[Pr.438] Cam axis cycle unit setting (R: D42698+160n/Q: D15058+150n)
Set the command units for the cam axis input per cycle to be used for cam control.
These units are used for setting the cam axis length per cycle and the cam axis current value per cycle.
There is no influence on the control for the parameter for monitor display. (Page 126 Units for the output axis)
[Pr.439] Cam axis length per cycle (R: D42700L+160n/Q: D15060L+150n)
Set the length per cycle of the cam axis to generate the cam axis current value per cycle.
The unit settings are in the cam axis cycle units. (Page 126 Cam axis cycle units)
Set a value within the range from 1 to 2147483647.
The cam axis length per cycle can be changed during synchronous control by setting "1: Valid" in "[Pr. 442] Cam axis length
per cycle change setting (R: D42699+160n/Q: D15059+150n)". When the cam axis current value per cycle passes through
the 0th point of cam data, or is at the 0th point of cam data, the value of "[Pr.439] Cam axis length per cycle (R: D42700+160n,
D42701+160n/Q: D15060+150n, D15061+150n)" is loaded.
For a cam using the coordinate data format, if the input value of the final coordinate is less than "[Pr.439] Cam axis length per
cycle (R: D42700+160n, D42701+160n/Q: D15060+150n, D15061+150n)", it is controlled using a line segment calculated
from the nearest two coordinates.
An example of a cam using coordinate data format, and changing "[Pr.439] Cam axis length per cycle (R: D42700+160n,
D42701+160n/Q: D15060+150n, D15061+150n)" to a value that exceeds the input value of cam data final coordinate during
synchronous control is shown below.

*1 Because the coordinate where "input value = cam axis length per cycle" does not exist, the final coordinate is calculated from the line
segment between the nearest two coordinates.
[Pr.440] Cam No. (R: D42702+160n/Q: D15062+150n)
Set the cam No. for cam control.
Cam No.0 is preset in the Motion CPU, and it operates as a linear cam for 100% of its stroke ratio along the cam axis length
per cycle.
The cam No. can be changed during synchronous control.
The value set in "[Pr.440] Cam No. (R: D42702+160n/Q: D15062+150n)" is valid when the cam axis current value per cycle
passes through the 0th point of cam data, or is on the 0th point.
