3.9 Retraction in the tool direction (JOG retract)
MD10721 $MN_OPERATING_MODE_EXTENDED[<mode group>] = <value>
Value Meaning
Enable of the traversing direction
The retraction can be limited to the positive direction of travel or enabled for both travel
directions:
MD10735 $MN_JOG_MODE_MASK, Bit 8
Value Meaning
Axial machine data
Measuring system status
The current status of the measuring system is displayed via the machine data, or must be
set in preparation for the required behavior:

0 Selection of the operating mode corresponding to MD10720
$MN_OPERATING_MODE_DEFAULT
1 Selection of JOG mode, if: DB21, ... DBX377.5 == 1 ("retraction data available")
0 Traversing enable: Only plus direction
1 Traversing enable: Plus and minus direction
Meaning
1)
2 Encoder is calibrated
1 Automatic referencing: Enabled, but encoder still not referenced
2 Automatic referencing: Encoder is referenced and in exact stop, automatic referencing takes
effect at next time encoder activation
3 Restoration of the actual position: The last axis position buffered before switching off is
restored, no automatic referencing
