11.4 Definition of a datum shift
Overview
As an alternative to the coordinate transformation Cycle 7 DATUM
SHIFT, you can use the TRANS DATUM plain-language function. Just
as in Cycle 7, you can use
TRANS DATUM to directly program shift
values or activate a line from a selectable datum table. In addition,
there is also the
TRANS DATUM RESET function, which you can
easily use to reset a datum shift.
TRANS DATUM AXIS
You can define a datum shift by entering values in the respective
axes with the
TRANS DATUM AXIS function. You can define up to
nine coordinates in one block, and incremental entries are possible.
Proceed as follows for the definition:
Show the soft-key row with special functions
Select the menu for defining various plain-language
functions
Select transformations
Select datum shifting with TRANS DATUM
Select the value input soft key
Enter the datum shift in the affected axes,
confirming with the
ENT key each time
Values entered as absolute values refer to the
workpiece datum, which is specified either by datum
setting or with a preset from the preset table.
Incremental values always refer to the datum which
was last valid (this may be a datum which has already
been shifted).
