[Pr.400] • Set the input axis No. on the main input
Main input axis side for the main shaft.
No. Fetch cycle: At operation start (Synchronous
control)
[Pr.401] • Set the input axis No. on the sub input side
Sub input axis No. for the main shaft.
Fetch cycle: At operation start (Synchronous
control)
[Pr.402] • Select the composite method for input
Composite main values from the main input axis and sub
shaft gear input axis.
Fetch cycle: Operation cycle
[Pr.403] • Set the numerator for the main shaft gear.
Main shaft gear: Fetch cycle: At operation start (Synchronous
Numerator control)
[Pr.404] • Set the denominator for the main shaft
Main shaft gear: gear.

*1 The range 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.
*2 The range from axis 1 to 4 is valid in the 4-axis module and from axis 1 to 8 is valid in the 8/16-axis module.

Details
The input value is always 0.
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 No. 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: 1E30H)
• Outside sub input axis No. range (error code: 1E31H)
*2
Set the command generation axis (axis 1 to 8). When the command generation axis is invalid in the parameter
setting, the input value is always 0.
*1
Set the synchronous encoder axis (axis 1 to 16). When the synchronous encoder axis is invalid, the input value is
always 0.
