Input/display resolution, computational resolution
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 part programs.
●
Display resolution - data is displayed via the control panel.
●
Computational resolution - data input via the control panel or part program is displayed
internally.
The input and display resolution are determined by the control panel used (display machine
data), whereby the display resolution for position values/spindle speed can be modified using
MD203 DISPLAY_RESOLUTION (display resolution, metric linear position, general angular
position) or MD205 DISPLAY_RESOLUTION_SPINDLE (display resolution for spindle
speed).
MD204 DISPLAY_RESOLUTION_INCH can be used to configure the display resolution for
linear position values in inches.
For the programming of part programs, the input resolutions listed in the Programming Guide
apply.
The desired computational resolution is defined via MD10200 INT_INCR_PER_MM
(computational resolution for linear positions) or MD10210 INT_INCR_PER_DEG
(computational resolution for angular positions). It is independent of the input/display
resolution but should have at least the same resolution.
The max. number of places after the decimal point for position values, velocities etc. in the
part program and the number of places after the decimal point for tool offsets, zero offsets
etc. (and therefore also for the maximum possible accuracy) are defined with the calculation
resolution.
The accuracy of angle and linear positions is limited to the computational resolution by
rounding the product of the programmed value with the computational resolution to an
integer number. To make the rounding clear, powers of 10 should be used for the calculation
resolution.
Example of rounding:
Computational resolution: 1000 increments/mm
Programmed path: 97.3786 mm
⇒ effective value = 97.379 mm
