8.1.5 External Alteration of the Piercing Time
The piercing time specified in G24 can be changed using an external
signal.
(1) Extending the piercing time
If the "extension" signal is turned on during piercing, piercing
continues as long as the signal remains on. When it is turned off,
piercing ends, and the next block is executed.
Preset time
External “extension"
(2) Reducing the piercing time
If the "reduction" signal is turned on during piercing, piercing
discontinues when the signal rises, and the next block is
executed.
Preset time
External “reduction"
(3) Updating the piercing time
When an external "extension" or "reduction" signal is used, the
corresponding value in the laser data area can be updated. If
the program contains G24; , it can run with the updated time.
