[Cd.406] Synchronous control change request
Set "1" to initiate "[Cd.407] Synchronous control change command". The Simple Motion
module resets the value to "0" automatically after completion of the synchronous control
change.
The setting is initialized to "0" when starting synchronous control.
[Cd.407] Synchronous control change command
Set the synchronous control change command.
0: Cam reference position movement ................................................ (1)
1: Change cam axis current value per cycle ..................................... (2)
2: Change current value per cycle after main shaft gear .................. (3)
3: Change current value per cycle after auxiliary shaft gear ............. (4)
4: Cam axis current value per cycle movement ................................ (5)
(1) 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". The travel value
to be added is averaged in "[Cd.409] Synchronous control reflection time" for its
output.
Set a long reflection time when a large travel value is used since the cam axis feed
current value moves with the travel value.

change command
When "[Cd.406] Synchronous control change request" is reset to "0" 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" 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.
