INPUT AXIS MODULE
The settings for the parameter and monitor data for the input axis module that used with synchronous control are explained in
this chapter.
Refer to the following manual of the Simple Motion module that is used for details on the connection and control for the servo
amplifier and the synchronous encoder that 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 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 following manual of the Simple Motion module that is used for the controls other than the synchronous control.
User's Manual (Application)
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 following manual of the Simple Motion module that is used for details on virtual servo amplifier
function.
