n: Axis No.-1
(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.400] Main input axis No., [Pr.401] Sub input axis No.
Set the main input axis No. and the sub input axis No. for the main shaft.
0: Invalid ....................................... The input value is always 0.
1 to 16: Servo input axis
(Note-1)
.. 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 following errors occur and synchronous control
cannot be started.
• Outside main input axis No. range (error code: 700)
• Outside sub input axis No. range (error code: 701)
801 to 804: Synchronous encoder axis
.............. Set the synchronous encoder axis (axis 1 to axis 4).
When synchronous encoder axis is invalid, the input
value is always 0.
(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.
