Angled Wheel Parameters
Chapter 35
35-9
Function
Use this parameter to select the angle of the wheel when the parameter
Wheel Angle Source is set to AMP. The Fixed Wheel Angle parameter
specifies the angle of the wheel axis as measured from the virtual axis.

Measure the wheel axis angle and enter its value (in degrees) for this
parameter. Angles can be entered for this parameter with up to three
decimal places. A wheel angle value equal to 90 degrees is invalid.
Range
0.000 to 180.000 degrees
Notes
The closer the wheel axis angle is to 90 degrees, the more transformed
motion must occur on the axial and wheel axes to perform virtual axis
moves. Depending on the axis display resolution for your system, wheel
axis angles approaching 90 degrees can result in transformed axis moves
larger than can be displayed on the position registers. When this occurs the
position registers change to dashes.
This is a global parameter. The value set here applies to all axes.
