This feature allows the operator to interrupt program execution, jog away from the part, return to the interruption
point, and then resume program execution. The following is an operation procedure:
1. While a program is running, press FEED HOLD. This will stop all motion (after any canned cycle
in process has been completed.)
2. Press X, Y or Z followed by HANDLE JOG. The control will store the current XYZ positions. Note
that axes other than X, Y, and Z cannot be jogged.
3. The control will display JOG AWAY. The operator can jog (using the jog handle, remote jog
handle, jog and jog-lock buttons) to move the tool away from part, press AUX CLNT to cycle the
Through Spindle Coolant (TSC), press COOLNT to cycle the coolant stream, press CW, CCW,
STOP, TOOL RELEASE, the jog increment buttons and use the increment switch on the remote
jog handle. Note that AUX CLNT requires that the spindle be rotated and that the door be closed.
Tools can be swapped out and the associated length and diameter offsets adjusted, however, when
the program is continued, the old offsets will still be used for the return position and any motion
commands already in the queue. It is therefore unsafe to swap out tools and adjust offsets when
the program was interrupted during a cut.
4. Jog to a position as close as possible to the stored position, or to a position where there will be an
unobstructed rapid path back to the stored position.
5. Return to the previous mode by pressing MEM, MDI, or DNC. The control will only continue
normally if the mode that was in effect at the time of the interrupt is selected.
6. Press CYCLE START. The control will display the message JOG RETURN and rapid X and Y at
5% to the position when FEED HOLD was pressed, then the same for Z. The rapid rate override
keys have no effect during JOG RETURN. Caution: The control will not follow the path the operator
used to jog away. Instead, it will perform simple moves without regard for obstacles. Therefore, a
crash is possible. If FEED HOLD is pressed during this motion, the control will go into a feed hold
state and display the message JOG RETURN HOLD. Pressing CYCLE START will cause the
control to resume the JOG RETURN motion. When the motion is completed, the control will again
go into a feed hold state.
7. Press CYCLE START again and the program will resume normal operation.
