Check the machine reference.
After return-to-origin (absolute search on semi-absolute type axes) is complete, the
machine reference on each axis is displayed. Check that the machine reference is
within the allowable range.

NOTE
• Refer to "11.8.1 Return-to-origin operation" for details on return-to-origin
operation, and refer to "11.8.2 Semi-absolute" for details on absolute search
operation.
• The machine reference is expressed as a percentage of the number of encoder
pulses showing the difference between the origin sensor signal and position
detector reference signal (encoder zero signal, etc.). This is also called the "grid
position" or "grid pulse".

Check the message line display.
When return-to-origin on all axes is complete, the dashed line (- - - -) on the message
line changes to a solid line (––––) indicating that return-to-origin is now complete. Then,
pressing an axis movement key displays the current position on each axis.
When origin incomplete status cannot be cancelled, this means that absolute type
axes exist and absolute reset has not yet been completed on those axes. Perform
absolute reset on those axes.

NOTE
Once return-to-origin is completed, the origin position is retained until the controller
power is turned off or system parameters are changed. So it is not necessary to
re-perform return-to-origin even after using emergency stop.
