■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%.

Cam axis one cycle length [Cam axis cycle unit]
If "input value = 0" and "input value = cam axis length per cycle" are not set in the coordinate data, a control is executed by the
line created from the closest two points.

Setting
Set a Cam No.
Set "2: Coordinate data type".
Set the number of coordinates for the cam curve of one cycle.
The number of coordinates includes 0th point.
Setting is not necessary.
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.
