2) When the linear encoder home position does not exist in the home position return direction
If the home position return is performed from the position where the linear encoder home position
does not exist in the home position return direction, an error may occur depending on the home
position return type. In this case, change the home position return type, or move the mover to the
stroke end on the opposite side of the home position return direction with the JOG operation from
the controller and others, and then perform a home position return.
