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).
