3.1 MANUAL REFERENCE POSITION RETURN
The tool is returned to the reference position as follows :
The tool is moved in the direction specified in parameter ZMI (bit 5 of
No. 1006) for each axis with the reference position return switch on the
machine operator’s panel. The tool moves to the deceleration point at
the rapid traverse rate, then moves to the reference position at the FL
speed. The rapid traverse rate and FL speed are specified in parameters
(No. 1420,1421, and 1425).
Rapid traverse override is effective during rapid traverse.
When the tool has returned to the reference position, the reference
position return completion LED goes on.

Procedure for Manual Reference Position Return
Procedure
1 Press the reference position return switch, one of the mode
selection switches.
2 To decrease the feedrate, press a rapid traverse override switch.
When the tool has returned to the reference position, the reference
position return completion LED goes on.
3 Press the feed axis and direction selection switch corresponding to
the axis and direction for reference position return. Continue pressing
the switch until the tool returns to the reference position. The tool
moves to the deceleration point at the rapid traverse rate, then moves
to the reference position at the FL speed set in a parameter.
4 Perform the same operations for other axes, if necessary.
The above is an example. Refer to the appropriate manual provided by
the machine tool builder for the actual operations.
