n Resuming program run after an interruption
When a program run is interrupted, the TNC stores:
n
The data of the last defined tool
n Active coordinate transformations (e.g. datum shift, rotation,
mirroring)
n 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:
n
The machine STOP button was pressed.
n
An interruption was programmed.
Resuming program run after an error
If the error message is not blinking:
U U U U Remove the cause of the error.
U U U U To clear the error message from the screen, press the CE key.
U U U U Restart the program, or resume program run where it was
interrupted.
If the error message is blinking:
U U U U Press and hold the END key for two seconds. This induces a TNC
system restart.
U U U U Remove the cause of the error.
U U U U 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.
If you interrupt a program run during execution of a
subprogram or program section repeat, use the RESTORE
POS AT N function to return to the position at which the
program run was interrupted.
Note that the stored data remains active until it is reset
(e.g. if you select a new program).
