Setting value Details
0: Invalid The input value is always 0.
1 to 16: Servo input axis
*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 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)
201 to 208: Command generation axis
*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.
801 to 816: Synchronous encoder axis
*1
Set the synchronous encoder axis (axis 1 to 16). When the synchronous encoder axis is invalid, the input value is
always 0.
