● Traversing motion is possible in spite of the external Stop C/D. This means that it is also
possible to test the active SBH monitoring state that results from an external Stop.
● An active stop in another axis does
- also for the setting MD36964 $MA_SAFE_IPO_STOP_GROUP = 0 for this axis.
● When traversing the axes using the JOG buttons, then the set speed limits are ignored -
such as e.g. MD32020 $MA_JOG_VELO - and the G0 value is activated as effective limit
value (maximum axis speed).
● The single-channel software limit switches (set positions, refer to MD36100 to MD36130)
are deactivated when testing SE. This means that an axis can pass these software limit
switches without having to change the associated machine data.
Prerequisites for the test step motion monitoring
A test step of the motion monitoring becomes active under the following conditions:
● 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 operating 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 SG1 is active, the acceptance test mode
is not active.
● 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:
● 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 time value is set in machine data MD36958
$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 interface. 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 initiated, 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
