The range of values of the traversing ranges directly depends on the selected
computational resolution (see Subsection 10.3.1, page 10-281).
With the default assignment of the machine data for the computational
resolution
S
1,000 increments/mm
S
1,000 incr/degr.
the following traversing ranges result:
Traversing range in the metric system
" 999,999.999 [mm; degrees]
" 999,999.999 [mm; degrees]
" 999,999.999 [mm; degrees]
The positioning accuracy depends on:
S
the computational accuracy (internal increments/(mm or degrees))
S
the actual-value resolution (encoder increments/(mm or degrees)).
The rougher resolution of both determines the positioning accuracy of the NC.
The input resolution, the position control and interpolation clock do not affect the
accuracy.
