Effects when the limit value is exceeded for SG

Configurable stop response
When the selected speed limit value is violated, a stop response configured in the
following machine data/parameters is generated:
for 840D sl:
MD 36961: $MA_SAFE_VELO_STOP_MODE
MD 36963: $MA_SAFE_VELO_STOP_REACTION[n]
for SINAMICS S120:
p9561: SI motion SG stop response
p9563[0...3]: SI motion SG-specific stop response
Note
S An alarm is displayed (for 840D sl: 27011, for SINAMICS S120: F01714). After
the cause of the fault has been removed, the alarm can be acknowledged with
RESET. The monitoring function is then again active.
S Depending on the selected monitoring clock cycle, the dynamic drives may
cause a brief increase in speed on the monitored axis/spindle before the stop
response sequence starts.
S For traversing modes which use a transformation with singularity points (e.g.
5-axis transformation and TRANSMIT), relatively high axial speeds occur at
these points. These speeds can initiate stop responses even though the
Cartesian motion of the tool center point (TCP) is below the selected speed
limit value.
The monitoring functions provided by SI are basically axis-specific. This means
that it is not possible to directly monitor the TCP.
