Double-click the icon of a created cam table to open the key point editing page.
On the key point editing page, select master axis length and slave axis range based on the selected unit.
The master axis length is the travel distance of a master axis per cam cycle. The slave axis range indicates
the stroke of a slave axis for display of graphics and easy editing.
When the unit is millimeter, the master axis length ranges from 0 to 100,000 mm, and the slave axis ranges
from –100,000 to +100,000. When the unit is number of pulses, the master axis length ranges from 0 to
4,294,967,296, and the slave axis ranges from –2,147,483,648 to +2,147,483,647.
After the master axis length and slave axis range are set, you can set key points. As shown in the
