Notes on setting parameters for each axis
Parameters to be set for each axis can be divided into the following three types when they are
set for an axis under twin-table control:
1) Parameter which must be set to the same value for the master and slave axes
2) Parameter which may be set to different values for the master and slave axes
3) Parameter which needs to be set only for the slave axis (data for the master axis is not
used.)
Parameters are listed for each type below. If a parameter is not listed in any table below,
assume that the parameter is of type 1) and set the same value for the master and slave axes.
CAUTION
If different values are set in a parameter of type 1) for the master and
slave axes, these axes may not operate as synchronization mode.
1) Parameter which must be set to the same value for the master and slave axes
