Via servo amplifier
■Setting method
The device connected to the servo amplifier is used as the synchronous encoder axis.
The following shows a list of devices that can be connected as a synchronous encoder axis depending on the type of servo
amplifier used.

Setting "101: Via servo amplifier" in "[Pr.320] Synchronous encoder axis type" and "ABS" or "INC" in the "External
synchronous encoder input" of amplifier setting enables the serial absolute synchronous encoder connected to the specified
servo amplifier axis to be used.
When a servo amplifier axis with a serial absolute synchronous encoder or ABS scale installed is connected, the synchronous
encoder axis connection becomes valid. The synchronous encoder axis current value and the synchronous encoder axis
current value per cycle are restored, and the synchronous encoder axis connection is on the counter enabling status. When a
servo amplifier axis with an incremental scale installed is connected, the synchronous encoder axis connection becomes
valid. "0" is set to the initial value of the synchronous encoder axis current value and the synchronous encoder axis current
value per cycle, and the synchronous encoder axis connection is on the counter enabling status. When the applicable servo
amplifier axis is not connected, the synchronous encoder axis connection is invalid.
For servo amplifiers performing "Via servo amplifier", use the software version that supports each encoder connected. The
software version that supports each encoder is shown in the table below.
―: There is no restriction by the version.
