Axis Types
An axis can have several attributes, as specified below. Note that for most axis functions, it does not
matter what type of axis is used, or what letter is given it. However, for some features, only particular axis
names may be used.

Cartesian Axes
A Cartesian axis is one that may be put into a grouping of two or three axes so that movement along an
axis is a linear combination of motion on two or three motors. X, Y, and Z form one set of Cartesian axes;
U, V, and W form the other. In addition, there are several commands (NORMAL, circular move) that can
reference the X, Y, and Z-axes through the use of I, J, and K-vectors, respectively.
To make a Cartesian axis a linear combination of several motors, do so with an extended form of the axis
definition statement. For instance, a 30o rotation of the axes can be received from the motors with the
following axis definition statements:

To make a Cartesian axis a linear combination of several motors, do so with an extended form of the axis
definition statement. For instance, a 30o rotation of the axes can be received from the motors with the
following axis definition statements:
#1->8660.25X-5000Y
#2->5000X+8660.25Y
In this case, a request for a Y-axis (or an X-axis) move would cause both motors #1 and #2 to move.
Only the X, Y, and Z Cartesian axes may be used for PMAC’s circular interpolation routines, cutter radius
compensation routines, and matrix axis transformation routines. If you want to do circular interpolation on
other axes, you can do it through blended short moves and trigonometry in subroutines.
