[Pr.440] Cam No.
Set the cam No. for cam control.
Cam No.0 is preset in the Simple Motion module, 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." 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
Set the cam stroke amount corresponding to a 100% stroke ratio in output axis position units (Page 91 Units for the
output axis) for cam control using the stroke ratio data format.
The cam stroke amount can be changed during synchronous control.
The value set in "[Pr.441] Cam stroke amount" 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.
[Pr.442] Cam axis length per cycle change setting
Set to change the cam axis length per cycle during synchronous control.
It can be changed for cam control using the cam No.0 (linear cam), the stroke ratio data format, and the coordinate data
format. However, it cannot be changed when the cam data whose starting point is other than 0 is used for the stroke ratio data
format.
Setting value
0: Invalid
0: Valid
[Pr.444] Cam axis phase compensation advance time
Set the time to advance or delay the phase of the cam axis current value per cycle in the cam control.
Setting value
1 to 2147483647 [s]
0 [s]
-2147483648 to -1 [s]
If the setting time is too long, the system experiences overshoot or undershoot at acceleration/deceleration of the input speed.
In this case, set a longer time to affect the phase compensation amount in "[Pr.445] Cam axis phase compensation time
constant".

Details
The cam axis length per cycle cannot be changed during synchronous control.
The value set in "[Pr.439] Cam axis length per cycle" is valid when the cam axis current value per cycle passes through
the 0th point of cam data, or is on the 0th point.
Details
Advance the phase according to the setting time.
Do not execute phase compensation.
Delay the phase according to the setting time.
