SINUMERIK 840D sl/SINAMICS S120 SINUMERIK Safety Integrated (FBSI sl) – 03.2006 Edition
$MN_SAFE_ALARM_SUPPRESS_LEVEL
"Safety Integrated" alarm suppression
Min. input limit: 0
Protection level: 7/2
The monitoring channels NCK and drive display alarms with the same significance in
several situations.
In order to reduce the size of the alarm screen, this MD is used to specify whether safety
alarms with the same significance are to be suppressed. The two-channel stop response is
not influenced by the setting.
0 = alarms triggered in two channels are displayed to the full extent
– Two-channel display of all axial safety alarms
– Alarm 27001, fault code 0 is displayed
– Alarms 27090, 27091, 27092, 27093 and 27095 are displayed through two channels and
a multiple number of times.
1 = alarms with the same meaning are only displayed once.
This involves the following alarms and messages:
27010 = C01707
27011 = C01714
27012 = C01715
27013 = C01706
27020 = C01710
27021 = C01709
27022 = C01708
27023 = C01701
27024 = C01700
For these alarms, only one of the specified alarms (270xx or C01xxx) is initiated. The alarm
of the monitoring channel that then subsequently initiates the alarm with the same
significance, is no longer displayed.
Furthermore, Alarm 27001 with fault code 0 is suppressed. This alarm occurs as a result of
drive Alarm F01711. In this particular case, drive machine data r9710[0], r9710[1], r9711[0],
r9711[1] provide information regarding the cause of the error.
2 = default setting
Going beyond the functionality with MD value=1, the alarms from the SPL processing
(27090, 27091, 27092, 27093 and 27095) are only displayed
through one channel and only once. This also applies to alarms of the PROFIsafe
communications (27250 and following).
3 = axial Alarms 27000 and A01797 are replaced by Alarm message 27100 for all
axes/drives. Alarm 27040 is replaced by Alarm 27140 for all axes/drives.
12 = going beyond the functionality with MD value = 2, the alarms are assigned priorities.
What appears to be apparent follow-on alarms are no longer displayed or are automatically
cleared from the display.
The following alarms may be involved:
27001, 27004, 27020, 27021, 27022, 27023, 27024, 27091, 27101, 27102, 27103, 27104,
27105, 27106, 27107
13 = going beyond the functionality with MD value = 3, the alarms are assigned priorities
as for MD value 12.
This machine data must be set to 0 to generate an acceptance report. This allows the
system to document all of the alarms that have been initiated.
