Note:
1.
The Editor will not display “Circular Cyclic” as an option in the “CAM Type” field unless the
constraint described above is satisfied.
2.
For Cyclic CAMs, the master High/Low Position limits in Hardware Configuration must be set up
according to the master rollover points in the CAM profile. The master axis Low Limit must equal
the first master position in the profile. The master High Position Limit must be equal to the (Last
Master Position
–
1) in user units. This is because a cyclic profile's first and last point are the same
on the physical device. (for example, 0° and 360° on a circular knife).
3.
For a Circular Cyclic CAM, both the master axis and the slave axis rolls over at the profile's end
points. The High and Low position limits for the slave axis are set (in Hardware Config.) as follows:
−
If the minimum slave position is the profile's first point and the maximum slave position is
the last point, set the Low Position Limit to the first point's slave value and the High Position
limit to the (last point's slave value
–
1).
−
If the minimum slave position is the profile's last point and the maximum slave position is
the first point, set the Low Position Limit to the (last point's slave value + 1) and the High
Position Limit to the first point's slave value.
