Algorithm
Similar to gearing, in a camming application, a slave axis can perform any
move when camming is enabled. The move profile is superimposed over
the camming profile.

Camming Device
The device can be one of the following:
• an axis
• an encoder
• an analog sensor
The slave axis now moves in
proportion to the master device.
