2.9.4 Program display modes via an additional basic block display
Basic block display (only for ShopMill/ShopTurn)
A second socalled basic block display can be used with the existing block display to show all
blocks that produce an action on the machine.
Look Ahead basic block display
The actually approached end positions are shown as an absolute position. The position
values refer either to the workpiece coordinate system (WCS) or the settable zero system
(SZS).
The number of Look Ahead display blocks stored in the display buffer depends on the
number of prepared blocks in the NCK preprocessing buffer in the relevant processing state.
If a preprocessing stop is processed, the number of display blocks is reduced to zero and
increases again after the stop is acknowledged. In the case of REORG events (e.g., mode
change, ASUB start), the display blocks stored for Look Ahead are deleted and
preprocessed again afterwards.
Processed values
Values processed in the basic block display coincide with the:
• selected tools
• feed and spindle speed
• actually approached position values
exceptions:
With active tool radius compensation, deviations can occur.
For modulo axes, the programmed value is displayed in the basic block display. This
value can also lie outside the modulo range.
Note
As a basic rule the positions are represented in the WCS or the SZS.
The basic block display can be activated or deactivated with setting data
SD42750 $SC_ABSBLOCK_ENABLE.
