Actual position capture
The control enables you to transfer the current tool position into the
program, for example during
Positioning-block programming
Cycle programming
To transfer the correct position values, proceed as follows:
Place the input box at the position in the block where you
want to insert a position value
Select the actual-position-capture function
In the soft-key row the control displays the axes
whose positions can be transferred.
Select the axis
The control writes the current position of the
selected axis into the active input box.
In the working plane the control always captures the
coordinates of the tool center, even though tool radius
compensation is active.
The control takes the active tool length compensation
into account and always captures the coordinate of the
tool tip in the tool axis.
The control keeps the soft-key row for axis selection
active until the actual position capture key is pressed
again. This behavior remains in effect even if you save
the current block or open a new block with a path
function key. If you have to choose an input alternative
via soft key (e.g. for radius compensation), then the
control closes the soft-key row for axis selection.
The actual-position-capture function is not allowed if
the Tilt working plane function is active.
