 Synchro Function

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. A combination of master-axis and slave-axis numbers is set in axis-specific

parameter No. 65. The mating synchro axis is set for eaFKD[LV,IWKHD[LVLVQRWDV\QFKURD[LV³´LV

set.)

Example) 2-axis controller

(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)

HOME 1

(Do not perform home return on an absolute controller, except after an absolute reset.)

As a rule, the synchro function must be implemented by coupling the master-axis and slave-axis

sliders using a bracket, etc. 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.

2. Incremental Specification

With the incremental specification, the relative positioning of the master-axis and slave-axis sliders

remains fixed while the power is on. (If the sliders were moved while the power was turned off,

synchro movement will begin from the positions after the movement.)

Absolute reset is not performed on an incremental controller. Home return must be executed at

software reset after the power is turned on.

3. Absolute Specification (When both the master axis and slave axis are of the

absolute specification)

An absolute reset is performed after the relative positioning of the master axis and slave axis is

determined. Even when the sliders were moved while the power was turned off, the positions will be

corrected automatically when a servo ON (SVON) command is executed. (The slave slider will move

to the displayed coordinate position of the master slider in a fine-drive mode.)
