SI acceptance test
The following rule applies with the start of the SI acceptance test:
● The alarm suppression possibly set in MD10094
$MN_SAFE_ALARM_SUPPRESS_LEVEL is not taken into account.
Test step, motion monitoring
With the start of a test step of the motion monitoring (e.g. SBH, SG) the following conditions
apply:
● Alarm "Acceptance test mode active" NCK (Alarm No. 27007) and drive (fault No. C01799)
is output.
● The setpoint velocity limiting set using MD36933 $MA_ SAFE_DES_VELO_LIMIT is
deactivated. This allows the axis to be traversed in spite of the fact that the SBH monitoring
is active or a traversing speed greater than the actual SG monitoring without having to
change the selected reference (setpoint) speed limiting.
● SI power on alarms can be temporarily acknowledged with a reset so that after an SBH
response has been tested for an axis, an NCK reset does not have to be initiated for the
fault acknowledgment. This involves the acknowledgment criteria for the following alarms:
Alarm
No. NCK
27010
27023

Purpose of the test step
Test the internal Emergency Stop functionality when executed via external stop
responses and the response to the external SPL I/O.
Test all of the states relevant for the safety functions that should be first docu‐
mented within the scope of a function table or similar (interdependency of sensor
signals, positions, modes). In this case, the following should be taken into account
– the active monitoring function for SI-monitored axes (internal safety functions)
and the switching state of safety-related external SPL output peripherals (I/O).
Check the response when provoking that the SBH limit values are violated and
define associated characteristic quantities/parameters.
Test the response when provoking that the SG limit values are violated and define
associated characteristic quantities/parameters.
Test the response when provoking that the SE limit value is violated and define
associated characteristic quantities/parameters.
When the brake is closed, the drive generates an additional torque that must not
result in any axis motion.
The test results are saved and downloaded.
The acceptance report is generated based on the test results that have been
determined.
