TRACYL
TRACYL expansions:
The machine data below can be used to take the axial complete frame of the TRACYL rotary
axis, i.e., the translation, fine offset, mirroring and scaling, into account in the transformation:
MD24805 $MC_TRACYL_ROT_AX_FRAME_1 = 1
MD24855 $MC_TRACYL_ROT_AX_FRAME_2 = 1
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 or as a y offset. A c axis offset, as in the figure
above, then leads to corresponding x and y values.
MD24805 $MC_TRACYL_ROT_AX_FRAME_1 = 2
