CR#10000: Creating rotary cut electronic cam data
[Description]
DVP-20PM provides CR#10000 exclusively for creating rotary cut electronic cam. The user can create
and apply the rotary-cut electronic cam by setting up the related machinery parameters according to
actual needs. Parameters for rotary-cut electronic cam are as below.
Parameter Data Format Explanation
P1 Length of Master Integer
Length of the material feeding axis
Unit: mm
Length of Slave
Length of the cutting axis (cutter length included)
Unit: mm
P2
Sync start
position
Integer
When sync function is enabled, the register sets up the sync start
position.
Length of sync
area
Length of sync area
Unit: mm
P3
Sync end position
Integer
When sync function is enabled, the register sets up the sync end
position.
P4
Magnification
ratio
Floating
point
The speed of master and slave is synchonized in sync area.

Acceleration
curve
(Low word)
Integer
Electronic cam acceleration setting:
0: Uniform curve
1: Uniform acceleration curve
2: SingleHypot curve
3: Cycloid
Cam curve selection for different sections in sync area, e.g. start,
end:
0: leftCAM: Sync area is on the left side of cam curve
1: midCAMall
2: midCAMbegin
3: midCAMend (If the curve is selected, electronic cam stops
automatically when completed.)
5: rightCAM: Sync area is on the right side of cam curve.
Note: If 2 or 3 is selected, the length of the master axis will be 1/2
times the length of the slave axis.
P6
Cam curve
(High word)
Integer
Sync area setting
b[13]=1: Create sync area setting. When the function is enabled,
P2 and P3 should be filled with start and end position of sync
area.
b[14]=1: Changing data dynamically is not allowed.
b[15]=1: Borrow the data setting of previous electronic cam.
P7 Result Integer
Display the rotary cut electronic cam creating results (when read
back).
0: OK
1: Input data is not proper.
