2 STARTING UP THE SYSTEM
(3) Starting method for synchronous control
Synchronous control can be started by turning [Rq.380] Synchronous control
start (M12000+n) from OFF to ON after setting the parameters for synchronous
control.
Start accept flag (M2001+n) turns ON at the synchronous control start, and the
parameters for synchronous control are analyzed. [St.380] Synchronous control
start (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
start (M10880+n) of the output axis turns ON.
POINT
When [St.381] Synchronous analysis complete (M10912+n) is ON at the
synchronous control start, [St.381] Synchronous analysis complete (M10912+n)
turns OFF by turning [Rq.380] Synchronous control start (M12000+n) OFF to ON.
However, [St.381] Synchronous analysis complete (M10912+n) does not turn ON
by the analysis completion at the synchronous control start. ([St.381] Synchronous
analysis complete (M10912+n) turns ON by the analysis completion at the
synchronous control analysis mode start.)
(4) Ending method for synchronous control
Synchronous control can be ended by turning [Rq.380] Synchronous control start
(M12000+n) from ON to OFF after the input axis operation is stopped.
[St.380] Synchronous control start (M10880+n) turns OFF at the synchronous
control end, and the start accept flag (M2001+n) turns OFF at the output axis
stop.
Synchronous control can also be ended by turning [Rq.380] Synchronous control
start (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 "Section 2.3" for the stop operation of output axis at the synchronous
control end.
(5) Execute program No. storage device (D12+20n)
This register stores the starting program No. at the servo program starting.
"FFEF" is stored in the execute program No. storage device (D12+20n) when
starting advanced synchronous control.
