Cam Axis Position Restoration Method

Cam axis position value per cycle restoration

If "[Pr.462] Cam axis position restoration object" is set to "0: Cam axis position value per cycle restoration" when starting
synchronous control, the cam axis position value per cycle is restored based on the cam reference position and the cam axis
command position value.
Select the method for the cam reference position to be restored. The command position value when starting synchronous
control is used as the cam axis command position value.
The cam axis position value per cycle is restored by searching for the corresponding value from the beginning to the end of
the cam pattern. Set the starting point from where to search the cam pattern in "[Pr.468] Cam axis position value per cycle
(Initial setting)". (It is also possible to search the return path in a two-way cam pattern operation.)
