■Cam reference position movement
This command is executed to move the cam reference position through adding the setting travel value of "[Cd.408]
Synchronous control change value (R: D42772+160n, D42773+160n/Q: D15132+150n, D15133+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.

Q: D13616+30n, D13617+30n)

[Rq.406] Control change request command

[St.426] Control change complete
(R: M38966+16n/Q: M10566+10n)
[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 reference position movement command, operation is stopped midway. If the cam reference position movement
command 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 reference position movement command is being executed, operation also
stops midway. If synchronous control is restarted, the remainder travel value is not reflected.
■Change cam axis current value per cycle
The cam axis current value per cycle is changed to "[Cd.408] Synchronous control change value (R: D42772+160n,
D42773+160n/Q: D15132+150n, D15133+150n)". The cam reference position will be also changed to correspond to the
changed cam axis current value per cycle.
This operation is completed within one operation cycle.
[Md.407] Cam axis current value per cycle
(R: D39132+32n, D39133+32n/

Q: D13616+30n, D13617+30n)

[Md.408] Cam reference position
(R: D39134+32n, D39135+32n/
Q: D13614+30n, D13615+30n)
[Rq.406] Control change request command
(R: M42408+16n/Q: M11688+10n)
[St.426] Control change complete
(R: M38966+16n/Q: M10566+10n)
[Cd.407] Synchronous control change command
(R: D42770+160n/Q: D15130+150n)
■Change current value per cycle after main shaft gear
The current value per cycle after main shaft gear is changed to the value set in "[Cd.408] Synchronous control change value
(R: D42772+160n, D42773+160n/Q: D15132+150n, D15133+150n)". This operation is completed within one operation cycle.
Clutch control is not executed if the current value per cycle after main shaft gear (the value before being changed and after
being changed) has already passed through the ON/OFF address in address mode.
