Chapter 9 Major Positioning Control
9.2 Setting the positioning data
9.2.1 Relation between each control and positioning data
The setting requirements and details for the setting items of the positioning data to be
set differ according to the "
Da.2 Control system".
The following table shows the positioning data setting items corresponding to the
different types of control. Details and settings for the operation of each control are
shown in Section 9.2.2 and subsequent sections.
(In this section, it is assumed that the positioning data setting is carried out using
GX Works2.)
