(2) Procedure for restarting synchronous control
1) Set the synchronous control initial position parameters for axis 2 and 3 as follows.
[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 bits for axes 2 and 3 in "[Cd.381] Synchronous control analysis
mode", and then turn ON the bits for axes 2 and 3 in "[Cd.380] Synchronous
control start" to execute the synchronous control analysis. The analyzed result is
updated in [Md.400] to [Md.425].
3) Position axes 2 and 3 to "[Md.409] Cam axis feed current value" which has been
updated in 2).
4) Turn OFF the bits for axes 2 and 3 in "[Cd.381] Synchronous control analysis
mode", and then turn ON the bits for axes 2 and 3 in "[Cd.380] Synchronous
control start" to start synchronous control.
