Transmit expansions:

The machine data

MD24905 $MC_TRANSMIT_ROT_AX_FRAME_1 = 1

MD24905 $MC_TRANSMIT_ROT_AX_FRAME_2 = 1

can be used to take the axial complete frame of the transmit rotary axis, i.e., the translation,

fine offset, mirroring and scaling, into account in the transformation.

A rotary axis offset can, for example, be entered by compensating the oblique position of a

workpiece in a frame within a frame chain. As a rule, this offset can also be included in the

transformation as an offset in the rotary axis. A c axis offset, as in the figure above, then

leads to corresponding x and y values.

MD24905 $MC_TRANSMIT_ROT_AX_FRAME_1 = 2

MD24905 $MC_TRANSMIT_ROT_AX_FRAME_2 = 2

With this setting, the axial offset of the rotary axis is taken account of in the transformation

up to the SZS. The axial offsets of the rotary axis included in the SZS frames are entered

into the transformation frame as rotations. This setting is only effective if the transformation

frame has been configured.
