This parameter specifies the servo axis number for spindle control by servo
motor and servo-spindle synchronous control.
If setting value is ‘0’, these functions are invalid.
It is necessary to set parameter No.2016#4(SPSx) to use the servo-spindle
synchronous control function.

Please set the number of the spindle (position coder) for servo-spindle
synchronous control. Please set the path number in the place of ten and set the
number of the position coder in each path in the place of one.
For instance, when the servo axis in the second path and the second position
coder in the first path are synchronized, set ‘12’ in this parameter in the second
path in two path system controls.
When the place of ten is 0, it is the same meaning as the specification of my own
path. When both the place of one and the place of ten are 0, it is the same
meaning as the specification of the first position coder in my own path.
Warning
The combination of synchronizing position coder and servo motor is decided by
connecting of the motor and the amplifier. Therefore, the combination of the
position coder and the servo motor which synchronizes cannot be changed even if
the setting value of this parameter is changed.
This parameter is used to accelerate or to decelerate when it is on/is turned off the
synchronous mode. Please set the value as the de-and acceleration is not correctly
done when a value different from the combination by connecting wires is set, it is
dangerous, and connected wires without fail it.
