2.1.3 Positioning accuracy of the control system
Actual-value resolution and computational resolution
The positioning accuracy of the control depends on the actual-value resolution (=encoder
increments/(mm or degrees)) and the computational resolution (=internal increments/(mm or
degrees)).
The coarse resolution of these two values determines the positioning accuracy of the control.
The input resolution, interpolator and position-control cycle selections have no effect on this
accuracy.
