5.4 NCK acceptance test support
5.4.2 Internal mechanisms to support the test procedure
In order to support the execution of the individual test steps, defined states are
activated as a result of the interaction between the SinuCom NC operator
interface and NCK/drive. This creates the appropriate requirements relating to
the secondary conditions of the test step, that up until now, had to be manually
set.
If the acceptance test function is selected on the SinuCom NC operator
Acceptance test phase
interface, then on the NCK side, the acceptance test phase is selected. As a
result, the acceptance test phase is continually active while working through the
test list.
In order to ensure that all of the SI alarms are output when they occur while
executing the test steps and that these SI alarms can also be logged, then the
alarm suppression that might have been set in MD 10094
$MN_SAFE_ALARM_SUPPRESS_LEVEL is not taken into account and
therefore does not have to be manually reset to 0 for the duration of the
acceptance test.
The acceptance test phase is de-selected by exiting the acceptance test
function.
Acceptance test mode For the new acceptance test support provided by the NCK and drive, the
SI functions to be tested are sub-divided into groups that require a specific
acceptance test mode (acceptance test from group 1, e.g. SBH test, SG test)
and in groups that do not require an acceptance test mode (acceptance tests
from group 2, e.g. acceptance test for SE).
Acceptance tests with For the test steps of group 1 – these include testing the SBH response and
the acceptance test SG response – an additional state is active under defined secondary
mode conditions. This state has specific internal features that support the test
procedure.
This acceptance test mode becomes active under the following secondary
conditions (in a test associated with group 1):
•
•
•
•
•
For the active acceptance test mode (group 1) the following features are active
for the axis to tested:
•
•

There is no active SI power on alarm for the axis to be tested.
The pulses of the axis to be tested are enabled.
JOG is active as NC mode
The SI monitoring function selected when carrying-out the test step is
active, i.e. if for example the SG2 test is selected as test, then if the SG1 is
active, the acceptance test mode (group 1) is not active.
Both monitoring channels (NCK, drive) allow modes to be activated. The
state that is assumed is subject to a crosswise data comparison between
the NCK and drive.
NCK (Alarm No. 27007) and drive (Alarm No. 300952) return the state
using the "Acceptance test mode active" alarm.
The reference (setpoint) speed limit is de-activated via the axial MD 36933
$MA_ SAFE_DES_VELO_LIMIT. This means that the machine data is
internally handled as if it has been parameterized with 0%. This allows the
axis to be traversed in spite of the fact that the SBH monitoring is active or
