Description:
Returns the current demand position set by the profiler.
When a move is not being profiled by the controller (i.e. when the axis is Idle), it is possible to set a
POSDEMAND. This will give a stepped response to the new demanded position.
The change in the demanded position from the current position cannot exceed the current value of
FOLERRORFATAL.

Description:
The theoretical spacing between the values in the compensation tables is set with the
PRECISIONINCREMENT keyword. If dual compensation tables are being used, the increment for the
forward and reverse tables must be the same.
The sign of the increment relates to the direction of the leadscrew in relation to the axis orientation.
Given a leadscrew defined as:
where fwd x are the actual values for travel in direction from A to B and rev x are the actual values for
travel in the direction from B to A. For single table compensation, the fwd x values would apply in both
direction.
If the leadscrew was laid in the machine such that travel from A to B results in a +ve change in axis
position, then the increment value is positive.
If the leadscrew was laid in the machine such that travel from A to B results in a -ve change in axis
position, then the increment value is negative.
