(1) Cam axis one cycle current value restoration
POINT
For the cam pattern of to-and-fro control, if no corresponding cam axis one cycle
current value is found, [AL. F6.1 Cam axis one cycle current value restoration
failed] will occur and cam control cannot be executed.
For the cam pattern of feed control, if no corresponding cam axis one cycle
current value is found, the cam standard position will automatically change and
the value will be searched again.
If the cam resolution of the cam used is large, search processing at cam control
switching may take a long time.
When CAMC (Cam control command) turns on, "Cam axis one cycle current value" is restored based on
"Cam standard position" and "Cam axis feed current value" and the control is switched to the cam
control. Set the "cam standard position" used for the restoration with cam control data. The feed current
value at cam control switching is used as "Cam axis feed current value".
The cam axis one cycle current value is restored by searching for a corresponding value from the
beginning to the end of the cam pattern.
Set the starting point for searching the cam pattern with "[Cam control data No. 7 Cam axis one cycle
current value (initial setting value)]". (It is also possible to search from the return path in the cam pattern
of to-and-fro control.)
Searching for the cam pattern
(It is also possible to search from a value in the
middle of the cam axis one cycle current value).
