(3) Cam axis position at synchronous control start
The cam axis position is composed of the relationship of 3 positions "Cam axis
current value per cycle", "Cam reference position" and "Cam axis current feed
value". One of positions can be restored by defining 2 positions when starting
synchronous control.
Cam axis current feed value
Cam reference position
Cam axis current value per cycle
Select from 3 objects as follows in [Pr.462] Cam axis position restoration object
(150n) which position is to be restored.
(Refer to Section 8.6 for details on the restoration method.)
1) Cam axis current value per cycle restoration
2) Cam reference position restoration
3) Cam axis current feed value restoration
Various parameters need to be set for the cam axis position restoration as shown
in Table 8.2. (Refer to Section 8.5 for the setting details.)
