DVP15MC11T Operation Manual
Stage 5: The engagement is completed and the master axis and slave axis achieve the
synchronization.
The engagement is completed and the slave axis and master axis achieve the cam
synchronization if the cam phase that the master axis and slave axis correspond to meets the
planned cam relationship after the slave axis starts to perform the engagement action.

NOTE: In the figure above, the set master axis position at the time when the engagement
begins is greater than the master position at the time when the MC_CamIn instruction
execution starts. The similar way is also applied to the circumstance that the set master axis
position at the time when the engagement begins is less than or equal to the master position at
the time when the MC_CamIn instruction execution starts.

ActivationPosition
The ActivationPosition parameter is the start position of the cam engagement, (which is the master
axis position). In other words, the slave axis starts to perform the engagement when the master axis
reaches the position specified by ActivationPosition after the MC_CamIn instruction is triggered and
executed.
ActivationPosition can be the master axis position, master axis phase, master axis cam phase,
which can be selected through the ActivationMode parameter.

ActivationPosition: Relative axis position
As ActivationMode=0, ActivationPosition is an axis position which is relative to the master axis
position at the time when the MC_CamIn instruction is executed. The master axis position as the
actual engagement starts is the value of ActivationPosition plus the master position of when the
MC_CamIn instruction execution begins.
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 1100 (1100=100+1000) 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 (1100) and the slave
axis starts to perform the engagement action.
Stage 4: The engagement is ongoing.
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 position
When ActivationMode =1, ActivationPosition is an axis position which is absolute to the master
axis position at the time when the MC_CamIn instruction is executed. The master axis position as
the actual engagement starts is ActivationPosition.
