Cam axis one cycle current value restoration
• 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 bit 5 of Control DI2 (2D02h) turns on, the control is switched to the cam control, restoring the "Cam axis current value
per cycle" based on the "Cam standard position" and the "Cam axis feed current value". 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".
To restore the cam axis current value per cycle, search for a corresponding value "Cam axis current value per cycle" 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 current value per cycle initial
setting value]". (It is also possible to search from the return path in the cam pattern of to-and-fro control.)
