Cam Axis Position Restoration Method

Cam axis current value per cycle restoration

If "[Pr.462] Cam axis position restoration object (R: D42742+160n/Q: D15102+150n)" is set to "0: Cam axis current value per
cycle restoration" when starting synchronous control, the cam axis current value per cycle is restored based on the cam
reference position and the cam axis current feed value.
Select the method for the cam reference position to be restored. The current feed value when starting synchronous control is
used as the cam axis current feed value.
The cam axis current value per cycle is restored by searching for the corresponding value from the beginning to the end of the
cam pattern. Set the starting point from where to search the cam pattern in "[Pr.468] Cam axis current value per cycle (Initial
setting) (R: D42752+160n, D42753+160n/Q: D15112+150n, D15113+150n)". (It is also possible to search the return path in a
two-way cam pattern operation.)

The cam axis current value per cycle is
restored based on the cam reference
position and cam axis current feed value.
