Activating/Deactivating A Function - HEIDENHAIN iTNC 530 User Manual

Activating/deactivating a function

Global program settings remain active until you manually
reset them. Note that your machine tool builder can
provide functions with which you can set and reset global
program settings also under program control.
If a global program setting is active, the TNC shows
the symbol in the position display.
If you use the file manager to select a program, the TNC
displays a warning message if global settings are active.
Then you can simply acknowledge the message with the
soft key or call the form directly to make the changes.
Global program settings have no effect in the smarT.NC
operating mode.

If you activate more than one global program setting, the
TNC calculates the transformations internally in the
following sequence:
1: Basic rotation
2: Axis swapping
3: Mirror image
4: Shift
5: Superimposed rotation
The remaining functions such as axis locking, handwheel
superimposition and feed rate factor act independently.
