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 180 and in the actual execution, the corresponding slave axis
position is 240 (240=180+60).
Case 2
：
The master axis position corresponding to the slave axis position will shift (add) by 90
based on the planned position as
MasterScaling and SlaveScaling are 1, MasterOffset
is 90 and SlaveOffset is 0.
For example, in the planned cam relationship, the master axis position 180 corresponds
to the slave axis position 180 and in the actual execution, the master axis position 90
corresponds to the slave axis position 180 which is the slave axis position
corresponded to by the master axis position 180 (180=90+90) in the planned cam
relationship.

StartMode
In the engagement, the way how the slave axis moves is specified by the StartMode parameter. That is,
StartMode works at stage 4 in the execution of the MC_CamIn instruction as shown in the following figure.
Stage 1:
Trigger and execute the MC_CamIn instruction.
Stage 2: Wait for the start of the engagement.
