4. AUTOMATIC OPERATION
In cases such as when beam movement along an axis is stopped by feed
hold during automatic operation so that manual intervention can be used
to replace the nozzle: When automatic operation is restarted, this function
returns the nozzle to the position where manual intervention was started.
To use the conventional program restart function, the switches on the
operator’s panel must be used in conjunction with the MDI keys. This
function does not require such operations.
Before this function can be used, MIN (bit 0 of parameter No. 7001) must
be set to 1.
In manual absolute off mode, the nozzle does not return to the stop
position, but instead operates according to the manual absolute on/off
For the return operation, the dry run feedrate is used, and the jog feedrate
override function is enabled.
Return operation is performed according to positioning based on
If the single block stop switch is on during return operation, the nozzle
stops at the stop position and restarts movement when the cycle start
switch is pressed.
If a reset occurs or an alarm is issued during manual intervention or the
return operation, this function is cancelled.
This function can be used in the MDI mode as well.
This function is enabled only when the automatic operation hold LED is
on. When there is no travel distance remaining, this function has no effect
even if a feed hold stop is performed with the automatic operation hold
signal *SP (bit 5 of G008).
When the nozzle is replaced for a reason, the beam movement cannot be
restarted by a changed offset in the middle of the interrupted block.
When performing manual intervention, never use the machine lock,
mirror image, or scaling functions.
