When Automatic stop mode is selected the machine automatically
stops when the workpiece has been cut through.
For normal cutting, Automatic stop function is recommended.
Automatic Stop Explained
The automatic stop function is based on monitoring the electrical
current used by the cut-off wheel motor. For automatic stop to
function properly, two criteria have to be met:
•
The current used at the start of a cutting operation has to
exceed a minimum value. If it does not, Automatic stop will not
be enabled.
•
The current used during the cutting operation has to remain
above a minimum value. When it falls beneath this value, cutting
will stop.
In some samples, for example tubes, the current may fall beneath
the minimum value when the wall of the tube has been cut through
and the centre (hollow part) of the tube is reached during the cutting
operation. If this happens, cutting will stop even though the sample
has not been fully cut through.
When automatic stop is enabled during a cutting operation, this is
indicated by a graph icon beside the Auto stop bar graph (see,
below).
Automatic Stop
Note:
When cutting tubes or other none solid samples, Automatic stop is not
recommended. Use either Relative or Absolute stop instead.
