1.2 Components of axes
In synchronization operation, an axis for which a move command can be issued is called the
master axis, and an axis for which movement is performed in synchronization with that for
the master axis is called a slave axis.
By setting the axis number of a master axis in the parameter (No.8311) of the slave axis, the
axis configuration for this function is determined.
One master axis can have multiple slave axes.
Example 1) When three sets is used:
When the master axes are the first axis, second axis, and third axis, and the slave axes
are the sixth axis, fifth axis, and fourth axis, set parameter No. 8311 as follows:
Parameter No.8311 X (first axis) = 0
Parameter No.8311 Y (second axis) = 0
Parameter No.8311 Z (third axis) = 0
Parameter No.8311 A (fourth axis) = 3
Parameter No.8311 B (fifth axis) = 2
Parameter No.8311 C (sixth axis) = 1
Example 2) One master axis can have multiple slave axes:
When the master axis is the first axis and the slave axes are the fourth axis, fifth axis,
and sixth axis, set parameter No. 8311 as follows:
Parameter No.8311 X (first axis) = 0
Parameter No.8311 Y (second axis) = 0
Parameter No.8311 Z (third axis) = 0
Parameter No.8311 U1 (fourth axis) = 1
Parameter No.8311 U2 (fifth axis) = 1
Parameter No.8311 U3 (sixth axis) = 1
