(b) Coordinate data type
The following are set in the coordinate data type. Set these in the cam setting window of MR
Configurator2. When "Cam No." is set to "0", straight-line control is performed so that the stroke ratio
at the last point of the cam data becomes 100%.
Setting item Setting Setting range
Cam No.
Set a Cam No. 0: Linear cam
1 to 8: User-created cam
Setting method Set "2: Coordinate data type".
Number of coordinate
Set the number of coordinates for the cam curve of one cycle.
The number of coordinates includes 0th point. 2 to 1024
Cam data start position Setting is not necessary.
Coordinate data
Set the coordinate data (input value Xn and output value Yn) for the
number of coordinates.
Set from the 0th coordinate data (X0 and Y0).
Set an input value larger than that of the coordinate data. -999.999 to 999.999
The following is a setting example for the coordinate data type.
