Plane Select Parameters
Chapter 18
18-6
Notes
This is a global parameter; the value set here applies to all axes.
For Dual Processing controls, this is a per process parameter. The value set
in the parameters applies to all of the axes assigned to that process.
Important: If you are performing planar functions on parallel axes, both
the parallel axis and the primary axis must be defined to use the same
integrand word.
Function
Use this parameter to determine an axis that is parallel to primary axis 1
for this G-code. If no primary axes are used, this parameter is set
as “None.”
Up to 4 parallel axes can be set for a select plane. Up to two parallel axes
for each primary axis can be set. These parameters set the second of the
two possible axes that are parallel to the first primary axis in the G17, G18,
or G19 planes.
A parallel plane is selected in a part program by entering the name of the
axis that is parallel to the primary axis in the G-code block that calls the
plane. For example, if the G17 primary plane is the XY plane, and V is
determined with this parameter to be parallel to the primary axis 1,
programming
G17 V1;
would make the VY plane active.
A value for this parameter may be chosen from these allowable axis
names: A, B, C, U, V, W, X, Y, Z, $B, $C, $X, $Y, or $Z. A value of
“None” may also be selected indicating that there are not two axes parallel
to that primary axis in the plane selected with that G-code.
Important: Do not use this parameter if a value has not been set for the
parameter that assigns the 1st axis parallel to a primary axis.
