[Valid Data range] 1 to 8 (+ path number×10)
Specify both master and slave axis numbers.
When Flexible synchronous control between path is not used, the set
values must satisfy:
Master axis number ≤ slave axis number
When Flexible synchronous control between path is used, to specify
an axis in other path for master axis, set the value added the path
number ×10.
Slave axis must be in own path.
Ex.) Master axis : 1st axis in path 1.
Slave axis : 1st axis in path 2.
No.5660 in path 2 = 11
No.5661 in path 2 = 1 or 21
