Overview of the F-DOs

Description
Failsafe 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 DI
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 (for additional information on forced dormant error
detection, refer to the corresponding function description in the "Extended Functions"
chapter).

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 (p10043) each one of the four drive
groups with the F-DO:
● Power removed (STO active)
● SS1 active
● SS2 active
● SOS active
● SLS active
