The range of values of the traversing ranges directly depends on the selected
computational resolution (see Section 11.3.1, Page 11-292).
With the default assignment of the machine data for the computational resolution
S 1000 inc./mm
S 1000 inc./deg.
the following traversing ranges result:
Traversing range in the metric system
 999,999.999 [mm; deg.]
 999,999.999 [mm; deg.]
 999,999.999 [mm; deg.]
The positioning accuracy depends on:
the computational accuracy (internal increments/(mm or degrees))
S
the actual--value resolution (encoder increments/(mm or degrees)).
S
The rougher resolution of both determines the positioning accuracy of the NCK.
The input resolution, the position control and interpolation clock do not affect the
accuracy.
