MD number
$MN_SAFE_ALARM_SUPPRESS_LEVEL
"Safety Integrated" alarm suppression level
840D
Default: 2 Min. input value: 0 Max. input value: 13
Change becomes effective after POWER ON: Protection level (R/W) 7/2 Unit: -
Data type: BYTE Applies from SW 6
Meaning The monitoring channels NCK and 611 digital display alarms with the same significance in
several situations.
In order to reduce the size of the alarm image, 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 this setting.
0 = Alarms triggered in two channels are displayed to the full extent
- Two-channel display of all axial safety alarms
- Alarm 27001, error code 0 is displayed
- The Alarms 27090, 27091, 27092, 27093 and 27095 are displayed a
multiple number of times using 2 channels
1 = Alarms with the same meaning are only displayed once.
The following alarms are affected:
27010 = 300907
27011 = 300914
27012 = 300915
27013 = 300906
27020 = 300910
27021 = 300909
27022 = 300908
27023 = 300901
27024 = 300900
With these alarms, only one of the specified Alarms (270xx or 300xxx) 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 error code 0 is suppressed. This alarm occurs
as a result of drive Alarm 300911. In this particular case, drive machine data
1391, 1392, 193, 1394 provide information regarding the cause of the error.
2 = Default
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 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.
3 = Axial Alarms 27000 and 300950 are replaced by Alarm message 27100 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 affected:
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.
