Chapter 2 Input Axis Module
2.1 Servo input axis
2.1.1 Overview of servo input axis
The servo input axis is used to drive the input axis based on the position of the servomotor
that is being controlled by the Simple 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 servomotor 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 "User's Manual (Positioning Control)" of each Simple Motion module for the
controls other than the synchronous control.
POINT
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 the "User's Manual (Positioning Control)" of each Simple Motion module for
details on virtual servo amplifier function.
