2. Difference from the type A
The type B (new type) is difference from the type A (old type) as follows. Therefore, matters
which are not described following should be regarded as “same to the type A”.
(1)
The type A and the type B are switched by the parameter No.8081#2 (TYB).
(2)
In the type A, because a end point of the cam shape data (displacement of the cam
follower that the cam shaft makes just one rotation) is equal to a start point, the end
point isn’t need to set. But in the type B, the end point must be set. Therefore, the
setting points as the cam shape data for the type B are one point more than the type A.
But both the type A and B, the maximum number of points which can be set are till
2,048.
Example 2-1)Amount of a shift per one rotation of a cam shaft is 360 degree. In a cam shape
data that a phase of 0 degree (start point) is equal to a phase of 360 degree (end
point), if the cam shape data is divided one rotation of cam shaft into 6 parts,
[Type A]
The displacement of the cam follower corresponding to the phase numbers of the cam
shaft 0-5 (
•
in the figure) are set as the cam shape data. The number of points of the cam
shape data is 6.

[Type B]
The displacement of the cam follower corresponding to the phase numbers of the cam

shape data is 7. This is one point more than the type A.
