Checking the transition to the special mode "Safe motion"
At
"Check for transition to SMM:", the special mode "Safe motion" (SMM) for
which the transition is to be checked. Afterwards, call the oscilloscope function
via the link in the dialog. When the oscilloscope is started, the measuring
signals for the selected SMM already are automatically configured.
● Trigger: P‑0‑3262, SMO: Selected operating state, bit 3..18
● Measuring signals:
The oscilloscope can be activated via the "Start" button. It is now necessary
to go to an operating status (normal operation or another special mode
"Safe motion") from which the chosen SMM can be selected. In this status,
the axis has to be moved with the maximum allowed velocity and load and go
to the chosen SMM via the selection. Make sure that the transition does not
cause delay monitoring functions or time monitoring functions to trigger. With
the corresponding oscilloscope measurement, the check can be accordingly
documented.
The following error messages signal incorrect transition:
● F7051 Safely-monitored deceleration exceeded
● F8351 Safely-monitored deceleration exceeded
● F7050 Maximum transition time exceeded
● F8350 Maximum transition time exceeded
During the transition, the threshold of deceleration monitoring is displayed in
the recorded parameter "P-0-3238, SMO: Active velocity threshold.
This check should be repeated for all other operating states from which the
chosen SMM can be selected.
It is not necessary to check the transition from the special mode
"Emergency stop" (SMES) and the special mode "Safe standstill" (SMST1 or
SMST2) to the special mode "Safe motion", because in these cases direct
switching (without transition) is always carried out.
If multiple special modes "Safe motion" have been configured, the check should
be repeated for each configured SMM.
In the bottom section of the dialog ("Transitions check" tab page), the test
progress can be documented using the memo. The "Transitions check" tab
page contains one row for each possible change in the operating status. In
the "Used" column, the commissioning engineer marks all changes in the oper-
ating states relevant to the axis and only checks these changes. The successful
checks can be documented in the "OK" column in the corresponding transi-
tions.
Via the "Screenshot" button, a screenshot of the tab page can be copied to the
clipboard for the purpose of documentation.

Before starting to check the transition, make sure that
the braking ability and the overrun distance are suffi-
cient. If this is not the case, the test cannot be carried
out. If necessary, adjust the deceleration for this axis.
