St.381 Synchronous • The bit device turns ON
analysis when the synchronous
complete control analysis is
completed.
• The bit device turns OFF
when [Rq.380]
Synchronous control start
(R: M43440+n/Q:
M12000+n) turns OFF to
ON.
Starting method for synchronous control
Synchronous control can be started by turning "[Rq.380] Synchronous control start (R: M43440+n/Q: M12000+n)" from OFF
to ON after setting the parameters for synchronous control.
"[St.1040] Start accept flag (R: M30080+n/Q: M2001+n)" turns ON at the synchronous control start, and the parameters for
synchronous control are analyzed. "[St.380] Synchronous control (R: M40000+n/Q: M10880+n)" turns ON after completion of
analysis, and the synchronous control starts.
Start the input axis operation after confirming that "[St.380] Synchronous control (R: M40000+n/Q: M10880+n)" of the output
axis turns ON.
When "[St.381] Synchronous analysis complete (R: M40080+n/Q: M10912+n)" is ON at the synchronous
control start, "[St.381] Synchronous analysis complete (R: M40080+n/Q: M10912+n)" turns OFF by turning
"[Rq.380] Synchronous control start (R: M43440+n/Q: M12000+n)" OFF to ON. However, "[St.381]
Synchronous analysis complete (R: M40080+n/Q: M10912+n)" does not turn ON by the analysis completion
at the synchronous control start. ("[St.381] Synchronous analysis complete (R: M40080+n/Q: M10912+n)"
turns ON by the analysis completion at the synchronous control analysis mode start.)
Ending method for synchronous control
Synchronous control can be ended by turning "[Rq.380] Synchronous control start (R: M43440+n/Q: M12000+n)" from ON to
OFF after the input axis operation is stopped.
"[St.380] Synchronous control (R: M40000+n/Q: M10880+n)" turns OFF at the synchronous control end, and the "[St.1040]
Start accept flag (R: M30080+n/Q: M2001+n)" turns OFF at the output axis stop.
Synchronous control can also be ended by turning "[Rq.380] Synchronous control start (R: M43440+n/Q: M12000+n)" from
ON to OFF during the input axis operation. However, it is recommended to end the synchronous control after stopping the
input axis operation since the output axis stops immediately.
Refer to Stop Operation of Output Axis for the stop operation of output axis at the synchronous control end.(Page 25 Stop

[Md.1008] Execute program No. (R: D32012+48n/Q: D12+20n)
This register stores the starting program No. at the servo program starting.
"FFEF" is stored in the "[Md.1008] Execute program No. (R: D32012+48n/Q: D12+20n)" when starting advanced synchronous
control.
