Setting the machine parameters.
2.1.6 Subroutines related to the –M– functions.
i
The following parameters correspond to the –M– function table.
MPROGNAME
Name of subroutine associated with M function.
Possible values: any text with up to 64 characters.
Default value: Without subroutine.
Associated variable: (V.)MPM.MPROGNAME[pos]
Parameter included in the DATA table.
Execution channels
The subroutines associated with the M functions must be located in the "C:\CNC8070 \MTB
\SUB" folder.
When associating a subroutine with an M function, the execution of the M function executes
the associated subroutine without executing the M function itself. To send the M function to
the PLC, it must be programmed in the subroutine.
The type of synchronization of the M functions that have an associated subroutine must be
"without synchronization" or "After-After". The CNC executes the associated subroutine after
executing the programmed movement (if any).
To have different procedures in the subroutines associated with certain M functions, the code of each
channel may be differentiated within the subroutine using the variable (V.)G.CNCHANNEL..
SYNCHTYPE
Type of synchronization.
Possible values: Without synchronization / Before-Before / Before-After / After-After.
Default value: Before - Before.
Associated variable: (V.)MPM.SYNCHTYPE[pos]
Parameter included in the DATA table.
Since the M functions may be programmed together with the movement of the axes, in the
same block, it must be indicated when the function is to be sent out to the PLC and when
it will be checked that it has been already executed (synchronization).
Type of synchronism. Meaning.
Without synchronization. M function not synchronized.
Before - Before. The M function is sent to the PLC and synchronized before the
movement.
Before - After. The M function is sent to the PLC before the movement and
synchronized after the movement.
After - After. The M function is sent to the PLC and synchronized after the
movement.
The M functions may be sent and/or synchronized before or after the movement.
If an M function is used to turn on a lamp, it will be set without synchronization because
there is no need to check that the lamp has indeed turned on.
Functions M03 and M04 to start up the spindle, they should be executed and
synchronized before the movement.
Function M5 to stop the spindle, should be executed and synchronized after the
movement.
