Safety Integrated Functions
8.5 Safety Integrated Extended Functions
Examples for illustrating the information in the table:
1. Safety function SS1 has just been selected. STOP A remains active; a STOP B operation
2. The SLS safety function is selected. This selection does not modify the function of STOP
3. Stop response, STOP C is selected. If the STO or SS1 safety functions are active, this
Acknowledging the safety faults
NOTICE
Safety faults can also be acknowledged (as with all other faults) by switching the drive unit
off and then on again (POWER ON).
If this action has not eliminated the fault cause, the fault is displayed again immediately
after power up.
Acknowledgment via PROFIsafe
The higher-level controller sets the signal "Internal Event ACK" via the PROFIsafe telegram
(STW bit 7). A falling edge in this signal resets the status "Internal Event" and so
acknowledges the fault.
Acknowledgment via F-DI
If the signal "Internal Event ACK" is connected with an F-DI, a falling edge in this signal
resets the status "Internal Event" and so acknowledges the fault. For safety reasons, the
external signal on the F-DI with the "Internal Event ACK" function must not be set
continuously to the "1" level; for acknowledgment, it must first be set from the idle state "0" to
"1" and then back to "0" again.
Extended acknowledgment
If STO is selected/deselected (and p9307.0/p9507.0 = 1 are set), safety messages, in
addition to fault messages, are also canceled automatically.

does not have any effect. If SS2 is active, this braking ramp is retained. If SOS is active,
SOS remains effective, which is also the end status of STOP C. When SLS is selected,
the drive is decelerated with STOP C.
