5.4 NCK acceptance test support
The following features apply for an active acceptance test (group 2) for the axis
to be tested:
•
•
The acceptance test (group 2) is again de-activated for the following conditions:
•
•
•

5.4.3 Trace techniques
A test is carried-out prompted step-by-step using the SinuCom NC operator
interface. There are various trace techniques, which can be used to confirm
and log as to whether the test was positively carried-out.
TEXT Text entry by the operator
A table or cell for the user documentation is provided for the test. This should
then be completed corresponding to the specifications. In addition to how the
test is initiated, the text entry includes, e.g. the description of test situations and
responses or similar.
ALARM Alarms that have occurred are automatically logged
Specific system and user alarms expected for the test step that are
automatically logged after data trace has been started. After the appropriate
data has been traced, the selection of alarms to be logged can be reduced to
those alarms that are relevant for the specific test step.
TRC 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. After the
appropriate trace time (the relevant signal changes have taken place), then the
trace must be manually terminated.

The NCK returns the state (Alarm No. 27008) via the alarm "single-channel
software limit switch de-activated".
The single-channel software limit switches (set positions, refer to MD
36100 to MD 36130) are de-activated. This means that an axis can pass
these software limit switches without having to change the associated
machine data.
As a result of an NCK reset.
When an internal timer value expires that defines the maximum time that
the state can be active.
This timer value is set in the following machine data
MD 36958 $MA_SAFE_ACCEPTANCE_TST_TIMEOUT (NCK) and
MD 1358 $MD_SAFE_ACC_TEST_TIMEOUT (drive).
Automatically when the measured value trace has been completed.
If the monitoring function to be tested, that was active when selected, is no
longer active; e.g. when changing-over from SE1 to SE2 monitoring with
the mode active.
With the mode active, if the JOG NC mode is no longer active.
