Setting The Forced Checking Procedure (Test Stop) - Siemens SINAMICS G120 Operating Instructions Manual

Figure 6-24
A filter in the inverter suppresses brief signals as a result of the bit pattern test or contact
bounce.
Figure 6-25
The filter extends the response time of the safety function by the debounce time.

Debounce times for standard and safety functions
The debounce time p0724 for "standard" digital inputs has no influence on the fail-safe input
signals. Conversely, the same applies: The F-DI debounce time does not affect the signals of
the "standard" inputs.
If you use an input as a standard input, set the debounce time using parameter p0724 .
If you use an input as a fail-safe input, set the debounce time as described above.
