Continue with Step 1 (see above).
● Start gantry synchronization. PLC sets:
V380x 5005.4 = 1 (start gantry synchronization)
6.7.4 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)
Proceed as follows
● 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:
Error limit values
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)
