Retraction after a power interruption

The Retraction mode of operation must be enabled
and adapted by the machine tool builder. Refer to
your machine manual.
With the Retraction mode of operation you can disengage the tool
from the workpiece after an interruption in power.
The Retraction mode of operation is selectable in the following
conditions:
Power interruption
Relay external DC voltage missing
Traverse reference points
The Retraction operating mode offers the following modes of
traverse:
Mode
Machine axes
Tilted system
Tool axis
Thread
The tilted system mode of traverse is available only
when the "tilting the working plane" software option
is enabled on your TNC.
The TNC selects the mode of traverse and the associated
parameters automatically. If the traverse mode or the parameters
were not correctly chosen, you can change them manually.
