(2) Cam data
POINT
If the cam data is set incorrectly, the position command and speed command
may increase and may cause machine interference or [AL. 31 Overspeed].
When you have created and changed cam data, make sure to perform test
operations and make appropriate adjustments.
The following two types are available for the cam data.
Cam data type
Description
Stroke ratio data type
Cam curve of one cycle is divided equally by the number of cam resolution and defined.
The cam curve will be created according to the stroke ratio data of the number of cam resolution.
Coordinate data type
Data in which cam curve of one cycle is defined with two or more points. The coordinate data is
defined as (input value, output value). The input value will be the cam axis current value per cycle,
and the output value will be the stroke value from the cam standard position.
(a) Stroke ratio data type
The following are set in the stroke ratio 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 range
Cam No.
Set a Cam No.
0: Linear cam
1 to 8: User-created cam
Setting method
Set "1: Stroke ratio data type".
Cam resolution
Set the number of divisions for the cam curve of one cycle.

256/512/1024/2048.
Cam data start position
Set the positions of the cam data and cam control data to the position of
when "Cam axis current value per cycle" is "0".
0 to "Cam resolution - 1"
Stroke ratio data
Set the stroke ratio from the first to the last point.
-100.000 to 100.000
The following is a setting example for "cam resolution = 512" in the stroke ratio data type.
