Safety input
• If you enable safety function STO, then the failsafe digital input comprises the two digital inputs DI 4
and DI5.
• Input voltage ≤30V, 5.5 mA
• Response time:
– When the debounce time p9651 > 0: Typical 5ms + p9651, worst case 15ms + p9651
– When debounce time = 0: Typical 6ms, worst case 16ms
PFH (Probability of
Failure per Hour)
Probability of failure of the safety functions: 5 × 10E-8
USB interface Mini-B
11.2 High Overload and Low Overload
Permissible converter overload
The converter has two di󹪜erent power data: "LowOverload" (LO) and "HighOverload" (HO),
depending on the expected load.
