Function of the F-DO

Description
Fail-safe digital outputs (F-DO) consist of two digital outputs plus one digital input that
checks the switching state for forced dormant error detection. The first digital input switches
24 V DC, and the second switches M of the X514 voltage supply.
The status of each F-DO can be read at parameter r10052. The status of the associated DIs
can be read at parameter r10053 for the drive objects of the slave (TM54F_SL).
In order to enable forced dormant error detection, connect the corresponding digital input for
the forced feedback signals of the relays (more information on forced dormant error
detection is provided in the chapter "Safety Integrated Extended Functions").
In the SINAMICS Parameter Manual, function diagram 2853 provides an overview of the fail-
safe outputs F-DO 0...3, and the associated checking inputs F-DI 20...23.
F-DO signal sources
A drive group contains several drives with similar characteristics. The groups are
parameterized at the p10010 and p10011 parameters.
The following signals are available for interconnecting (p10042, ..., p10045) each one of the
four drive groups with the F-DO:
● STO active (power removed)
● SS1 active
● SS2 active
● SOS active
● SLS active
● SLS level
● SSM feedback active
● SOS selected
● Internal event (no active safety fault)
● Safe state
