- Assigning suffixes to axis names
A suffix can be assigned to an axis name; examples are X1, X2, XM,
and XS. By assigning a suffix to the same axis name, those axes that
have the same axis name can be distinguished from each other when
displayed on the screen; in addition, when an axis-by-axis alarm is
issued, the axis in question can be identified.
Parameter No. 1021 is used to set a suffix.
Setting multiple slave axes
One master axis can have multiple slave axes.
Example:
In the example below, the X1 and X2 axes are synchronized with the
XM axis.

X1
3 88 1 1 Movement is made in
synchronization with
the XM axis.
X2
4 88 2 1 Movement is made in
synchronization with
the XM axis.
When multiple slave axes are involved, synchronous error
compensation, synchronization, synchronous error checking are
performed for each axis independently.
Combination with tandem control
Tandem control can be applied to both the master axis and slave axis.
The same axis arrangement restriction as that for normal tandem
control is applicable. There is no restriction specific to synchronous
control.
Axis selection for screen display
On a screen such as the current position display screen, a slave axis is
also displayed. The display for a slave axis can be disabled by setting
bit 6 (DSP) of parameter No. 1004 to 1 for the slave axis.
Axis selection in actual speed display
When bit 1 (SYN) of parameter No. 1817 is set to 1 to enable the use of
synchronous operation at all times, the slave axis is excluded from
calculation for actual speed display.
When bit 1 (SYN) of parameter No. 1817 is set to 0, a composite speed
involving the slave axis is displayed in the actual speed display. By
setting the axis selection signal for axis speed display *ACTFx to 1, the
slave axis can be excluded from calculation for actual speed display.
