Next to the standard CAM profiling tool the CJ1W-MCH72 also provides a tool
to link the CAM profile to another axis. The command to create the link is
called CAMBOX. The travelling speed through the profile is not determined by
the axis parameters of the axis but by the position of the linked axis. This is
like connecting two axes through a cam.
In the figure, A is the Master axis (0) position, and B is the CAMBOX Axis (1)
position.

The MOVELINK command provides a way to link a specified move to a
master axis. The move is divided into an acceleration, deceleration and
constant speed part and they are specified in master link distances. This can
be particularly useful for synchronizing two axes for a fixed period.
The labels in the figure are:
A Time axis.
B Speed axis.
C Master axis (1).
D Synchronized.
E MOVELINK axis (0).
