Angled Wheel Parameters
Chapter 35
35-12
Function
Use this parameter to tell the control the axial location of the wheel axis
center of rotation. This location is measured from the zero point of the
axial axis (typically Z) to the center of rotation for the wheel axis
(typically W).

All [618]
Always measure the Wheel Axial Offset from the Wheel Position at
Rotation Center. The Wheel Axial Offset is an incremental distance
measured parallel to the axial axis and is independent of the angle of the
wheel axis.
Range
--100000.00000 to 100000.00000 in.
or
--25400000.00000 to 25400000.00000 mm
Notes
This is a global parameter. The value set here applies to all axes.
Most often this intersection occurs at the wheel axis center of rotation in
which case this parameter would be set to zero. You only need to enter a
value for this parameter if your wheel axis center of rotation is not about
the axial axis zero point.
