SINUMERIK 840D sl/SINAMICS S120 SINUMERIK Safety Integrated (FBSI sl) – 03.2006 Edition
10.2 NCK safety alarms for Sinumerik 840D sl
The display of Alarm 27090 can be influenced using the MD
$MN_SAFE_ALARM_SUPPRESS_LEVEL: MD
$MN_SAFE_ALARM_SUPPRESS_LEVEL = 2 : Alarm 27090 is only
displayed for the first data difference found.
Alarm display
A STOP D/E is initiated (this can be set using MD
$MN_SPL_STOP_MODE) on all of the axes with safety functionality if
the SPL commissioning phase (MD
$MN_PREVENT_SYNACT_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 axial SGEs have been incorrectly assigned to the internal
interface $A_OUTSI
– The axial SGAs have been incorrectly assigned to the internal
interface $A_INSI
– 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 in 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 MD
$MN_SAFE_SPL_STOP_MODE). Alarm 27090 provides additional
information about the reason for the Stop D/E.
Alarm display
A STOP D/E is initiated (this can be set using MD
$MN_SPL_STOP_MODE) on all of the axes with safety functionality if
the SPL commissioning phase (MD
$MN_PREVENT_SYNACT_LOCK[0,1] not equal to 0) has been
completed.
Evaluate the alarm parameters of Alarm 27090 and correct the SPL, or
check the I/O modules/wiring or 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.
