Siemens 810T manual Sequence of operation, Display of the Transmit function

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 ªZero offsets (G54 to G59)º, ªScale modificationº, ªExternal zero offsetº, ªSetting data axialº 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.

Sequence of operation

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 ªActual value with double character heightº, ªpage forwardsº.

3.1.9.3Monitoring 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 ªAUTOMATICº 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of the alarm mes- sage only functions, if the working area limitation and the software limit switches are no longer active (i.e. you have moved the axes back into the normal working area in JOG or INC mode).
