(b) Procedure for restarting synchronous control
1) Set the synchronous control initial position parameters for axis 2 and 3
as follows.
Setting item Setting value
[Pr.460] Setting method of current value per cycle after
main shaft gear (150n)
2: Calculate from input axis
[Pr.462] Cam axis position restoration object
(150n)
2: Cam axis current feed value
restoration
[Pr.463] Setting method of cam reference position
(150n)
0: Previous value
[Pr.464] Setting method of cam axis current value per cycle
(150n)
2: Current value per cycle after
main shaft gear
2) Turn ON the bit device for axes 2 and 3 in [Rq.381] Synchronous
analysis request (n), and then turn ON the bit device for axes 2
and 3 in [Rq.380] Synchronous control start (n) to execute the
synchronous control analysis. The analyzed result is updated in
Synchronous control monitor data ([Md.400] to [Md.402], [Md.406] to
[Md.411], [Md.422], [Md.425], [St.420], [St.421], [St.423], [St.424] (Refer
to Section 7.7)).
3) Position axes 2 and 3 to [Md.409] Cam axis current feed value
(30n, 30n) which has been updated in 2).
4) Turn OFF the bit device for axes 2 and 3 in [Rq.381] Synchronous
analysis request (n), and then turn ON the bit device for axes 2
and 3 in [Rq.380] Synchronous control start (n) to start
synchronous control.
