If Case A applies, the synchronization process can be started immediately. See step "Start synchronization". If Case B
applies, the offset "diff" must be calculated and taken into account:
● Measuring of diff
● By using two appropriate, right-angled reference points R and R" in the machine bed (at the right of the image), the
difference in position can be traversed in JOG. The diff offset can then be read as the difference in the position display.
The diff offset must be entered in the machine data of axis 3 (synchronized axis):
MD34100 REFP_SET_POS
Continue with Step 1 (see above).
● Start gantry synchronization. PLC sets:
DB380x.DBX5005.4 = 1 (start gantry synchronization)
Setting warning and trip limits
As soon as the gantry grouping is set and synchronized, the following machine data must still be set to correspond:
MD37110 GANTRY_POS_TOL_WARNING (gantry warning limit)
MD37120 GANTRY_POS_TOL_ERROR (gantry trip limit)
● Set the machine data for all axes with a large value to begin with:
MD37120 GANTRY_POS_TOL_ERROR (gantry trip limit)
● Set a very small value in the machine data:
MD37110 GANTRY_POS_TOL_WARNING (gantry warning limit)
When you put a heavy, dynamic strain on the axes, always be careful to re-enter the self-canceling alarm "10652
channel %1 axis %2 gantry warning limit exceeded".
● Now increase MD37110.
Do this until the alarm no longer appears. The interface indicates the status specified below. (That must occur in the
appropriate window, according to production.)
● Enter the value calculated for the warning limit + a small buffer value for safety purposes in machine data MD37120:
Values are entered in the following machine data:
MD37110 GANTRY_POS_TOL_WARNING (gantry warning limit)
MD37120 GANTRY_POS_TOL_ERROR (gantry trip limit)
MD37130 GANTRY_POS_TOL_REF (gantry trip limit for referencing)
These should have the following scales of magnitude at the end of the customizing process:
MD37110 < MD37120 < MD37130
me procedure must be followed when commissioning a gantry grouping in which the axes are operated by
and associated measuring systems.
The error limits entered into machine data MD37110 and MD37120 are considered to be additional tolerance va
lues for the
-value difference of the leading axis and following axis if the IS "Gantry is synchronous" is not present (e.g. to be
resynchronized after canceling alarms without the gantry grouping).
