6.9 Commissioning TM54F by means of STARTER/SCOUT
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 forced dormant error detection (test
stop) is to be performed. After this interval has elapsed, the user is informed by the
message A35014 that forced dormant error detection (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, forced dormant error detection (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) is displayed. The values of
the F-DIs are frozen for the duration of forced dormant error detection (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.
Feedback F-DO must only be used for f orced dormant error detection (test stop)
With the sequence, unwanted responses of the drive can be caused if the F-DO is not only
used for feedback with forced dormant error detection (test stop) but also for other
purposes.
• Note that the F-DO for feedback with forced dormant error detection (test stop) must not
F-DOs that are not registered for evaluation by means of p10046 are set to "0" for the
duration of the test ("fail-safe values").
Forced dormant error detection (test s top): Duration
The maximum time period for the test is: T
● Test of the FDIs: T
(X = 20 ms or r10015 or p10017 - the longest time of the 3 values determines the waiting
time X)
● Test of the FDOs: T
(Y = p10001 or r10015 or p10017 - the longest time of the 3 values determines the wait
time Y)
The safety functions of the TM54F are executed in the sampling time displayed in r10015.
This sampling time corresponds to the lowest value of the communication sampling time
entered in p10000[0..5].
