CNC VARIABLES.
(REF: 1402)
Variables related to the machine parameters of the channels.
"RETRACE" FUNCTION.
(V.)[ch].MPG.RETRACAC
Variable that can only be read from the program, PLC and interface.
The variable returns the value of block preparation.
Channel [ch]. Permit enabling the "retrace" function
Syntax.
·ch· Channel number.
Values of the variable.
This variable returns one of the following values.
(V.)[ch].MPG.NRETBLK
Variable that can only be read from the program, PLC and interface.
The variable returns the value of block preparation.
Channel [ch]. Maximum number of blocks allowed for the "retrace" function.
Syntax.
·ch· Channel number.
(V.)[ch].MPG.RETMFUNC
Variable that can only be read from the program, PLC and interface.
The variable returns the value of block preparation.
Channel [ch]. Treatment of the M functions with the "retrace" function.
This parameter sets the behavior of the "retrace" function when executing M functions. When
the CNC finds an M function, it can either ignore it and keep executing blocks in retrace or
cancel the "retrace" function.
Syntax.
·ch· Channel number.
Values of the variable.
This variable returns one of the following values.
Remarks.
This parameter does not affect the following "M" functions.
• Functions M00 and M01 are always executed; they are sent to the PLC and [CYCLE
START] must be pressed to resume execution in retrace.
• Functions M03 and M04 are always ignored; the CNC does not start the spindle nor does
it change its turning direction.
• Function M05 cancels the "retrace" function; the CNC does not stop the spindle.
