[St.323] Synchronous encoder axis current value setting request flag (R: M38643+16n/
Q: M10443+10n)
This flag turns ON, when a synchronous encoder axis current value change is never executed or when the synchronous
encoder current value is lost by the battery error, etc. in the serial absolute synchronous encoder.
If the current value setting request flag is ON for the synchronous encoder connection, the synchronous encoder axis current
value starts counting with 0.
This flag turns OFF when a synchronous encoder axis current value change is executed.
For a system that needs alignment of synchronous encoder, confirm that "[St.323] Synchronous encoder axis
current value setting request flag (R: M38643+16n/Q: M10443+10n)" is OFF.
[St.324] Synchronous encoder axis error detection flag (R: M38644+16n/Q:
M10444+10n)
• This signal turns ON with detection of a warning or error of synchronous encoder axis, and can be used to judge whether
there is a warning or error or not. The applicable warning code is stored in the "[Md.327] Synchronous encoder axis
warning code (R: D38570+32n/Q: M13250+20n)" with detection of a warning. The applicable error code is stored in the
"[Md.326] Synchronous encoder axis error code (R: D38571+32n/Q: M13251+20n)" with detection of an error.
• This signal turns off when the "[Rq.323] Synchronous encoder axis error reset (R: M42240+8n/Q: M11600+4n)" turns on.
Refer to the following for the warning codes and error codes with detection of warning and errors.

[St.325] Synchronous encoder axis control complete flag (R: M38646+16n/Q:
M10446+10n)
This flag turns ON at the completion of synchronous encoder axis control.
This flag turns OFF when "[Rq.320] Synchronous encoder axis control request (R: M42241+8n/Q: M11601+4n)" is turned ON
to OFF.
