Reference position return
A movement is made at the rapid traverse rate to the first reference position on a
specified axis. Upon completion of reference position return, the return completion
lamp is turned on.
Format
// ZDO ;
G91 G28 IP 0 ;
ZEND ;
G91 :G code for incremental command
IP 0 :Specify an axis on which reference position return is
to be performed.
Be sure to specify 0 as the travel distance.
NOTE
1. Only one axis can be specified in one block.
2. No intermediate point may be specified. (Be sure to specify 0 as the
travel distance. Otherwise, P/S alarm 410 is issued.) If a movement
needs to be once made to an intermediate point, specify positioning
with rapid traverse (G00)/machine coordinate system selection (G53)
then specify this command.
3. The absolute command (G90) cannot be specified.
4. When using this function, be sure to set bit 0 (RPD) of parameter No.
8002 to 0.
5. Before this command can be specified, a reference position must be
established. (With this command, do not specify an axis on which a
reference position is not established.)
6. Before specifying this command with the T series, cancel tool offset and
tool-nose radius compensation. Before specifying this command with
the M series, cancel cutter compensation, tool length compensation,
and tool offset.
・Rapid traverse override
With bit 2 (OVE) of parameter No. 8001, whether to use the rapid traverse
override signal for an NC statement or the rapid traverse override signal
dedicated to PMC axis control can be chosen.
NOTE
1. Even if bit 4 (RF0) of parameter No. 1401 is set to 1, rapid traverse
does not stop with a cutting feed override of 0%.
