Homing operation
Precautions
• To execute homing securely, move the linear servo motor to the opposite stroke end with the JOG operation from the
controller or by other means, then start homing.
• Change the setting value of [Pr. PL01.2 Homing stop interval setting] in accordance with the linear encoder resolution.
■Incremental linear encoder
• When the linear encoder home position (reference mark) exists in the homing direction
The position obtained by moving the home position shift distance from the linear encoder home position (reference mark) is
set as the home position.
Ex.
Homing methods 33 and 34
The following figure shows the operation of Homing method 34. The operation of Homing method 33 is opposite to that of
Homing method 34.
