The Actual Corrected Position feedback query .This property returns the position feedback generated by the motion profiler after the correction value added to it. When no correction is used (i.e all the comp tables involves the axis as its target is inactive) then this value would be identical to the Axis.Pfb.

Examples
<comp>.SourceData[1][15] = 120.0 ‘position on axis
<comp>.TargetData[1][15] = 0.125 ‘correction value regarding SourceData position
Move <axis> 120.0
Print <axis>.Pfb
--> 120.0 ‘ (it’s the “expected user value”)
Print <axis>.CompPfb
--> 120.125 ‘(it’s the “real value”)
