Displaying position values in the diameter
Position values of the transverse axis are always displayed as a diameter value, if the bit0=1
is set by
MD27100 $MC_ABSBLOCK_FUNCTION_MASK.
Dimension on several transverse axes permanent diameter-related data
Several transverse axes permitted by MD30460 $MA_BASE_FUNCTION_MASK, bit2=1 do
not behave differently in comparison to a transverse axis defined using MD20100
$MC_DIAMETER_AX_DEF. Diameter values continue to be converted into radius values.
For all of the transverse axes defined in the channel, the following functions can be activated
as a diameter per MD20360 $MC_TOOL_PARAMETER_DEF_MASK for a set bit:
1: Transverse axis tool length as a diameter
2: Alarm for wear or tool length as a diameter and level change
3: Work offset in frames of the transverse axis as a diameter
4: Preset value as a diameter
5: External work offset of transverse as a diameter
6: Actual values of the transverse axis as a diameter
7: Display of actual values of the transverse axis as a diameter value.
10: Tool portion of an active tool carrier that can be oriented if no tool is active
11: Evaluation of $TC_DP6 as a diameter
12: Evaluation of $TC_DP15 as wear of the tool diameter
Work offset $P_EXTFRAME and frames
Bit3=1: For all transverse axes
, work offsets in frames are always calculated as diameter values. The frame stores the work
offsets internally as a radius value. There is no conversion during a change of diameter, to
radius programming or vice versa.
Work offset external
Bit 5=1: For all transverse axes,
external work offsets are always calculated as diameter values. There is no conversion
during a change of diameter, to radius programming or vice versa. Radiusprogrammierung

Settable response of geometry axes for traveling with handwheel
If the geometry axis is traveled as a transverse axis in the channel for handwheel traveling
MD11346 $MN_HANDWH_TRUE_DISTANCE == 1, the response of the handwheel traveling
can be changed via MD20624 $MC_HANDWH_CHAN_STOP_COND, bit15:
Bit15=0: Only the half path of the specified increment is traveled.
Bit15=1: The specified increment is traveled completely.
