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
Function 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 ca
se.
