The key point number and its corresponding communication address can also be checked in the following
CANopen Builder software.
2. Suppose two cam curves are built in CANopoen Builder. There are 3 points for the first cam curve, 5
points for the second cam curve, and so there are totally 8 key points for the electronic cam curve
(the sum of the key points for the first cam curve plus the key points for the second cam curve). The
register parameter with serial no. 4 is the first point parameter of the second cam curve, for other
register parameters, the corresponding point of the second curve can be presumed in the same way
3. The revised key point parameter of electronic cam is effective immediately if “MC_ CamSet” is
executed first and then “MC_CamIn” is executed. Otherwise, The revised key point parameter of
electronic cam is ineffective till the old cam curve cycle is over

Curve 1 is changed into curve 1´ as above in process of running.
From curve 1, you can see three key points of e- cam with the serial no 1, 2, and 3 respectively
corresponding to the special D in the following table.
