The tool is returned to the reference position as follows :
The tool is moved in the direction specified in parameter (bit 0 to #3 of
No. 003) 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. 518
to 521, 533, and 534).
Fourstep 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. The tool generally moves along
only a single axis, but can move along three axes simultaneously when
specified so in parameter (bit 4 of No.049).

Procedure for Manual Reference Position Return
1 Press the reference position return switch, one of the mode selection
swithces.
2 To decerease 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 can be
moved along three axes simultaneously when specified so in an
appropriate parameter setting. 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.
