9. MANUFACTURER FUNCTIONS
(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
Cam No.
Setting method
Number of coordinate
Cam data start position
Coordinate data
The following is a setting example for the coordinate data type.
Output value: Y
[Output axis position unit]
999.999
(Cam standard position) (X
-999.999
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.
Output value: Y
[Output axis position unit]
999.999
(Cam standard position)
-999.999
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.
