3.1.9 TRANSMIT coordinate transformation

“PRESET” mode:

The actual value for a fictitious axis can only be set while the transformation (G131) is select-
ed. It only makes sense to use the function if the transformation remain active after a RESET.
A PRESET offset with @435 is possible for fictitious axes, independent of those for real axes
(see Part 2, “Programming”, Section 11.7).
The actual value memory and therefore also the actual value display refer to the machine zero
“M” after reference point approach. The offset entered in “PRESET” mode is calculated into
the actual value and displayed.
Independent of the value for the 1st real axis during TRANSMIT (radius axis) the origin of the
fictitious coordinate system coincides with the machine zero when the transformation is
selected (PRESET offset is not taken into account).

Monitoring of the programmed feedrate does not function correctly for

input of PRESET offsets for fictitious axes.

“TEACH IN”/“PLAYBACK” mode:

“TEACH IN” is a block program mode and is therefore also possible in the TRANSMIT
function.
There are two applications of the “PLAYBACK” mode:

– If the transformation is deselected (G130), only real axis positions are transferred

into the part program.

– If the transformation is selected (G131), axis positions of the real (not belonging to

the grouping) or of the fictitious axes can be transferred into the part program.

Special cases:

– “DRF/handwheel” active

The transformation must be selected before “DRF/handwheel” can be activated for the fictitio-
us system. Otherwise no handwheels must be enabled for the real axes of the transformation
grouping.

– Follow-up mode

During follow-up mode for real axes, the values for the fictitious axes are not prepared. Data
preparation in the NC begins with the changeover of the axes from follow-up mode to closed-
loop control.
