How does SLAVE OFFSET work? How would an application benefit from using
slave offset?
The slave offset works similar to the CAM SHIFT. It uses an S-Curve profile to change
the offset from the current to the new absolute offset. The slave Offset is simply a value
added to the slave position after it’s position has been determined from the cam table. It is
the very last operation in the cam function.
The slave offset is useful when the slave must be adjusted at run time a uniform amount
across the entire cam profile. This can account for changes in material, temperature,
humidity etc.
