Parameterization

4.12.2.1

Automatic selection of JOG retract after Power On

After the control has run up (Power On), the channels of a BAG are as standard in the
parameterized default mode:
MD10720 $MN_OPERATING_MODE_DEFAULT[<mode group>] = <default mode>
The following NC-specific machine data can be used to set which operating mode is selected
after the control run up, if there is retraction data in a BAG channel.
MD10721 $MN_OPERATING_MODE_EXTENDED[<mode group>] = <value>
Value
4.12.2.2

Enable of the traversing direction

The retraction movement can be limited to the positive direction of travel or enabled for both
travel directions using the following NC-specific machine data:
MD10735 $MN_JOG_MODE_MASK, Bit 8 = <Value>
Value
4.12.2.3

Measuring system status

The current status of the measuring system is displayed via the following axis-specific machine
data or must be set to the desired behavior for selection:
MD34210 $MA_ENC_REFP_STATE[<Axis>] = <Value>
Value
Absolute encoder
Incremental encoder
1) Only the values relevant for JOG-Retract are stated

Meaning
0 Selection of the operating mode corresponding to MD10720 $MN_OPERATING_MODE_DE‐
FAULT
1 Selection of JOG mode, if: DB21, ... DBX377.5 == 1 (retraction data available)
Meaning
0 Release: Positive traverse direction
1 Release: Positive and negative traverse 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
H1: Manual and handwheel travel
