Ex.
Homing methods -11 and -43
The following figure shows the operation of Homing method -11. The operation of Homing method -43 is opposite to that of
Homing method -11.

Homing automatically starts from here.
*1 This cannot be used with the software limit.
• When the linear encoder home position does not exist in the homing direction
If the homing is performed from the position where the linear encoder home position does not exist in the homing direction, an
error may occur. 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.
