8 AUXILIARY AND APPLIED FUNCTIONS
(1) Example
The following shows an example of aligning the synchronous position of an
output axis that references the input axis.
1) Set the following values in the synchronous control initial position
parameters.
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 target axis bit of [Rq.381] Synchronous analysis request
(n), and then turn from OFF to ON in [Rq.380] Synchronous control
start (n) to start the synchronous control analysis mode.
3) Verify that [St.381] Synchronous analysis complete (n) is OFF, and
execute positioning for the output axis to be updated to [Md.409] Cam axis
current feed value (30n,30n).
4) Turn OFF [Rq.381] Synchronous analysis request (n), and then turn
from OFF to ON [Rq.380] Synchronous control start (n) to start
synchronous control.
