S The single–channel software limit switches (set positions, refer to MD 36100 to
MD 36130) are de–activated when testing SE. This means that an axis can
pass these software limit switches without having to change the associated ma-
chine data.
Prerequisites for the test step motion monitoring
A test step of the motion monitoring becomes active under the following conditions:
S There is no active SI power on alarm for the axis to be tested.
S The pulses of the axis to be tested are enabled.
S JOG is active as NC operating mode.
S 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 SG1 is active, the ac-
ceptance test mode is not active.
S Both monitoring channels (NCK, drive) allow the mode to be activated. The
state that is assumed is subject to a crosswise data comparison between the
NCK and drive.
A test step is cancelled by the following conditions:
S As a result of an NCK Reset
S 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 parameter
p9558: SI motion, acceptance test mode, time limit.
Trace techniques
A test is carried out prompted step–by–step using the SinuCom NC operator inter-
face. There are various trace techniques, which can be used to confirm and log as
to whether the test was successfully completed.
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 initi-
ated, the text entry includes, e.g. a description of test situations and responses or
similar.
Alarms that occur are automatically logged
Specific system and user alarms expected for the test step that are automatically
logged after the data trace function 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.
