INFORMATION
If the safe digital output is assigned to a drive safety function via the function assign-
ment, this drive safety function is selected in the case of a system error.
Critical fault
In the case of a critical error, the safety option is set to the safe state. The F-DO_STO
is switched to the safe state. In addition, the drive safety function STO is executed
without delay. Active safe communication is suspended.
In addition, the corresponding error code is transferred for the critical error that oc-
curred.
Fault messages
If there is a fault in the safety option, the basic device indicates that the safety option
is reporting a fault.
Measures for fault resolution and more information on causes can be found using the
fault status of the safety option.
