LOGIC CNC INPUTS AND OUTPUTS.
(REF: 1402)
General modifiable signals.
DISCROSS1··n
It is applied to the cross compensation tables defined in the machine parameters. There is
a mark for each table.
The PLC sets the mark to (=1) to disable the table. The DISCROSS1 mark is for table 1,
DISCROSS2 for table 2 and so on.
PLCABORT
There is a mark for each channel. The mnemonics for each channel are the following.
PLCABORTC1 (can also be programmed as PLCABORT)
PLCABORTC2 PLCABORTC3 PLCABORTC4
If the PLC sets this mark low (=0), the CNC channel aborts the CNCEX command launched
from the PLC, but without initializing the conditions of the channel and keeping the history
of the channnel. This mark is only valid when the channel is executing a CNCEX; not in other
program or MDI executions.
Once the execution has been canceled, the CNC deactivates this mark and sets the FREE
mark of the channel high (=1). See "FREE" on page 295.
The PLCABORT mark is activated without having launched a CNCEX, the mark stays high
(=1) until a CNCEX is executed (which will be aborted automatically) or until it is deactivated
(RES PLCABORT).
PRGABORT
There is a mark for each channel. The mnemonics for each channel are the following.
PRGABORTC1 (can also be programmed as PRGABORT)
PRGABORTC2 PRGABORTC3 PRGABORTC4
If the PLC sets this mark low (=1), the CNC channel aborts the current execution of the part-
program; but without affecting the spindle, the rest of the history is initialized. Then, the CNC
resumes the execution of the program from the label indicated in the #ABORT instruction
that is active in the part-program.
If no #ABORT instruction is active in the part-program, the PRGABORT mark has no effect.
NEXTMPGAXIS
This mark may be used to select an axis sequentially for jogging it with the handwheel. Only
the axes being displayed in the active channel may be selected, regardless of the channel
they belong to. The axes of another channel cannot be selected if they are not being
displayed.
This mark is only taken into account when the CNC is in jog mode and the selector is in
handwheel mode. With an up flank of this mark, transition from (=0) to (=1), the CNC behaves
as follows.
• If no axis has been selected, it selects the first one that is displayed.
• If there is an axis selected, it selects the next one; if the last axis is selected, it selects
the first one again.
An axis is de-selected when quitting the handwheel mode using the movement selector and
after a reset.
This mark is meant for handwheels with push-button. On this type of handwheels, the push-
button may be used to select, sequentially, the axis to be jogged. The usual thing in these
cases is to connect the push-button of the handwheel to the digital input that will be in charge
of managing the NEXTMPGAXIS mark.
