This diagram shows how input values are converted into internal units.
It also shows the following conversion to internal increments/(mm or degrees), which can
cause loss of decimal places if the computational resolution was selected to be coarser than
the input resolution.
In addition, it provides an overview of the following topics:
• Selection of measuring system (metric/inch)
• Scaling of physical quantities of machine and setting data
• Conversion of basic system
• Setting of computational resolution
One example is the conversion of a physical quantity
(MD36110 $MA_POS_LIMIT_PLUS)
depending on the machine data parameterization
(MD10230 $MN_SCALING_FACTORS_USER_DEF,
MD10220 $MN_SCALING_USER_DEF_MASK).
2.1.5 Input/display resolution, computational resolution
Resolutions: Differences
The following types of resolution, e.g. resolution of linear and angular positions, velocities,
accelerations, and jerk, must be differentiated as follows:
• Input resolution
Data is input via the control panel or parts programs.
• Display resolution
Data is displayed via the control panel.
• Computational resolution
Data input via the control panel or parts program is displayed internally.
The input and display resolution is defined via the control panel being used, whereby the
display resolution of position values can be changed with machine data:
MD9004 $MM_DISPLAY_RESOLUTION.
Machine data:
MD9011 $MM_DISPLAY_RESOLUTION_INCH
can be used to configure the display resolution of position values using the inch system.
This allows you to display up to six decimal places with the inch setting.
For the programming of parts programs, the input resolutions listed in the Programming
Guide apply.
