Siemens SINUMERIK 840D sl Function Manual page 815

An axis can be simultaneously defined in MD20100 and in MD30460 (bit 2). For this, the
channel-specific MD20100 has a higher priority than the axis-specific MD30460.
With MD20100, during power up, the transverse axis:
● is assigned the function G96/G961/G962.
● is assigned the channel-specific diameter programming DIAMON, DIAMOF, DIAM90,
DIAMCYCOF.
After power up, this axis has the axis-specific basic position DIAMCHANA[<Axis>].
With MD30460 bit2, the additional enabling of the axis-specific operations DIAMONA[<Axis>],
DIAMOFA[<Axis>], DIAM90A[<Axis>], DIACYCOFA[<Axis>], DIMCHANA[<Axis>] takes
place.
Dimensions for tool parameters
According to MD20360 $MC_TOOL_PARAMETER_DEF_MASK, for all of the transverse axes
defined in the channel, the following tool parameters can be activated as diameter values:

Basic Functions
Function Manual, 01/2015, 6FC5397-0BP40-5BA2
Value Meaning
1 Transverse axis tool length as a diameter
1 Alarm for wear or tool length as a diameter and plane change
1 Work offset in frames of the transverse axis as a diameter
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.
1 Preset value as a diameter
1 External work offset of the transverse axis as a diameter
There is no conversion during a change of diameter, to radius programming or vice
versa.
1 Actual values of the transverse axis as a diameter
1 Display of actual values of the transverse axis as a diameter value
1 Tool portion of an active tool carrier that can be oriented if no tool is active
1 Evaluation of $TC_DP6 as a diameter
1 Evaluation of $TC_DP15 as wear of the tool diameter
1 Incremental values of the transverse axis for cycle masks as diameters
Value Meaning
0 Work offset $P_EXTFRAME and frames
For transverse axes, work offsets in frames are always calculated as radius values.
0 External work office (axis overlay)
For transverse axes, the external work offset is always calculated as a radius value.
