Response time after PROFIsafe communication interruption
The inverter receives the PROFIsafe monitoring time from the higher-level-level, fail-safe
control (F-CPU).
If the PROFIsafe telegram is not received before the end of the PROFIsafe monitoring time,
the inverter activates the STO function.
Depending when the interruption takes place, the inverter can signal the following faults:
● Basic functions have been enabled: Fault F01611
● Extended functions have been enabled: Message C01711
