Angled Wheel Parameters

Function
Use this parameter to select how the angle of the wheel axis is to be
determined. The following table shows the available methods to determine
the wheel axis angle source:
Use this Source: When:
AMP a fixed angle from AMP is used. This method requires AMP to be
re-configured and downloaded when the wheel axis angle changes.
Use this method for machines with rigid or seldomly changed wheel
axes angles. Use the AMP parameter Fixed Wheel Angle to enter
the value of this angle. Angles measured to three decimal places.
PAL PAL ladder logic controls the active wheel angle. Use this method
when the wheel axis angle is adjustable through some manual method
or an open loop rotary axis. Refer to your 9/Series PAL Reference
Manual for details (see PAL flags $WHANGLE and $WHREIN).
Angles measured to two decimal places.
Rotary Axis a closed loop rotary axis is used to change the wheel axis. Feedback
from this rotary axis is used to determine the angle that is to be used
as the wheel axis angle. Use the AMP parameter Wheel Rotary Axis
Name to select this rotary axis. Angles measured up to axis
resolution.
