Motion control concepts
Section 1-3

Additional to the standard move profiles the CJ1W-MCH72 also provides a
way to define a position profile for the axis to move. The
CAM
command
moves an axis according to position values stored in the CJ1W-MCH72 Table
array. The speed of travelling through the profile is determined by the axis
parameters of the axis.
The figure corresponds to the command
CAM(0,99,100,20)
. A is the time axis,
B is the position axis.

EG control
Electronic Gearing control allows you to create a direct gearbox link or a linked
move between two axes. The MC Unit supports the following operations.
• Electronic gearbox
• Linked CAM
• Linked move
• Adding axes
1-3-3-1 Electronic gearbox
The CJ1W-MCH72 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
CONNECT
command in the program. In the command the ratio and the axis to
link to are specified.
In the figure, A is the Master axis, and B is the
CONNECT
axis.
