INPUT AXIS MODULE
The settings for the parameter and monitor data for the input axis module that is used for synchronous control are explained in
this chapter.
Refer to the following manual for details on the connection and control for the servo amplifier and the synchronous encoder
that are used for input axis module.

Servo Input Axis
Overview of servo input axis
The servo input axis is used to drive the input axis based on the position of the servo motor controlled by the Motion module.
The status of a servo input axis can also be monitored even before the synchronous control start since the setting of a servo
input axis is valid after the system's power supply ON.
The following shows the relationship between the position of the servo motor and the servo input axis.

Control method for servo input axis
All controls (including synchronous control) can be executed for a servo input axis.
Refer to the following manual for the controls other than the synchronous control.
MELSEC iQ-R Motion Module User's Manual (Application for Simple Motion Mode)
If the virtual servo amplifier function is set in the servo input axis, synchronous control can be executed by the
input value as virtual.
Refer to "Virtual Servo Amplifier Function" in the following manual for details on virtual servo amplifier
function.
