Replaceable geometry axes
When the GEOAX() geometry axes are switched, the parameterized M function is output to
the NC/PLC interface:
● MD22534 $MC_TRAFO_CHANGE_M_CODE = <M function>
Note
The values 0 to 6, 17 and 30 are not output.

Programming

The front face transformation (TRANSMIT) is activated in the part program or synchronized
action using the TRANSMIT statement.
Syntax
TRANSMIT
TRANSMIT(<n>)
Meaning
TRANSMIT:
TRANSMIT(n):
Note
A TRANSMIT transformation active in the channel is activated with:
● Deactivate transformation: TRAFOOF
● Activation of another transformation: E.g. TRACYL, TRAANG, TRAORI

Constraints

Look Ahead
All functions requiring Look Ahead (traversal through pole, Look Ahead) work satisfactorily
only if the relevant axis motions can be calculated exactly in advance. With TRANSMIT, this
applies to the rotary axis and the linear axis perpendicular to it. If one of these axes is the
positioning axis, then the Look Ahead function is deactivated by alarm 10912 and the
conventional online velocity check activated instead.
