6 NC Machine Data (NC MD), NC Setting Data (NC SD)
6.6.1 General MD bits (general bits)
NC MD
5002
Possible combinations
See table for MD 18 000
Default value:
For combinations with display resolution (NC MD 1800*) and position control resolution
(NC MD 1800*).
Active on:
The input resolution (IS) defines the incremental weighting for entering and displaying values.
At the same time the initial setting G70 (inches) or G71 (mm) is defined.

All linear axes and rotary axes of the control can be defined with an axis-specific position
control and display resolution. The input resolution and the resulting geometrical resolution
(used for programming, TO, ZO, interpolation...) is defined once for the whole control (detail
description see Section entitled "Axis (Analog) and Spindle Installation").
With these axis-specific resolutions (detailed description see Section entitled "Axis (Analog)
and Spindle Installation") the demands of the machine regarding
• maximum velocity
• varying precision
• maximum traversing range
can be optimally met.
Input resolution NC MD 5002 bit 4 to 7
Axis-specific display resolution NC MD 1800* bit 4 to 7
Axis-specific position control resolution NC MD 1800* bit 0 to 3
