Cam data starting point
This setting is only valid for cam data using the stroke ratio data format.
The cam data point corresponding to "Cam axis current value per cycle = 0" can be set as the cam data starting point.
The default value of the cam data starting point is 0. (The cam axis is controlled with cam data starting from the 0th point
(stroke ratio 0%).)
When a value other than 0 is set for the cam data starting point, cam control is started from the point where the stroke ratio is
not 0%.
The cam data starting point is set for each cam data. The setting range is from 0 to (cam resolution - 1).

■Stroke ratio data format
If "[Pr.440] Cam No." or "[Pr.441] Cam stroke amount" is changed during synchronous control, the new value is accepted and
applied when the cam axis current value per cycle passes through the 0th point of cam data, or is on the 0th point.
The cam reference position is updated when the cam axis current value per cycle passes through the 0th point of cam data.
■Coordinate data format
If "[Pr.440] Cam No." is changed during synchronous control, the new value is accepted and applied when the cam axis
current value per cycle passes through 0, or is on 0.
The cam reference position is updated when the cam axis current value per cycle passes through 0.
