Ex ecution
When parameterizing, proceed as follows:
1. Derive the suitable mode from the circuit used in your application (see figures in the
following chapters).
2. Set the mode that you wish to use in parameter p10047.
3. Use parameter p10046 to define whether the digital output F-DO 0 is to be tested.
4. Use parameter p10001 to set the time within which the digital output signals to the
corresponding digital inputs or DIAG inputs must be recognized.
5. With parameter p10003, set the interval within which forced dormant error detection (test
stop) will be performed. After this interval has elapsed, the user is informed by the
message A01774 that forced dormant error detection (test stop) must be performed for
the F-DI/F-DO.
6. Set the signal source which triggers the start using parameter p10007. This can be, for
example, a control signal or switch via a BICO switchable signal.
While being executed, message A01772 (test stop fail-safe output active) is displayed. The
messages A01772 and A01774 only disappear again after the execution. If an error has
been detected by forced dormant error detection (test stop), fault F01773 is output. Using the
test sequence specified for each mode, you can see which error has occurred from the fault
value of the test step.
Danger to life due t o unwanted movement given improper use of the f eedback DI of t he F-
DO
With the test sequence, unwanted movements of the drive can be caused if the DI of the F-
DO is not only used for feedback with test stop/forced dormant error detection but also for
other purposes.
• Only use the DI of the F-DO for feedback with forced dormant error detection (test stop)
