(Note-1): The range from axis 1 to 2 is valid in the 2-axis module, from axis 1 to 4 is valid in the 4-axis module, from axis 1 to 8 is valid in the
8-axis module, and from axis 1 to 16 is valid in the 16-axis module.
[Pr.418] Auxiliary shaft axis No.
Set the input axis No. for the auxiliary shaft.
0: Invalid ....................................... The input value is always 0.
1 to 16: Servo input axis
801 to 804: Synchronous encoder axis
(Note-1): The range from axis 1 to 2 is valid in the 2-axis module, from axis 1 to 4 is valid in the 4-axis module,

.............. Set the synchronous encoder axis (axis 1 to axis 4).
from axis 1 to 8 is valid in the 8-axis module, and from axis 1 to 16 is valid in the 16-axis module.
Setting value
Set in decimal.
0 : Invalid
1 to 16 : Servo input axis

.. Set the servo input axis (axis 1 to axis 16). When the
servo input axis is not set in the system setting, the
input value is always 0.
If the number is set to the same value as the output axis,
the error "Outside auxiliary shaft axis No. range" (error
code: 720) occurs and synchronous control cannot be
started.
When synchronous encoder axis is invalid, the input
value is always 0.
