[Classification] Input signal
[Function] Notifies the control unit of synchronous, independent, or normal
operation selected under synchronization control or twin table
control.
Under synchronization control, these signals are valid only when
SYN (bit 1 of parameter No. 1817) is set to 0.
[Operation] Control is applied according to the combination of SYNCm and
SYNCs, as listed below.
Here, m indicates the axis number of the master axis while s indicates
the axis number of a slave axis.

*1 Under synchronization control or for manual operation under twin
table control, SYNCm may be set to "1" or "0."
*2 The settings for master axis independent operation are exactly the
same as those for normal operation.
*3 Under synchronization control or in manual operation under twin
table control, independent operation is not supported.
