[Pr.460] Setting method of current value per cycle after main shaft gear
[Pr.462] Cam axis position restoration object
[Pr.463] Setting method of cam reference position
[Pr.464] Setting method of cam axis current value per cycle
2.
Turn ON the target axis bit of "[Cd.381] Synchronous control analysis mode", and then turn the target axis bit from OFF
to ON in "[Cd.380] Synchronous control start" to start the synchronous control analysis mode.
3.
