FEED AXIS SELECT (+)
—
nTH AXIS
[Function]
This signal is used to start motion (jog feed, incremental feed or reference point return mode) in
plus direction during manual operation.
These signals are for each control axis, and the number at the end of the signal name indicates the
control axis No.
+Jn
1 : 1st axis is selected for feed motion
2 : 2nd axis is selected for feed motion

14 : 14th axis is selected for feed motion
+ ... Feed motion in + direction
- ... Feed motion in - direction
[Operation]
When feed axis select signal (+Jn) turns ON, the following motion occurs.
(1) When jog feed, incremental feed or reference point return is possible, motion in plus direction
occurs on the selected axis.
(2) In jog feed, motion continues while the signal is ON.
Jog mode(J)
Feed axis select (+J1)
1st axis motion [+]
(3) In incremental feed, amount (length) of motion depends on setting of "Handle/incremental feed
multiplication". The motion is in plus direction. Even when signal (+Jn) turns OFF during motion,
the motion (feed) does not stop. To start the motion again, turn ON the signal after the
preceding motion has been completed.
Incremental feed mode (S)
Feed axis select (+J1)
1st axis motion [+]
(4) After reference point return mode is decelerated to approach speed by the near point detect
dog, the motion continues, even after the feed axis select signal is turned OFF, until motion
reaches the reference point.
