Meaning:
322
$MN_SAFE_ALARM_SUPPRESS_LEVEL
Influences the display of safety alarms.
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 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 significance,
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 communi‐
cations (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_SYNACT_LOCK[0,1]
= 0) by alarm 27135 for all axes.
