$MN_SAFE_ALARM_SUPPRESS_LEVEL
Alarm suppression level
Min. input limit: 0
Protection level: 7/2
Influences the display of safety alarms.
The monitoring channels NCK and drive or NCK and PLC 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 axis- -specific 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 signifi-
cance, is no longer displayed.
Furthermore, Alarm 27001 with fault code 0 is suppressed. This alarm occurs as a result of
drive Alarm C01711. In this particular case, drive parameters r9710[0,1], r9711[0,1],
r9735[0,1], r9736[0,1], r9737[0,1], r9738[0,1], r9739[0,1] 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 = axis- -specific 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 prioritized. 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.
1xx (100 position set) = axis- -specific checksum alarms of the NCK (27032, 27035, 27060)
are replaced in the SPL commissioning mode (MD11500 $MN_PREVENT_SYN-
ACT_LOCK[0,1] = 0) by alarm 27135 for all axes.
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.
