1) Feed current value
The feed current value of the cam axis is calculated as follows:
Feed current value = Cam standard po Output value 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.
One resolution or between
two coordinates
Cam axis
one cycle current value
Cam data
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 Output value corresponding to "Input value = Cam axis
length per cycle" - Output value corresponding to "Input value = 0"
t

Cam standard
position
(First cycle)
Output value corresponding to
"Input value = Cam axis one cycle length"
- Output value corresponding to "Input value = 0"
Cam standard
position
(Second cycle)
Feed current value
Cam axis
one cycle current value
Cam standard
position (Third cycle)
For to-and-fro control, use the output value corresponding to "Input value = Cam axis length per
cycle" that is equal to output value corresponding to "Input value = 0".
