9-1 Performing Return-to-Origin
There are two methods for detecting the origin position (reference point): search method and mark
method. The search method is further divided into the origin sensor method and stroke-end detection
method. In the mark method, you can move the robot to a desired position (mark position) and set it
as the particular coordinate position to determine a reference point.
The following sections explain how to perform return-to-origin by using the search method and mark
method.
Once return-to-origin is performed after the robot cable and absolute battery are connected, there is
no need to repeat it even when the controller is turned off. (As an exception, return-to-origin becomes
incomplete if the absolute backup function is disabled or a parameter relating to the origin is changed.
Return-to-origin must be reperformed in that case.)
