■Change current value per cycle after auxiliary shaft gear
The current value per cycle after auxiliary shaft gear is changed to the value set in "[Cd.408] Synchronous control change
value (R: D42772+160n, D42773+160n/Q: D15132+10n, D15133+150n)".
This operation is completed within one operation cycle.
Clutch control is not executed if the current value per cycle after the auxiliary shaft gear (the value before being changed and
after being changed) has already passed through the ON/OFF address in address mode.
■Cam axis current value per cycle movement
This command is executed to move the cam axis current value per cycle through adding the setting travel value of "[Cd.408]
Synchronous control change value (R: D42772+160n, D42773+160n/Q: D15132+20n, D1533+150n)".
The travel value to be added is averaged in "[Cd.409] Synchronous control reflection time (R: D42771+160n/Q:
D15131+150n)" for its output.
Set a long reflection time when a large travel value is used since the cam axis current feed value moves with the travel value.

[Cd.407] Synchronous control change command
(R: D42770+160n/Q: D15130+150n)
When "[Rq.406] Control change request command (R: M42408+16n/Q: M11688+10n)" is reset to OFF while executing the
cam axis current value per cycle movement, operation is stopped midway. If the cam axis current value per cycle movement is
executed again, the remainder travel value is not reflected, and the operation starts with "[Cd.408] Synchronous control
change value (R: D42772+160n, D42773+160n/Q: D15132+150n, D15133+150n)" to be used again.
If synchronous control is stopped while the cam axis current value per cycle movement is being executed, operation also
stops midway. If synchronous control is restarted, the remainder travel value is not reflected.
[Cd.408] Synchronous control change value (R: D42772L+160n/Q: D15132L+150n)
Set the change value for synchronous control change processing as follows.
