Notes on project planning for "SOS"
When using the safety function "Safe operating stop", it is absolutely necessary
to comply with the following safety instructions:
R911404905, Edition 02
Safety functions in special mode "Safe standstill"
Direct selection: The safety function can be directly selected via the active
"SafeMotion" profile (P‑0‑3264).
NOTE: Before the safety function is directly selected, the drive system has to
be decelerated via the command value input; drive-controlled deceleration is
not carried out!
Indirect selection: The safety function is automatically activated at the end
of the transition function "Safe stop 2 (SS2)".
The function "Safe operating stop is deselected by selecting the safety func-
tion "Safe torque off (STO)" or by deselecting the safety function.
After terminating the safe operating stop, e.g. by deselecting the safety func-
tion and executing the start command, the working motion of the drive can
be immediately continued at the point of interruption.

⇒ If external force influences are to be expected with
the safety function "Safe operating stop", e.g. in case of
a vertical axis, this motion must be safely prevented by
additional measures, e.g. a mechanical brake or counter-
weight. For such axes, Bosch Rexroth recommends using
the Safe braking and holding system.
