Electronic Gearbox
The MC Unit is able to have a gearbox link from one axis to another as if there
is a physical gearbox connecting them. This can be done using the CON-
NECT command in the program. In the command the ratio and the axis to link
to are specified.
Linked CAM control
Next to the standard CAM profiling tool the MC Unit 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.
Linked Move
The MOVELINK command provides a way to link a specified move to a mas-
ter axis. The move is divided into an acceleration, deceleration and constant
