traversing ranges

Computational resolution and traversing ranges
The range of values of the traversing ranges directly depends on the selected computational
resolution (see Subsection "Resolution").
With the default assignment of the machine data for the computational resolution
• 1000 inc./mm
• 1000 inc./deg.
the following traversing ranges result:

Positioning accuracy of the control system

Computational resolution and traversing ranges
The positioning accuracy depends on:
• the computational accuracy (internal increments/(mm or degrees))
• 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.
