TITLE
(2),(3) can be applied to the application shown in the Fig.1-1.
Fig.1-1 Example applied enhancement (2)(3)
In the Fig.1-1, the horizontal axis corresponds to the phase of a CAM shaft and the vertical axis
corresponds to the position of each CAM follower. The external axis is performed to-and-fro linear
motion by the CAM shaft.
As shown in the Fig.1-1, the external axis is started from the certain point at first. Then the follower
axes #1, #2 and #3 are started one by one from the designated points. And electronic CAM operation
with an external axis as a CAM shaft (external synchronization) is performed.
When the operation is completed, the external axis will stop at the certain point and a CAM shaft is
switched to an imaginary axis at the same time so that the CAM follower axes stop at the certain point
smoothly. The imaginary axis starts moving automatically with keeping the velocity of the external axis.
Then electronic CAM operation with an imaginary axis as a CAM shaft (internal synchronization) is
performed.
After that, each follower axis will stop at each designated point one by one.
