Acknowledgement via PROFIsafe
The higher-level controller sets the signal "Internal Event ACK" via the PROFIsafe telegram
(STW bit 7) separately for each drive object. A falling edge in this signal sets the status
"Internal Event" in the relevant drive, which acknowledges the fault.
Faults in the drive objects (DOs) cannot be acknowledged by the higher-level controller in
the line-up but must instead be acknowledged separately for each individual drive object.
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.
