Figure 5-15 Filter to suppress brief signals
The filter extends the response time of the safety function by the debounce time.
Parameter
Description
p9650
F-DI switchover discrepancy time (Factory setting: 500 ms)
Tolerance time to change over the fail-safe digital input for the basic functions.
p9651
STO debounce time (factory setting: 1 ms)
Debounce time of the fail-safe digital input for the basic functions.
p10002
F-DI switchover discrepancy time (Factory setting: 500 ms)
Tolerance time to change over the fail-safe digital inputs for the extended functions.
p10017
Digital inputs debounce time (factory setting: 1 ms)
Debounce time of the fail-safe digital inputs for the extended functions.
Debounce times for standard and safety functions
The debounce time p0724 for "standard" digital inputs has no influence on the fail-safe digital
input F-DI signals. Conversely, the same applies: The debounce time of the fail-safe digital
inputs 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 digital input, set the debounce time as described above.
