[Pr.439] Cam axis length per cycle (D15060+150n, D15061+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 114 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 (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 (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 (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 (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. (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. (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.
[Pr.441] Cam stroke amount (D15064+150n, D15065+150n)
Set the cam stroke amount corresponding to a 100% stroke ratio in output axis position units for cam control using the stroke
ratio data format. (Page 114 Output axis position units)
The cam stroke amount can be changed during synchronous control.
The value set in "[Pr.441] Cam stroke amount (D15064+150n, D15065+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.
The setting value is ignored for a cam using the coordinate data format.
