14. USING A LINEAR SERVO MOTOR
(b) 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 does not exist in
the home position return direction, a home position return error occurs on the controller. The error
contents differ according to the controller type. Move the linear servo motor 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.
