POINT
The home position shift function is used to compensate the home position stopped at with
machine home position return. If there is a physical limit to the home position, due to the relation
of the proximity dog installation position, use this function to compensate the home position to
an optimum position.
[Pr.55] Operation setting for incompletion of home position return
Set whether the positioning control is executed or not (When the home position return
request flag is ON.).
(1) When the home position return request flag is ON, selecting "0: Positioning control is not
executed" will result in the error "Start at home position return incomplete" (error code:
19A6H), and positioning control will not be performed. At this time, operation with the
manual control (JOG operation, inching operation, manual pulse generator operation) is
available.
The positioning control can be executed even if the home position return request flag is
ON when selecting "1: Positioning control is executed".
