Configuring the fault, message and alarm buffer
7.8.1
General information on the fault buffer and safety message buffer
In addition to the standard fault buffer and the standard alarm buffer, a SINAMICS S120 drive
has its own safety message buffer for safety-related messages for Safety Integrated Extended
Functions:
●

7.8.2
Configuring the standard alarm buffer
The standard alarm buffer is automatically activated when you configure the safety mode.
This alarm buffer is required for safety-related standard warnings (Axxxx).
The display of safety-related standard warnings cannot be activated independently of the
display of other standard warnings.

Commissioning Manual, 02/2020, A5E46305916B AB
Messages for Extended Functions are displayed in the safety message buffer.
● You must enable SIC/SCC for the appropriate axes in MD39750.
● To acknowledge messages in the safety message buffer, safety-relevant acknowl‐
edgment is required - and possibly also acknowledgment with PROFIdrive RESET
(Page 338).
Messages for Basic Functions or for external drives without an NC axis assignment,
cannot be saved to the safety message buffer.
● When using external drives without NC axis assignment, then you must deactivate the
safety message buffer (Page 336).
● The response when saving safety-relevant messages relating to Basic Functions cor‐
responds to the response for a deactivated safety message buffer (see below).
If the safety message buffer is deactivated, then safety-relevant messages are saved in
the standard fault and/or alarm buffer.
● For safety-related messages in the fault and alarm buffer, in the SINUMERIK ONE
Commissioning Tool, specific reference is not made to the safety-relevant acknowl‐
edgment required.
Safety-relevant alarms are displayed in the SINUMERIK ONE Commissioning Tool in
the standard alarm list ("MENU SELECT > Diagnostics > Alarms"); however, they
require safety-relevant acknowledgment.
● The messages require additional acknowledgment: For an entry in the fault buffer, in
addition alarm 25201 ("Drive fault") is output, and the drive message requires a safety-
relevant acknowledgment as well as also an acknowledgment via PROFIdrive
(Page 339).
