The activation is entered in the following machine data:
● MD13150 $MN_SINAMICS_ALARM_MASK
– "bit 2: output faults of the drive controls"
– "bit 10: output alarms of the drive controls"
Alarms/warnings have to be evaluated.
Optionally, you can set additional bits in order to output faults or alarms of other DO groups.
7.8.3 Configuring the safety alarm buffer
The safety message buffer is activated in the factory setting, and is used for safety-related
messages from Extended Functions.
Under certain circumstances it can also make sense to deactivate the safety message buffer
for Extended Functions so that the messages of Basic Functions as well as those of Extended
Functions are saved to the fault and/or alarm buffer (for example, if you are predominantly using
Basic Functions).
The setting to activate/deactivate the safety message buffer is a CU parameter (p3117). It
cannot be set on a drive-specific or axes-specific basis, but is always applicable for all drives
and/or axes of this CU.
The following drive parameter is relevant:
● p3117 change safety message type/ Ch. SI mess type
Setting to re-parameterize all safety messages to faults and alarms.
Precondition
● Settings for drive parameters are protected with access level 2 (service).
Procedure
Proceed as follows to deactivate or activate the safety message buffer:
1. In the SINUMERIK ONE Commissioning Tool, call the drive parameters via "MENU
SELECT > Commissioning > Machine data > Control Unit parameters".
2. Activate the CU commissioning state "Device configuration" with "p9=1".
3. Set the required value in drive parameter p3117 Change safety message type / Ch. SI mess
type:
– p3117=0: Safety messages of this CU are not reparameterized; this means that
messages associated with Extended Functions are entered in the safety message buffer.
– p3117=1: All safety messages of this CU are reparameterized, and entered in the
standard fault or alarm buffer.
4. Deactivate the CU commissioning state "Device configuration" with "p9=0".
5. Confirm the setting with "Save/reset> Menu forward key> Reset (po)".
