Angled Wheel Parameters

Function
Use this parameter to tell the control the virtual diameter axis location of
the wheel axis center of rotation. This location is measured from the zero
point of the virtual diameter axis (typically X) to the center of rotation for
the wheel axis (typically W).

All [619]
Always measure the Wheel Virtual Diameter Offset from the Wheel
Position at Rotation Center. The Wheel Virtual Diameter Offset is an
incremental distance measured perpendicular 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.
