9.5 Acceptance test
Internal signal trace function
The SinuCom NC internal trace function is started when the data trace is started
and the signals, relevant for the specific test step, recorded. The trace is either
automatically ended or the user ends it for some tests (external stops, Emergency
Stop).
Specific NC machine data must be set in order that the trace function can be used.
This prepares the appropriate resources for the function. The values to be set
should be taken from the SINUMERIK SinuCom NC start–up tool.
Basic operating information and instructions
S The operator is prompted, step–by–step when carrying out a test. The following
limitations/constraints must be observed, especially for those tests that use the
internal trace function:
If a traversing direction has been selected, then this must also be taken into
account for the subsequent task. The reason for this is that the trigger condi-
tion for the automatic data acquisition and evaluation is based on this direc-
tion data
A procedure is initiated to activate the trace function using the button <start
data acquisition>. This can take several seconds. The signal is only acquired
after the appropriate feedback has been received in a message box.
If the trace has to be manually terminated, then this step should, if at all pos-
sible, be made directly after the last expected signal change that is relevant
for the trace. This ensures that the relevant area is optimally displayed in the
subsequent trace display.
S For each test step, the operator must decide as to whether the test was suc-
cessfully carried out. He should make this decision based on traced and deter-
mined data and test situations that have been carried out and documented.
This can be confirmed after the test has been carried out by selecting the ap-
propriate results.
S The test list, provided and supported by SinuCom NC includes the basic test
steps to be carried out. Depending on the machine configuration, several tests
may not be necessary for the particular machine. This can be selected in the
basic screen of the test step. Further, there are test cases, that are required for
the machine but are not (or still not) included within the scope of the test list,
e.g. measuring the braking travel when a light barrier is obstructed, or similar.
These tests should still be manually executed.
S When generating the acceptance certificate, for documentation purposes, data
is automatically retrieved from some machine data (SI limit values, checksums,
hardware information).
Further, the results of the tests that were carried out are incorporated in the
document. The report is structured the same as the document that was pre-
viously manually created. Some sections, such as for example, the machine
overview, function table of the configured safety functions etc., that are not
standardized, are still manually incorporated in the document at a later date.
