8 AUXILIARY AND APPLIED FUNCTIONS
(d) If the cam resolution is large, search processing may take a long time when
starting synchronous control. (Cam resolution 32768: up to about 23ms)
(2) Cam axis current value per cycle restoration operation
(a) With a two-way cam pattern operation
1) Search from "Cam axis current value per cycle = 0".
(Cam data starting point = 0)
Cam axis current feed value
(Current feed value)
Search from "Cam axis
current value per cycle=0".
Restore to the first current feed
value that matches.
(Other values are not restored.)
Cam axis current value per cycle
Cam reference position
2) Search from a value in the middle of the cam axis current value per
cycle. (Cam data starting point = 0)
Cam axis current value per cycle
Cam axis current feed value
(Current feed value)
Cam reference position
Restore to the first current value
that matches. (The restoration is
done on the second.)
[Pr.468] Cam axis current value per cycle
(Initial setting)
(150n, 150n)
Search from the value in the
middle. (Preceding values are
searched later.)
3) Search from a value in the middle of the cam axis current value per
cycle. (Cam data starting point ≠ 0)
Cam axis current value per cycle
Cam axis current feed value
(Current feed value)
Cam reference position
[Pr.468] Cam axis current value per cycle
(Initial setting)
(150n, 150n)
Restore to the first current
feed value that matches.
Cam data
starting point
Search from the value
in the middle.
