If set to "101 to 116", the synchronous encoder axis control starts based on the high-speed input request [DI] for the specified
servo amplifier axis.
Set "4: High speed input request" in "[Pr.42] External command function selection" and set "1: Validates an external
command" in "[Cd.8] External command valid" for the specified servo amplifier axis to start from a high speed input request
[DI]. Also, set the external command signal to be used in "[Pr.95] External command signal selection".
Set the control method for the synchronous encoder axis in "[Cd.321] Synchronous encoder axis control method".
The Simple Motion module resets the value to "0" automatically after completion of the synchronous encoder axis control.

Details
The synchronous encoder axis current value and the synchronous encoder axis current value per cycle are changed as follows.
Set the new current value in "[Cd.322] Synchronous encoder axis current value setting address".

Input from the synchronous encoder is invalid. Smoothing processing, phase compensation processing and rotation direction
restriction processing are continued. While these processes are valid, the input axis speed may not stop immediately when the
counter disable is selected.
Input from the synchronous encoder is valid.
