A gradual stop occurs if a mode other than the jog feed mode is selected
or the feed axis direction command signal (+X or -X) is turned off
during reference position return. Reference position return must start at
a point sufficiently away from a deceleration area and must be
performed in the direction toward the reference position. The
deceleration area is as shown below.

1 If the direct command interface is used, select the
AUTO mode and input 60H as function code, then
invert the EBUF signal. Then, the machine movable

return operation.

machine is always positioned by rapid traverse at
the reference position.
