3.5.3 Program Sequence Modification
Skip levels:
■ The program blocks which are marked as active
skip levels are not executed when the program is
being carried out.
■ Skip levels: 0..9
■ For multiple skip levels, enter a sequence of digits
■ Deactivate the skip level: No entries in ”Level No.”
Operation:
Select menu item ”Process - Skip level”
Enter the level number
Quantity
■ Counting range: 0..9999
■ Quantity = 0: Production without quantity limitation;
the counter is increased by one after each program
run.
■ Quantity > 0: The CNC PILOT produces the defined
quantity; the counter is reduced by one after each
program run.
■ Quantity counting is retained even if the machine
has been switched off in the meantime.
■ When an NC program is activated with ”Program
selection,” the CNC PILOT resets the quantity
counter.
■ When a program has completed a production lot,
the NC program cannot be restarted by the Cycle
Start key. To start the NC program again, press
”Re-start.”
Operation:
Select menu item ”Process – Quantity”
Enter the quantity
V variables
■ The ”V variables” dialog box serves for input and
display of variables.
■ V variables are defined at the beginning of the NC
program. The meaning is specified in the NC
program.
Operation:
Select the menu item ”Process – V variables” –
the CNC PILOT shows the variables defined in the
NC program
Press ”Edit” if you wish to change the variables
Status of skip levels
Display field:
Markings:
■ Upper row: entered skip levels
■ Lower row: the skip levels detected by the ”block execution”
(active skip levels)
The CNC PILOT accounts for activated/deactivated skip
levels after approx. 10 blocks (reason: block scan during
the execution of NC blocks).
