Cam axis position at synchronous control start
The cam axis position is composed of the relationship of 3 positions "Cam axis position value per cycle", "Cam reference
position" and "Cam axis command position value". One of positions can be restored by defining 2 positions when starting
synchronous control.
Select from 3 objects as follows in "[Pr.462] Cam axis position restoration object" which position is to be restored.
(Refer to Page 147 Cam Axis Position Restoration Method for details on the restoration method.)
• Cam axis position value per cycle restoration
• Cam reference position restoration
• Cam axis command position value restoration
Various parameters need to be set for the cam axis position restoration as shown below. (Refer to Page 144
Synchronous Control Initial Position Parameters for the setting details.)
