8311 Axis number of master axis in synchronous control
[Data type] Byte axis
[Valid data range] 0 to 3
Select a master axis and slave axis for simple synchronous control. Set
a master axis number for the slave axis side. A maximum of two pairs can
be synchronized.
Example1: When using the first axis (X–axis) as the master axis, and the
third axis (Z–axis) as the slave 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) = 1
Parameter No. 8311 A (fourth axis) = 0
Example2: If there are two master/slave axis pairs under simple
synchronous control:
To specify the:
master axis as the 1st axis, and the slave axis as the 4th axis
master axis as the 2nd axis, and the slave axis as the 3rd axis,
set the following:
Parameter No. 8311 X(1st axis) = 0
Y(2nd axis) = 0
Z (3rd axis) = 2
(4th axis) = 1
Specifying the third axis (Z–axis) as the master axis, and the first axis
(X–axis) as the slave axis is not allowed. The master axis number must
always be smaller than the slave axis number.
It is impossible to specify more than one slave axis for a master axis.
NOTE
In Example 2 above, the Z axis, which is the master axis of
the M Series, is used as the slave axis of another axis. This
usage may prevent other functions from operating normally.
When exercising simple synchronous control with two pairs,
take care.
Limit of the difference between the amount of positioning deviation of the master
and slave axes (one master/slave axis pair under synchronous control)

[Data type] Word
[Unit of data] Detection unit
[Valid data range] 0 to 32767
This parameter specifies a limit imposed on the positional deviation
difference between the master and slave axes. If the limit is exceeded, a
P/S alarm (No. 213) is issued.
