) has been completed.
Analyze the displayed value and evaluate DB18: SPL_DELTA on the
PLC side.
Find the difference between the monitoring channels.
Possible causes:
-- Incorrect wiring
-- Incorrect SPL
-- The axis--specific SGEs have been incorrectly assigned to the
internal interface $A_OUTSI
-- The axis--specific SGAs have been incorrectly assigned to the
internal interface $A_INSI
-- The SPL--SGEs have been incorrectly assigned to the external
interface $A_INSE
-- The SPL--SGAs have been incorrectly assigned to the external
interface $A_OUTSE
-- Different SPL commissioning status has been set in the NCK and
PLC
-- Different SPL stop response has been set in the NCK and PLC
Clear the alarm with the RESET key. Restart the part program.
Error for crosswise data comparison, NCK- -PLC, STOP of %1
%1 = supplementary information about the monitoring channel that has
initiated the stop
The monitoring channel specified in %1 (NCK or PLC) has initiated a
STOP D or E (depending on the parameterization in MD10097
$MN_SAFE_SPL_STOP_MODE). Alarm 27090 provides additional
information about the reason for the Stop D/E.

Evaluate the alarm parameters of Alarm 27090 and correct the SPL, or
check the internal SPL interfaces to the safety monitoring channels in
the NCK and drive.
Clear the alarm with the RESET key. Restart the part program.
