Example of rounding:
Computational resolution: 1000 increments/mm
Programmed path: 97.3786 mm
Effective value = 97.379 mm
Note
To keep rounding easily understandable, it is better to use powers of 10 for the
computational resolution (100, 1000, 10,000).
In MD 9004: DISPLAY_RESOLUTION you can set the number of decimal
places after the decimal point for the position values on the operator panel.
The input value limitation depends on the display options and input options of
the operator panel.
This limit is 10 decimal places plus decimal point plus sign.
Example of programming in the
1
/
10
– mm range:
All the linear axes of a machine are to be programmed and traversed within the
value range 0.1 ... 1000 mm.
To position to 0.1 mm accuracy, the computational resolution must be set to
10

incr./mm:
MD 10200: INT_INCR_PER_MM = 10000 [incr./mm]:
Example of related part program:
N20 G0 X 1.0000 Y 1.0000 ; Traverse axis to position
X=1.0000 mm, Y=1.0000 mm;
N25 G0 X 5.0002 Y 2.0003 ; Traverse axis to position
X=5.0002 mm, Y=2.0003 mm
