Supplement: Synchro Specification Absolute Reset
The following are descriptions about the absolute reset methods for synchro specification axes.
The products ordered as the synchro specification are shipped after setting parameters to the
synchro specification. However, change the parameters when executing an absolute reset.
1. Synchro Axes
Synchro axes are comprised of the master axis (main axis) and the slave axis (sub-axis). The
axis of which the number is smaller becomes the master axis.
Program commands are valid only for the master axis. (Commands to the slave axis are
prohibited.)
As the absolute reset methods, there is the standard procedure and the special procedure. Which
procedure to be used is determined by the “each-axis parameter No. 38 encoder ABS/INC type”
values for the master and slave axes.
“Each-Axis Parameter No. 38 Encoder ABS/INC Type” Values
Master Axis Slave Axis
Absolute Reset Methods
1 1
Special procedure
1 0
Standard procedure
0 0
(When the value is 0 for both the master axis and the slave axis, both the axes are of the
increment specification.)
Example 1) When special procedure is executed for 2-axis controller:
Mode Transition:
Slave axis
Master axis with a smaller axis No.
Note: To change the axis No., use the F3 (Dev-) key or F4 (Dev+) key.
Example 2) When standard procedure is executed for 2-axis controller:
