6. APPLICATION OF FUNCTIONS
6 - 14
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 one cycle current value
When the cam axis one cycle current value is in the middle of the specified stroke ratio data, the
intermediate value is calculated using 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
one cycle length" - Output value corresponding to "Input value = 0"
t
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 one cycle
length" that is equal to output value corresponding to "Input value = 0".

(Does not change because the output value is 0.)
