Resuming program run after an interruption
If you interrupt a program run during execution of a subprogram or
program section repeat, use the RESTORE POS AT function to return
to the position at which the program run was interrupted.
When a program run is interrupted, the TNC stores:
„ The data of the last defined tool
„
Active coordinate transformations (e.g. datum shift, rotation,
mirroring)
„
The coordinates of the circle center that was last defined
The stored data are used for returning the tool to the contour after
manual machine axis positioning during an interruption (RESTORE
POSITION soft key).
Resuming program run with the START button
You can resume program run by pressing the machine START button
if the program was interrupted in one of the following ways:
„ The machine STOP button was pressed.
„ An interruption was programmed.
Resuming program run after an error
If the error message is not blinking:
8 Remove the cause of the error.
8 To clear the error message from the screen, press the CE key.
8 Restart the program, or resume program run where it was
interrupted.
If there is a “processor check error”:
8 Switch to Manual mode,
8 Press the OFF soft key.
8 Remove the cause of the error.
8 Start again.
If you cannot correct the error, write down the error message and
contact your repair service agency.
If a program run is interrupted during a fixed cycle, the
program must be resumed from the beginning of the
cycle. This means that some machining operations will be
repeated.
Note that the stored data remain active until they are reset
(e.g. if you select a new program).
