CR#10002: E-CAM Chart Real-time Change
[Explanations]
There are 3 built-in E-CAM charts in PMSoft: E-CAM Chart-0~E-CAM Chart-2. If you need to conduct real-time
change of E-CAM chart during program execution, set up this register to designate the E-CAM chart to be enable
in the next cycle. Care should be taken on the number of E-CAM charts, which should be as least 2 sets available
for the change. The instruction below is the application example. Set D0 = K10002 before the E-CAM Chart real
time change. When X0 = ON, set value (0, 1, 2) in D100 indicating the CAM Chart to be selected (E-CAM
Chart-0~E-CAM Chart-2) will be written into DVP-PM.

CR#10003:
Smooth Curve Interpolation
[Explanations]
When the original data points are not sufficient for a smoother operation, you can apply Smooth Curve
Interpolation. The detailed content of smooth curve interpolation will be explained in 9.4.2.2. Parameters for
setting up the function are listed as below.
Parameters Data Format Explanations
P1 Length of Master Integer Length of master can be modified
according to actual needs.
Original data points
Integer Data points before interpolation
P2
Total points to be inserted Integer Number of points to be equally
inserted into the sections between
original points.
Smoothing coefficient Integer Times of smoothing curve operation
3: 3 times
4: 4 times
5: 5 times
6: 6 times
Other: 3 times
P3
Cycloid types Integer 0: Uniform B-Spline
1: Non Uniform B Spline
2: C-spline (original data points
should be less than 20 points)
3: CC Spline
4: Cycloid
