Positioning W/ Manual Data Input Operating Mode - HEIDENHAIN TNC 620 User Manual

Testing and running | Positioning w/ Manual Data Input operating mode
6.14 Positioning w/ Manual Data Input
operating mode
The Positioning w/ Manual Data Input operating mode is
particularly convenient for simple machining operations or for pre-
positioning the tool. It enables you to write a short NC program,
depending on machine parameter programInputMode (no. 101201),
in Klartext format or in ISO format and execute it immediately. The
NC program is stored in a file named $MDI.
You can use the following functions for example:
Cycles
Radius compensation
Program section repetitions
Q parameters
The additional status display can be activated in the Positioning w/
Manual Data Input operating mode.
Danger of collision!
Certain manual interactions cause the control to lose program
information affecting the mode and thereby to lose the so-called
contextual reference. After the loss of the contextual reference,
unexpected and undesired movements can occur. There is a
danger of collision during subsequent machining operations!
Do not perform the following interactions:
Cursor movement to another NC block
The jump command GOTO to another NC block
Editing an NC block
Modifying Q parameter values with the Q INFO soft key
Switching the operating modes
Restore the contextual reference via repetition of the required
NC blocks
