QWERTYOFF1
··
QWERTYOFF8
If the PLC turns one of these marks on, it disables the corresponding alphanumeric keyboard.
Each mark may be used to disable a USB keyboard (10K model) or one integrated into the
CAN bus (15" model) ; the rest of the elements of the bus are not affected. The keyboards
are not enabled or disabled immediately, especially when activating the USB keyboard, it may
take a few seconds.
The way the QWERTYOFF1 works depends on the CNC model.
• On the 10K model, this mark affects the alphanumeric keyboard and the softkeys of the
monitor (USB interface).
• On the 15" model, this mark affects the softkeys of the monitor (USB interface) and the
first node of the CAN bus. In order for the mark to affect the keyboard associated with
the central unit, the number of this keyboard must be the lowest one in the bus.
Marks QWERTYOFF2 to QWERTYOFF8 affect the rest of the CAN keyboards, depending
on the logic numbers of the nodes, from lowest to highest.
FLIMITAC
If the PLC activates this mark, the CNC activates the feedrate safety limits (parameter
FLIMIT) on all the axes of the system during the execution of the block. If the PLC deactivates
this mark, the CNC restores the programmed feedrate.
The feedrate safety limit is applied to the movements in automatic (G0, G1, etc.) and in jog
mode (jog, handwheels, etc.). This parameter affects neither the threading operations nor
the independent axis movements, which are executed at the programmed feedrate.
FLIMITACCH
There is a mark for each channel. The mnemonics for each channel are the following.
FLIMITACCHC1 (can also be programmed as FLIMITACCH)
FLIMITACCHC2 FLIMITACCHC3 FLIMITACCHC4
If the PLC activates this mark, the CNC activates the feedrate safety limits (parameter
FLIMIT) on all the axes of the channel during the execution of the block. If the PLC deactivates
this mark, the CNC restores the programmed feedrate.
The feedrate safety limit is applied to the movements in automatic (G0, G1, etc.) and in jog
mode (jog, handwheels, etc.). This parameter affects neither the threading operations nor
the independent axis movements, which are executed at the programmed feedrate.
SLIMITAC
If the PLC activates this mark, the CNC activates the speed safety limits (parameter SLIMIT)
on all the spindles of the system during the execution of the current block. If the PLC
deactivates this mark, the CNC restores the programmed speed.
INT1
··
INT4
There is a mark for each channel. The mnemonics for each channel are the following. Here
is an example of the mnemonics for INT1; it is the same for the rest of the marks.
INT1C1 (can also be programmed as INT1)
INT1C2 INT1C3 INT1C4
When the PLC activates one of these marks, the channel interrupts the execution of the
program and executes the corresponding interruption subroutine associated with
parameters INT1SUB to INT4SUB. The CNC executes the subroutine with the current history
of the interrupted program (G functions, feedrate, etc.). Once the subroutine is executed, the
CNC resumes the execution of the program from the interruption point and maintaining the
changes made to the history by the subroutine (G functions, etc.).
