12.6 Defining coordinate transformations
Overview
As an alternative to the coordinate transformation Cycle 7,
DATUM
SHIFT
, you can also use the
TRANS DATUM
conversational 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 that can
be used to easily reset a datum shift.
In the optional machine parameter
CfgDisplayCoordSys
(no. 127501) you can specify the coordinate system in
which the status display shows an active datum shift.
TRANS DATUM AXIS
Example
13 TRANS DATUM AXIS X+10 Y+25 Z+42
You can define a datum shift by entering values in the respective
axis 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
Press the
PROGRAM FUNCTIONS
soft key
Select transformations
Select the
TRANS DATUM
datum shift
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 numbers refer to the
workpiece preset, which is specified either by presetting
or by selecting 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).
