4. Use parameter p10041 to define which failsafe digital inputs are to be checked during the
test.
Inputs which do not have L1+ and L2+ power supplies may not be selected for the test.
It is only possible to test the sensors connected to the F-DIs, if these are supplied from
L1+ or L2+. If F-DOs of preprocessing devices are connected, forced checking procedure
(test stop) cannot be used for this input.
5. Use parameter p10001 to set the time within which the digital output signals to the
corresponding digital inputs DI 20 ... DI 23 or DIAG inputs must be recognized. Select this
time depending on the maximum response time of the external F-DO circuit.
6. With parameter p10003, set the interval within which the forced checking procedure (test
stop) is to be performed. After this interval has elapsed, the user is informed by message
A35014 that the forced checking procedure (test stop) must be performed for the TM54F.
7. 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.
Alternatively, the forced checking procedure (test stop) can be performed automatically
every time the power supply is switched on (POWER ON) (p9507.6 = 1).
During execution, message A35012 (TM54F: Test stop active). The values of the F-DIs are
frozen for the duration of the forced checking procedure (test stop). The messages A35014
and A35012 only disappear again after the execution. If an error is found during the test,
fault F35013 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.
F-DO that are fed back must only be used for the forced checking procedure (test stop)
With the sequence, unwanted responses of the drive can be caused if the F-DO is not only
used for feedback with the forced checking procedure (test stop) - but also for other
purposes.
• Note that the F-DO for feedback signals for the forced checking procedure (test stop)
F-DOs that are not registered for evaluation by means of p10046 are set to "0" for the
duration of the test ("failsafe values").
