from the engagement start wait state.
note:If ActivationPosition ActivationMode is 0 and is 0 (location relative to the shaft),
the current speed from the shaft will be moving toward the synchronous speed,
in addition, from immediately moving axis stops! The MC_CamIn instruction
input parameters at the moment is read and locked instruction, the instruction
for use during execution.

:Wait for the engagement start
From the shaft in a stationary state, waiting to begin execution timing of the
arrival of the engaging operation, i.e., after waiting for the spindle ActivationPosition
location specified parameters. From the waiting time axis will be different in different
circumstances, if the instruction to start execution MC_CamIn spindle
ActivationPosition i.e. at the location specified parameters, the slave axis starts
executing the engaging operation; never have a chance if the spindle reaches the
specified parameter ActivationPosition position, the slave axis will never be able to
begin engagement never be achieved cam synchronization. Parameters
ActivationPosition, ActivationMode role at this stage.

:Engaging the spindle reaches the start position, the shaft engagement operation
started
When the spindle passes ActivationPosition location specified parameters,
started from the shaft engagement operation. Parameters MasterAbsolute,
SlaveAbsolute, MasterOffset, SlaveOffset, MasterScaling, SlaveScaling onset of
action in the moment, for the correspondence relationship between the master axis
position of the shaft from the cam phase of its determination.

:During engagement
StartMode engagement operation performed by the parameter Slave axis in the
manner specified. In addition to the StartMode parameters, parameters Velocity,
Acceleration, Deceleration is also applied at this stage, they will determine the
meshing process, from the shaft speed, acceleration / deceleration motion
characteristics of these items.

:Complete engagement, the main shaft from the synchronization
After the engagement operation started from the shaft, the main shaft if the
corresponding cam phase satisfy the relationship of the cam planning,
completion of the engagement, to achieve synchronization of the cam shaft from
the spindle.
Description:The figure shows only the case when the engagement start position
of the spindle is greater than MC_CamIn instruction starts execution timing of the
main shaft position, and the case is equal to less than the same way may be derived.
 ActivationPosition
Start position parameter ActivationPosition cam engaged (the position of the spindle
"position"), i.e., the right trigger MC_CamIn instruction execution and the main shaft reaches
ActivationPosition, engagement operation started from the shaft.
ActivationPosition may be: the position of the spindle, the phase of the spindle, the spindle
cam phase parameter selected by ActivationMode.
