10.2.5 Permissible resolution combinations
Permissible resolution combinations
Input resolution, display resolution and position control resolution can be defined in any
combination within certain limits (see the following two tables). Please note that a factor of
max. 200 between input resolution and position control resolution for all axes together is
possible.
Example:

Note:
Excessive differences between position control resolution and input resolution ought to be
avoided. For example, an input resolution of 10
-5
of 0.5 - 10
position control resolution units.
If the units of both position control and input resolution belong to the same unit system (metric,
inches, degrees), the display resolution and the position control resolution must be equal (see
table above).
If the units of the position control and input resolution do not belong to the same unit system,
the display resolution must be set according to the table above.
As a matter of principle, the same unit system must be used for the display resolution and the
input resolution.
Note:
As from SW 4, the position control and display resolution for the rotary axes must not exceed
the input resolution.
_______
1) Bit "High-resolution rotary axis" must be set for rotary axes. For input resolution 10
message 4 "System of units illegal" is output.
