For example: The master axis position is 100 and ActivationPosition 1000 at the time when the
MC_CamIn instruction execution starts. The master axis position is 1000 (1000= ActivationPosition)
as the actual engagement begins.

Stage 1: Trigger and execute the MC_CamIn instruction. The master axis absolute position is
100 at the moment.
Stage 2: Wait for the start of the engagement.
Stage 3: The master axis reaches the position for starting the engagement (1000) and the slave
axis starts to perform the engagement action.
Stage 4: The engagement is being conducted.
Stage 5: The engagement is completed and the master axis and slave axis achieve the
synchronization.
Stage 6: The master axis and slave axis are in the synchronous motion.

ActivationPosition: Absolute axis phase
When ActivationMode =2, ActivationPosition is an absolute axis phase which is the remainder got
by dividing the axis absolute position by modulo. The slave axis starts to perform the engagement
action as the master axis absolute phase is ActivationPosition.
The absolute axis phase is cyclic. Its absolute axis phase may be equal to ActivationPosition many
times in the motion of the master axis. But the slave axis starts to perform the engagement action
only when the absolute axis phase of the master axis is equal to ActivationPosition for the first time
after the MC_CamIn instruction is executed.
For example, the master axis modulo is 400, ActivationPosition=100 and the master axis position
is 1000 at the time when the MC_CamIn instruction is executed. The slave axis will not perform the
engagement action because the absolute axis phase of the master axis is 200 (200=1000%400) at
the time when the MC_CamIn instruction is executed. The slave axis starts to perform the
engagement action as the master axis position is 1300 (Absolute axis phase is 100=1300%400) or
900 (Absolute axis phase is 100=900%400). (% means the mathematic operation to find the
remainder)
