HEIDENHAIN ITNC 530 User Manual page 53

The TNC is now ready for operation in the Manual Operation mode.
The reference points need only be traversed if the
machine axes are to be moved. If you intend only to write,
edit or test programs, you can select the Programming
and Editing or Test Run modes of operation immediately
after switching on the control voltage.
You can traverse the reference points later by pressing
the PASS OVER REFERENCE soft key in the Manual
Operation mode.
Traversing the reference point in a tilted working plane
The reference point of a tilted coordinate system can be traversed by
pressing the machine axis direction buttons. The "tilting the working
plane" function must be active in the Manual Operation mode (see
"Activating manual tilting" on page 79). The TNC then interpolates the
corresponding axes.
Make sure that the angle values entered in the menu for
tilting the working plane match the actual angles of the
tilted axis.
If available, you can also traverse the axes in the direction of the
current tool axis (see "Setting the current tool-axis direction as the
active machining direction (FCL 2 function)" on page 80).
If you use this function, then for non-absolute encoders
you must confirm the positions of the rotary axes, which
the TNC displays in a pop-up window. The position
displayed is the last active position of the rotary axes
before switch-off.
If one of the two functions that were active before is active now, the
NC START button has no function. The TNC outputs a corresponding
error message.
