The display for mode 5 differs from that of the other modes in that an
additional input field is provided at the right of the mode identification

Program I Enter the number of a traversing (machining) program in this field for
modes 8, 9 and 10.

specification for an absolute or relative positioning operation, a zero
offset or a tool offset.
Override I The speed for a positioning operation can be modified by entering an
override factor in this field (for modes 1 to 7). The positioning speed can
also be altered during traversing. The override factor must be forwarded
to the IP with <F6>.
