5.3.1 Overview
[1] Common Items (Applicable to both the absolute specification and incremental specification)
Synchro axes consist of a master axis and a slave axis. The axis with the smaller axis number
becomes the master axis.
For the synchronizing band between Single-Axis and Cartesian in RX/SX controllers and R/S
Controllers, it is necessary to have 4 pairs at the most of combinations.

A combination of master-axis and slave-axis numbers is set in axisspecific parameter No. 65. The
mating synchro axis is set for each axis. (If the axis is not a synchro axis, “0” is set.)
Example) 2-axis connection

(Note) The settings of other parameters vary partially between the absolute specification and
the incremental specification.
Movement commands in the program are valid only for the master axis. The position data of the
slave axis will be ignored.
Only the master axis executes home return (including home return following an absolute reset).
Example)

(Note) Do not perform home return on an absolute controller, except after an absolute reset.
�
Consider the relative positioning of the master-axis and slave-axis sliders so that the slave slider
will not contact the mechanical ends during home return or full-stroke movement.
