6.4 Status-window
The status of the control (axis positions, tools, feed, M-functions etc.) is displayed on the VDU-screen in
the status window. A Soft key can be used to activate an additional status-display in the graphics
window instead of the graphics.
The colours for the status-window display can be altered by machine parameters.
6.4.1 Position display
The input resolutions for the TNCs are:
– TNC 415 B: 0.0001 mm or 0.0001°
– TNC 415 F and TNC 407: 0.001 mm or 0.001°
The display-step for the axis positions can be selected for specific axes by machine parameter.
Regardless of this selection the TNC always attempts to position precisely to 0.0001 mm or 0.0001°
(regardless of the grating period of the measuring system and the smallest voltage increment).
The most recently selected axis is displayed inversely. The PLC is informed (by a marker) which axis
has an inverse display. This information can be evaluated, for example, in connection with hand-
control equipment.
Machine parameter MP7285 can be used to select whether, in the positional-display, the tool axis
takes account of the tool length or not.
