With OUT3=0 the drive is brought to standstill with fast stop.
The subsequent safe shutdown becomes active with a time
delay (see figure below). Without time delay, the pulse blocking
(Option K80) would be active immediately so that a fast
stop (with OUT3) would not be possible any more.
NERR_ESTP_FDOR receives the state of the SR flip-flop from
NW1, which sets or resets OUT3. If OUT3 is reset, DELAY_80 is
also reset after the time parameterized at PT has elapsed.

FB F_FDBACK (FB216) is a certified block from the Distributed
Safety block library.

Further information on the FB216 is available for example
by selecting it in the block editor and pressing
F1.

FC "REINT" (FC 10)
The FC 10 causes the reintegration of F-DI and F-DO, in order
to depassivate them. This requires that:
■ the error that caused the passivation has been removed
and
■ a positive edge has been set at the parameter ACK_REI of
the respective F-Periphery DB.
A passivation is indicated by an illuminated LED "SF" on the
module. The reintegration of an F module may take several
minutes.
