— RAPID TRAVERSE
[Function]
Speed or feedrate of axis motion in "JOG" mode, "incremental feed" mode or "reference point
return" mode can be changed to rapid traverse speed.
[Operation]
When the signal (RT) is turned ON.
(1) The jog and incremental feedrate will be the rapid traverse feedrate set with parameters.
(2) The speed until the near-point detection dog signal is detected during dog-type reference point
return will be the reference point return rapid traverse feedrate set with parameters.
(3) Speed or feedrate is changed at the same time as the signal is turned ON.
When the signal (RT) is turned OFF, rapid traverse speed changes to the previous speed or
feedrate. "Feed axis select" signal (±J1~±J14) may be kept turned ON.
(4) The speed will be the rapid traverse feedrate until the near point dog signal is detected during
jog, incremental feed or reference point return. The rapid traverse override will also be valid.
(5) The "Rapid traverse override" (ROV1, ROV2) will be validated when the rapid traverse signal is
ON.

(Note 1) "Rapid traverse (RT)" signal does not act as mode signal, but serves as interrupt signal for
"JOG" mode, "INCREMENTAL FEED" mode, etc.
(Note 2) This signal can be used likewise during machine lock.
(Note 3) For handling of "Rapid traverse (RT)" signal during dry run, refer to the description about
dry run signal (DRN).
