10.7 Modifying presets

The control provides the following functions for modifying a preset
directly in the NC program after it has been defined in the preset
table:
Activate the preset
Copy the preset
Correct the preset

Activating a preset

The PRESET SELECT function allows you to use a preset defined in
the preset table and activate it as a new preset.
To activate the preset, use the preset number or the entry in the Doc
column. If the entry in the Doc column is not unique, the control will
activate the preset with the smallest preset number.
If you program PRESET SELECT without optional
parameters, the behavior is the same as with Cycle 247
SET PRESET.
Use the optional parameters to define the following:
KEEP TRANS: Retain simple transformations
Cycle 7 DATUM SHIFT
Cycle 8 MIRRORING
Cycle 10 ROTATION
Cycle 11 SCALING FACTOR
Cycle 26 AXIS-SPECIFIC SCALING
WP: Any changes apply to the workpiece preset
PAL: Any changes apply to the pallet preset (option 22)
Procedure
Proceed as follows for the definition:
Press the SPEC FCT key
Press the PROGRAM DEFAULTS soft key
Press the PRESET soft key
Press the PRESET SELECT soft key
Define the desired preset number
As an alternative, define the entry from the Doc
column
Retain the transformations where necessary
If necessary, select the preset to which the
change is to apply
