Case 1： The actual cam relationship is consistent with the preplanned one as the values of
MasterScaling and SlaveScaling are 1 and their offsets are 0.
Case 2： The slave position corresponding to the master axis position is two times what is
planned in the cam relationship as the value of MasterScaling is 1, SlaveScaling is 2
and their offsets are 0.
Case 3： The slave position corresponding to the master axis position is 1/2 that in the planned
cam relationship as the value of MasterScaling is 1, SlaveScaling is 0.5 and their
offsets are 0.
Case 4： The master axis position corresponding to the slave axis position is 1/2 what is
planned as the value of MasterScaling is 0.5, SlaveScaling is 1 and their offsets are 0.
If it is observed from the perspective of the cam phase, the master axis cam phase is
1/2 what is preplanned. That is, the master cam cycle changes from 360 to 180
(180=360*0.5) and the slave axis cam phase is unchanged.
Case 5： The master axis position corresponding to the slave axis position is 2 times what is
planned as the value of MasterScaling is 2, SlaveScaling is 1 and their offsets are 0. If
it is observed from the perspective of the cam phase, the master axis cam phase is
two times the original. That is, the master axis cam cycle changes from 360 to 720
(720=360*2) and the slave axis cam phase is unchanged.
 MasterScaling:1 and SlaveScaling:1 and the impact of MasterOffset and SlaveOffset on
the actually executed cam relationship
MasterOffset means to make the actual axis position curve shifted horizontally in execution
of the cam motion. SlaveOffset indicates to make the axis position curve shifted vertically in
execution of the cam motion.
Case 1： The slave axis position corresponding to the master axis position will add by 60 based
on the planned position as MasterScaling and SlaveScaling are both 1, MasterOffset is
0 and SlaveOffset is 60.
For example, in the planned cam relationship, the master axis position 180
corresponds to the slave axis position 120 and in the actual execution, the
