Plane Select Parameters
Chapter 18
18-2
These subsections describe the parameters that are used to determine the
planes selected on the control when the G17, G18, and G19 codes are
programmed.
These parameters are available for plane selection. Note that the
parameters for G17, G18, and G19 have been combined in these
subsections. This is because the parameters are basically identical, with
the exception of the G-code that calls the plane.
Parameter: Page:
(G17, G18, G19) Primary Axis 1 18-4
(G17, G18, G19) 1st Axis Parallel to 1 18-5
(G17, G18, G19) 2nd Axis Parallel to 1 18-6
(G17, G18, G19) Primary Axis 2 18-7
(G17, G18, G19) 1st Axis Parallel to 2 18-8
(G17, G18, G19) 2nd Axis Parallel to 2 18-9
ATTENTION: Most cycles on the control are plane dependent.
Care should be taken when defining your coordinate planes.
Keep in mind that the axis you define as the 1st axis in the plane
is the abscissa, and the 2nd axis defining the plane is the
ordinate. The order these axes are assigned is significant to the
operation of fixed cycles, i.e., ZX plane is not the same as the
XZ plane.
If you intend to match your control’s operation identically to the
description in the user’s manual, you must use these primary plane
definitions:
