14.16 Subroutine associated with the command #CUTTING ON and
#CUTTING OFF.
The command #CUTTINGON executes the associated subroutine after updating the cutting
variables ((V.)TTCUT.name). The command #CUTTINGON executes the associated
subroutine. Both commands are specifically for laser machines, where these subroutines
must perform the initial associated cutting operations.
Management of the CUTTING mark in the subroutine.
The OEM must manage the CUTTING mark from these subroutines. At the start of the
associated subroutine #CUTTING ON (or when the OEM deems it necessary), the OEM
must activate the CUTTING mark (assigning it a value of 1) to indicate to the PLC that it
should start the cutting operation. At the end of the associated subroutine #CUTTING OFF
(or when the OEM deems it necessary), the OEM must deactivate this mark (assigning it
the value 0) to indicate to the CNC that it has finished the piercing operation.
• The instruction #PLC makes it possible to manage a PLC mark from the part or subroutine
program, without interrupting the block preparation.
• This mark shows the state of the variable V.PLC.CUTTING. The OEM can also use this
variable in the subroutines associated with cutting (by default, Cuttingon.fst /
Cuttingoff.fst) to modify the status of this mark. Entering this variable interrupts the block
preparation.
14.16.1 Configure the subroutines.
Assign the subroutine to the command.
Name and location of the subroutine.
These subroutines associated must be defined for the general parameters CUTTINGON (by
default, Cuttingon.fst) and CUTTINGOFF (by default, Cuttingoff.fst). Both subroutines must
be saved in the folder ..\Mtb\Sub. If there are several channels, there may be a different
subroutine for each channel.
Since it is an OEM subroutine with an .fst extension, the CNC loads this subroutine into the
RAM of the CNC. See
"14.1 Run subroutines from RAM (extension *.fst)." on page 617.
Subroutines specifically for the laser model. The subroutines supplied by Fagor provide basic laser
management, so they should be configured appropriately by the OEM. The OEM is responsible for
ensuring that the subroutine complies with all safety aspects relating to handling the laser.
If this version is updated, the CNC behaves as follows.
• For the two first two installation options, the CNC will only copy the subroutines in the folder
..\Mtb\Sub if they do not already exist.
• In the third installation option, "rename previous version and install it completely", the CNC always
updates the subroutines.
Parameter. Meaning.
CUTTINGON CHN Subroutine associated with the command #CUTTING ON.
CUTTINGOFF CHN Subroutine associated with the command #CUTTING OFF.
[CHN] ....... General machine parameter of the channel.
