Configurable stop The stop responses that occur when the limit values are violated can be
responses selected by the machine manufacturer using the appropriate machine data.
These limit values are defined using the corresponding machine data.

responses
Stop response If a stop response is initiated in the drive, a signal is sent to the NC that
sequence responds by initiating the same stop response (two-channel safety). Likewise, if
a stop response is initiated in the NC, the drive is automatically signaled and
responds by requesting the same stop response (exception: Test stop).
This mechanism ensures that stop responses are managed with a high degree
of safety.

Configurable stop responses
Safety-related functions Configurable stop responses
SBH STOP B* (not configurable)
SG STOP A, B, C, D, E
SE STOP C, D, E
SN No internal stop response.
The user must appropriately configure safe responses via
the SGAs SN1 - SN4.
SBR STOP A (not configurable)
Note:
Stop response STOP F is the predefined system response to discrepancies detected by
the crosswise data comparison.

Note
A stop response listed in Table 3-6 "Stop response priorities" can only be
initiated if at least one safety-relevant function is active (except for STOP F).
Once a stop response has occurred, the sequence of operations it involves
will be completed, even if the cause of the stop no longer exists.
It is possible to progress to stop responses that have a higher priority. It is not
possible to progress to stop responses that have a lower priority.
Please refer to Chapter 3.1.2, "Shutdown paths" for an explanation of how to
use the SGE test stop selection.
