■Read/write data structure
Specify the following structures for Data1, Data2 of MCv_ReadProfileData/MCv_WriteProfileData.
• Data1
Specify the PROFILE_CAM_DATA type structure.
PROFILE_CAM_DATA
Interpolate Specifying

CycleLength Length per cycle
CycleMin Minimum value per
cycle
CycleMax Maximum value per
cycle
CycleTime Time per cycle
Stroke Stroke amount
NumberOfSections Number of sections
*2
Options Options
*1 It is not used in the cam data format (Specifying interpolation method is "0: Linear interpolation"). (It is ignored.)
*2 Specify "0".
• Data2
For MCv_ReadProfileData, a structure specified in Data2 differs depending on the Target. For MCv_WriteProfileData, it can
be executed despite the Target.
