5 DATA USED FOR POSITIONING CONTROL
5.1.4 Setting items for positioning data
Positioning data must be set for carrying out any "major positioning control". The table
below lists the items to be set for producing the positioning data.
One to 600 positioning data items can be set for each axis.
For details of the major positioning controls, refer to Chapter 9 "Major Positioning
Control". For details of the individual setting items, refer to Section 5.3 "List of
positioning data".

:Set as required (Read "–" when not required.)
:Setting not possible
– :Setting not required.
(This is an irrelevant item, so the set value will be ignored. If the value is the default value or within the setting range, there is no problem.)
:Two control systems are available: the absolute (ABS) system and incremental (INC) system.
