In the Head Module window of MT Developer2, set the number of RWw/RWr points assigned to the
head module.
The number of points should be higher than the number of points set in the auto refresh setting, in the step
1 above. (Set the number of points whichever is greater between "Transfer to CPU" and "Transfer to
intelligent function module".)
If the number of points is going to be increased for a system extension or other reasons, set a large number of "RWw Link
Device" and "RWr Link Device" in the Head Module window of MT Developer2. Doing so will avoid changing the parameter
of the Motion controller at the system extension. However, increasing the number of the points lengthens the processing
time.
