• When the linear encoder home position (reference mark) exists in the homing direction
Set one linear encoder home position in the full stroke, and set it in the proximity dog signal detection position.

• When the linear encoder home position does not exist in the homing direction
If homing is performed from a position where the linear encoder home position does not exist in the homing direction, an error
may occur depending on the homing method.
If an error occurs, change the homing method or temporarily move the servo motor to the stroke end opposite of homing with
the JOG operation or other methods from the controller, then perform homing.
