Specification
Fail-safe input
•
DI 4 and DI 5 form the fail-safe digital input.
•
Maximum input voltage 30 V, 5.5 mA
•
Response time:
–
Typical: 5 ms + debounce time p9651
–
Typical, if debounce time = 0: 6 ms
–
Worst-case scenario: 15 ms + debounce time
–
Worst case, if debounce time = 0: 16 ms
•
You will find the extended function data in the Safety Integrated Func-
tion Manual.

Note
Short-term voltage dips in the external 24 V supply (
≤ 3
ms and ≤
95% of the rated voltage)
When the mains voltage of the inverter is switched off, the inverter responds to short-term
voltage dips in the external 24 V supply with fault F30074. Communication via fieldbus,
however, remains in effect in this case.
