■Cam reference position movement
This command is executed to move the cam reference position through adding the setting movement amount of "[Cd.408]
Synchronous control change value". The movement amount to be added is averaged in "[Cd.409] Synchronous control
reflection time" for its output. Set a long reflection time when a large movement amount is used since the cam axis feed
current value moves with the movement amount.

change command
When "[Cd.406] Synchronous control change request" is reset to "0" while executing the cam reference position movement
instruction, operation is stopped midway. If the cam reference position movement instruction is executed again, the remainder
movement amount 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 instruction is being executed, operation also
stops midway. If synchronous control is restarted, the remainder movement amount 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". 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.
