tem is selected, the return-to-origin status is judged.

Axis:
0 means all axes, 1 means X axis, and 2 means Y axis. On dual-

On single-axis controllers, 0 and 1 alone can be specified.
(Example)
Transmission example 1:
Return-to-origin is executed to all axes.

If any axis of the mark system and axis of the search system are mixed, it is necessary
to previously complete the return-to-origin of the axis of the mark system in order to
execute the return-to-origin of the axis of the search system. The return-to-origin of
the mark system is executed with HPB.

If the return-to-origin is once executed after the robot cable is connected to the abso-
lute battery, it is unnecessary to execute it again even if the power supply is turned
off. (As an exceptional example, it is necessary to execute the return-to-origin again
since the origin is incomplete if the absolute back-up function is made to be invalid or
if any parameter concerned with the origin is changed.)
