09.91 3 Operating Sequences
3.1.9 TRANSMIT coordinate transformation
Display of the TRANSMIT function:
In addition to the maximum of five real axes of the NC control, there are also two fictitious
axes for the TRANSMIT function, i.e. a total of up to seven axes. In the displays of the sub-
menus “Zero offsets (G54 to G59)”, “Scale modification”, “External zero offset”, “Setting
data axial” etc. this has been taken into account (input and display fields for the sixth and
seventh axes).
The machine manufacturer defines the designations of the fictitious and
real axes.
If, in any display, only the actual or other values for the first
five axes be shown, you can display the remaining two
axes after the keying sequence “Actual value with double
character height”, “page forwards”.
Sequence of operation
3.1.9.3 Monitoring the software limit switch for fictitious axes with the
TRANSMIT function
As in the case for real axes, fictitious axes, too, are checked for their position relative to the
software limit switches. During traversing in JOG mode the distance from the software limit
switch is loaded as the maximum axial distance-to-go. In “AUTOMATIC” mode the block final
points are checked for software limit switches and working area limitation only for the fictitious
axes of the transformation grouping. The real axes of the grouping are checked constantly for
software limit switch and working area limitation during axis motion.
The software limit switches set by the reduction area are not active for the fictitious axes. If the
radius axis is located outside the limits of the working area or the software limit switches, you
can move back in with transformation selected but you cannot move further out. You must
acknowledge the pending alarm message with a RESET. Acknowledgement of the alarm mes-
sage only functions, if the working area limitation and the software limit switches are no longer
active (i.e. you have moved the axes back into the normal working area in JOG or INC mode).
