3: Sudden stop (Stop by remaining move distance clear)
As in the following parameter settings, when the home
position is lost by the forward rotation stroke end, reverse
rotation stroke end, or the software limit detection, the
home position return completion (ZP) turns on by turning
OFF/ON the servo-on (SON). In this case, there is no
need to perform the home position return again.
