Function
After a program interruption in automatic mode (e.g. to take a
measurement on the workpiece or to compensate tool wear values or
after tool breakage), you can retract the tool manually from the
contour after selecting "Jog" mode. In such cases, the control stores
the coordinates of the point of interruption and displays the path
distances traversed by the axes in "Jog" mode as a "Repos" offset
(Repos = repositioning) in the actual value window.
"Repos" offsets can be displayed in the machine coordinate system
(MCS) or workpiece coordinate system (WCS).
Operating sequence
"Jog" mode is selected in the "Machine" operating area.
The axes have been moved away from the point of interruption.
Select machine function "Repos".
Turning machine:
Press the "Axis" keys.
Milling machine:
Select the axis to be traversed and
press the "+" or "–" key.
It is not possible to pass over the point of interruption.
The feedrate override switch is active.
Warning
The rapid traverse override switch is active.
Non-adjusted Repos offsets are adjusted on switchover to Automatic
mode followed by start with program advance and linear interpolation.
