Siemens CU240B-2 Function Manual

6. Adjust the wait time. The following lower limits apply for the setting:
– The wait time must be longer than the response time t
R
of the connected actuator.
– The wait time must be longer than or equal to 24 ms.
– The wait time must be longer than the time for the input filter of the feedback input
(p10017).

7. Close the screen forms.
You have defined which signal the inverter transfers via its fail-safe digital output, and how the
inverter tests its fail-safe digital output.
Procedure with Startdrive
To set the fail-safe digital output, proceed as follows:
1. Select "F-DI / F-DO / PROFIsafe".

2. Interconnect the status signals of your choice with the fail-safe digital output. The
"Safestate"signal is described below.
The inverter logically combines the status signals according to the following rules:
– The inverter ignored inputs without interconnection.
– If none of the inputs is interconnected, then the output signal = 0.
3. Activate the test for the fail-safe digital output.
4. Select the test mode that is compatible with your application.
5. Adjust the wait time. The following lower limits apply for the setting:
– The wait time must be longer than the response time t
R
of the connected actuator.
– The wait time must be longer than or equal to 24 ms.
– The wait time must be longer than the time for the input filter of the feedback input
(p10017).
