5DATA USED FOR POSITIONING CONTROL

5.1.4 Setting items for positioning data

MELSEC-Q

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".
