Configuring Axes
Chapter 3
3-4
Important: The axes must be named in a consecutive series; fitted axes
cannot follow an unfitted axis. Any fitted axes that follow an unfitted axis
are ignored by the control. Any motor using the auxiliary outputs
(CN8/TB2 on 3-axis digital or analog servo modules, TB2 on 4-axis servo
modules) must be configured as the last axis (typically, a spindle axis) in
the consecutive series of named axes.

Typical linear axis names for mills and surface grinders are:
X, Y, Z
Typical rotary axis names are:
A, B, C
where the axis of rotation for A, B, and C is X, Y, and Z respectively.
Typical parallel linear axis names for mills are:
U, V, W
where U, V, and W are parallel to X, Y, and Z respectively.
Typical linear axis names for lathes and cylindrical grinders are: X and Z
The typical rotary axis name for a lathe is: C
where the axis of rotation for C is Z.
Typical parallel linear axis names for lathes are:
U, W
where U and W are parallel to X and Z respectively.
Typical auxiliary linear axis names are:
$X, $Y, and $Z
Typical auxiliary rotary axis names are:
$B and $C
Important: The axis name S is reserved as the name for spindle axes.
Do not use S for linear or rotary axes
