1) Feed current value
The feed current value of the cam axis is calculated as follows:
Feed current value = Cam standard po (Cam stroke amount × Stroke ratio to cam axis
current value per cycle)
When the cam axis current value per cycle is in the middle of the specified stroke ratio data, the
intermediate value is calculated from the cam data before and after the value.
Cam axis
one cycle current value
Cam data
One resolution or between
two coordinates
An intermediate value is calculated using the
data before and after the value.
2) Cam standard position
The cam standard position is calculated as follows:
Cam standard position = The preceding cam standard po (Cam stroke amount × Stroke
ratio at the last point)

Cam stroke amount × Stroke ratio at the last point
For to-and-fro control, create the cam data in which the stroke ratio at the last point is 0%.
