Starting method for synchronous control
Synchronous control can be started by turning the target axis bit from OFF to ON in "[Cd.380] Synchronous control start" after
setting the advanced synchronous control parameters.
"5: Analyzing" is set in "[Md.26] Axis operation status" at the synchronous control start, and the advanced synchronous control
parameters are analyzed. The BUSY signal turns ON after completion of analysis, and "15: Synchronous control" is set in
"[Md.26] Axis operation status".
Start the input axis operation after confirming that "15: Synchronous control" is set in "[Md.26] Axis operation status".
Ending method for synchronous control
Synchronous control can be ended by turning the target axis bit from ON to OFF in "[Cd.380] Synchronous control start" after
the input axis operation is stopped.
The BUSY signal turns OFF at the synchronous control end, and "0: Standby" is set in "[Md.26] Axis operation status" at the
output axis stop.
Synchronous control can also be ended by turning the target axis bit from ON to OFF in "[Cd.380] Synchronous control start"
during the input axis operation. However, it is recommended to end after stopping the input axis operation since the output
axis stops immediately.
Refer to the following for the stop operation of output axis at the synchronous control end.

Starting history
The starting history is updated when starting synchronous control. "9020: Synchronous control operation" is stored in "[Md.4]
Start No.".
Status at synchronous control start
The following bits in "[Md.31] Status" are turned OFF when starting synchronous control in the same way as for the positioning
control start.
