3) Cam data start position
This setting is available only for the stroke ratio data type cam data.
The cam data position where the "cam axis current value per cycle" becomes "0" can be set as
the cam data start position.
The initial value of the cam data start position is "0". The cam axis is controlled with the cam data
from the 0th point (stroke ratio = 0%).
When a value other than "0" is set as the cam data start position, cam control is started from the
point where the stroke ratio is not 0%.
Set the cam data start position for each cam data within the setting range of "0 to (Cam resolution
- 1)".
