M1: Kinematic transformation
7.2 TRACYL cylinder surface transformation (option)
Replaceable geometry axes
The PLC is informed when a geometry axis has been replaced using GEOAX( ) through the
optional output of an M code that can be set in machine data.
● MD22534 $MC_TRAFO_CHANGE_M_CODE
Number of the M code that is output at the VDI interface in the case of transformation
changeover.
Note
If this machine data is set to one of the values 0 to 6, 17, 30, then no M code is output.

Position of tool zero
The position of the tool zero point in relation to the origin of the Cartesian coordinate system
is specified by machine data as described in the following paragraph.
MD24820 TRACYL_BASE_TOOL_<t>
This machine data is used to inform the control of the tool zero point position in relation to the
origin of the cylinder coordinate system declared for TRACYL. The machine data has three
components for the axes X, Y, Z of the machine coordinate system.
