CNC VARIABLES.
(REF: 1402)
Variables related to the machine configuration.
Syntax.
·ch· Channel number.
·xn· Name, logic number or index of the axis.
Remarks.
There are two software limits; the CNC always applies the most restrictive one.
These variables keep their value after a Reset, they are initialized with the maximum value
possible when turning the CNC on.
KINETIMATICS DIMENSIONS.
(V.)[ch].A.HEADOF.xn
Variable that can only be read from the program, PLC and interface.
Variable valid for rotary and linear axes.
The variable returns the execution or preparation value.
Dimension in each axis of the kinematics.
Syntax.
·ch· Channel number.
·xn· Name, logic number or index of the axis.
Remarks.
The variable returns the value of execution or preparation as follows. If the axis is consulted
through its logic number, the variable always returns the preparation value. In the rest of the
cases, if the axis belongs to the channel requesting the variable, it returns the preparation
value; if the axis belongs to a different channel, the variable returns the execution value and
interrupts block preparation.
This variable returns the resulting measurement of the active kinematics on that axis. It may
be a particular value of TDATA (kinematics table) or the combination of several of them
depending on the type of kinematics.
CHANGE THE TURNING DIRECTION ASSIGNED TO M3 AND
M4.
(V.)[ch].A.POLARITY.sn
(V.)[ch].SP.POLARITY.sn
Variable that can be read and written via program, PLC and interface.
Variable valid for rotary and linear axes as well as for spindles.
The variable returns the execution value; reading it interrupts block preparation.
This variable may be used to reverse the meaning of spindle parameters POLARM3 and
POLARM4 that set the spindle turning direction for M3 and M4. The variable does not modify
the values of the machine parameters.
If the spindle is turning in open loop (M3/M4), the CNC does not apply the changes of this
variable immediately; the CNC applies the changes the next time a speed or an M3/M4 is
programmed.
