2. PROFIsafe monitoring time F_WD_Time: 10-65535
A valid current safety telegram must be received from the F-CPU within the monitoring time.
The drive will otherwise switch to the safe state.
The monitoring time should be of sufficient length to ensure not only that the communication
functions tolerate telegram delays, but also that the fault response is triggered quickly
enough if a fault occurs (e.g. interruption of the communication connection).
For additional information on F parameters, refer to the online help of the ("Help subjects"
button).
