Virtual axis VT
You can also carry out handwheel superimpositioning in the currently
active tool axis direction. You can use the Virtual Tool axis line (VT).
You can select the VT axis via the HR 420 handwheel in order to
traverse with superimpositioning in the virtual axis direction (see
“Selecting the axis to be moved” on page 502).
The TNC also shows the path traversed in the virtual axis in the
additional status display (POS tab) in the separate VT position display.
The TNC deactivates the value traversed in the virtual axis
direction as soon as you call a new tool.
You can only move with handwheel superimpositioning in
the virtual axis direction if DCM is inactive.
The TNC reduced the feed rate during superimposed rotary
axis movements depending on the maximum value
entered in the virtual axis VT. Otherwise, rapid traverse
could be exceeded when moving the rotary axes in the
linear axes X, Y or Z.
