for the main shaft.
Main input axis No.
Fetch cycle: At start of synchronous control
• Set the input axis No. on the sub input side
[Pr.401]
for the main shaft.
Sub input axis No.
Fetch cycle: At start of synchronous control

Fetch cycle: At start of synchronous control
Denominator
(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
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,
Setting details
(Note-1)
.............. 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
801 to 804 : Synchronous encoder
axis
Set in decimal.
0 : Invalid
1 to 16 : Servo input axis
801 to 804 : Synchronous encoder
axis
Set in hexadecimal.

.. 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)
When synchronous encoder axis is invalid, the input
value is always 0.
