This function can be used to change the cam reference position, the cam axis current
value per cycle and the current value per cycle after the main/auxiliary shaft gear
during the synchronous control.
The following 5 methods exist for the synchronous control change function.
Refer to Section 7.6.2 for details on each change command.

Setting details
Set the control change
command request command.
The complete signal of control
change request command
processing is stored
(1) [Rq.406] Control change request command (M11688+10n)
Set ON to initiate [Cd.407] Synchronous control change command
(D15130+150n). The [St.426] Control change complete (M10566+10n) turns ON
at the after completion of the synchronous control change.
This signal turns OFF at the synchronous control start.
(2) [St.426] Control change complete (M10566+10n)
This signal turns ON with the completion for control change.
If the control change processing is stopped midway, the signal remains to be
OFF.
Application
Change the cam axis current value per cycle.
Change the current value per cycle after main
shaft gear.
Change the current value per cycle after auxiliary
shaft gear.
Adjust the phase of the cam axis by travel value.
