■Read/write data structure
Specify the following structures for Data1 of MCv_ReadProfileData/MCv_WriteProfileData. However, when reading the cam
data opened by using the cam data for the rotary cutter from the open area again, it becomes the cam data format. Therefore,
use a read/write data structure of the cam data format. For details, refer to the following.

Description
Set the resolution for generating the cam. (2 to 32768)

Specify "0".
• Bit 0: Acceleration/deceleration method
0: Trapezoidal acceleration/deceleration
1: S-curve acceleration/deceleration
• Bit 1: Synchronous axis length setting
0: Diameter
1: Cycle length
• Set "0" for bit 2 to 15.
Set the number of cutter. (1 to 256)
• Set when the synchronous speed in the synchronous section needs to be
adjusted.
• The speed is "Synchronous speed  (100% + Acceleration ratio)" in the
synchronous section.
(-50.0 to 50.0)
Set the sheet length. (0 < SheetLength < The positive positioning range)
• Set the sheet synchronization width (seal width).
• When the synchronous speed section for retracting operation is required in
front of and behind the sheet synchronization width, add the retracting
width.
(0 < SheetSyncWidth < SheetLength)
(0 < SheetSyncWidth < Cycle length /NumberOfCutter)
• Set the rotary cutter axis length.
• When the auto-generation option is set to the diameter, it is calculated as
"Cycle length = setting value   ".
• When the auto-generation option is set to the cycle length, it is calculated
as "Cycle length = setting value".
(0 < Cycle length < The positive positioning range)
• Set the position adjustment of the synchronous section.
Negative value: The synchronous section is adjusted to the sheet start
side.
0: The center of the sheet is in the synchronous section.
Positive value: The synchronous section is adjusted to the sheet end side.
(The absolute value of SyncPositionAdjustment < SheetLength / 2)
• Set the sheet width (one side) of the acceleration/deceleration area.
• When a negative value is set, the acceleration/deceleration width is
calculated to be the maximum.
(2  AccDecWidth  SheetLength - SheetSyncWidth)
When the auto-generation is successfully completed, the asynchronous
speed is stored as the ratio of the synchronous speed.
