Detailed Description
2.2 Dimensional information for transverse axes
Permanently radius-related data
For transverse axes, the following data is always entered, programmed and displayed in
relation to radius:
• Offsets:
• Working area limitation
• software limit switch
• Feed
• Display data with reference to the machine coordinate system
• Display data of the service images for axis, FSD and MSD
Extended functions for data that is always radius-related:
• PLC axes, via FC18 or axes controlled exclusively by the PLC.
Radius programming from MD20100 $MC_DIAMETER_AX_DEF and
MD30460 $MA_BASE_FUNCTION_MASK, bit2 is dependent upon
MD20360 $MC_TOOL_PARAMETER_DEF_MASK taken into consideration as follows:
bit3=0: Work offset $P_EXTFRAME and frames
For transverse axes, work offsets in frames are always calculated as radius values.
Bit5=0: external work offset (axis superimposition)
For transverse axes, the external work offset is always calculated as radius values.
Bit8=1: Display of remaining path in WCS always as a radius
DRF-traveling with handwheel
For all transverse axes, MD11346 $MN_HANDWH_TRUE_DISTANCE == 1 for
bit9=0:
causes the half path of the specified handwheel increment to be traveled, if channel-specific
or axis-specific diameter programming is active for this axis.
Bit 9=1:
the half path of the specified handwheel increment is always traveled.

– Tool offsets
– Programmable and configurable frames
– External work offset
– DRF and preset offset
– etc.
– The dimension for PLC axes in the radius also applies to several transverse axes with
diameter function and is independent of channel-specific or axis-specific diameter
programming.
– In JOG mode (Inc) a PLC axis is subordinate to the channel status. If diameter
programming is active and MD20624 $MC_HANDWH_CHAN_STOP_COND bit15=0,
only half the path of the specified increment is transversed.
