We also need to indicate to Axis #2, the rollover points for the Master axis position reference. To
do this, select the Axis #2 tab in hardware configuration. Input 49,999 into the High Position Limit
and 0 into the Low Position Limit data entry fields (Figure 16-36). Note that since this is a Cyclic
CAM, the master source high limit, by definition, must be one less than the last point in the master
data table. In our example this is point 50,000. Thus, the high limit is equal to 49,999. One way to
envision this principle is to think of a Cyclic CAM Master as a continuous circular strip where the
first point on the strip is the same as the last point on the strip. Thus, for our example, 50,000 is the
same point as zero. While in this tab, change the Home Mode: to Move + and OverTravel Switch to
Disabled.
