Effective value =
To keep the executed rounding more traceable, it is reasonable to use powers
to the 10th 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 limitation of the input limits depends on the display and input possibilities on
the operator panel.
This limit is reached at 10 digit positions plus decimal point plus sign.
Examples of programming in the
Supposed all linear axes of a machine will be programmed and traversed within
the range of values 0.1 ... 1,000mm.
To position exactly to 0.1mm, the computational resolution must be set to
