Example
The following shows an example of starting a cam pattern from the zero point of the cam axis position value per cycle with the
current command position value position as the origin when returning to a specified point, or home position return is
completed after a forced stop.
• Move to advanced synchronous control starting point
• Restore operation
Setting item Setting value
[Pr.439] Cam axis length per cycle 1000[pulse]
[Pr.441] Cam stroke amount 200[pulse]
[Pr.462] Cam axis position restoration object 2: Cam axis command position value restoration
[Pr.463] Setting method of cam reference position 2: Command position value
[Pr.464] Setting method of cam axis position value per cycle 1: Initial setting value of cam axis position value per cycle
[Pr.467] Cam reference position (Initial setting) None
[Pr.468] Cam axis position value per cycle (Initial setting) 0[pulse]

Move to the position of 150[pulse] by
return to cam starting position, or by home position return.

Operation starts from the position "Initial setting = 0[pulse]"
of the setting method of cam axis position value per cycle.
Start advanced synchronous control.
The cam reference position (command position value = 150[pulse])
becomes the equivalent for the position where
"Cam axis position value per cycle = 0[pulse]".
