6.3 Status display
6.3.1 Position display
The display step for the axis positions can be selected for specific axes by machine parameter
MP7290. Regardless of this selection the programming and positioning of the axis position is always
carried out to 0.001 mm or 0.001° precisely.
The input resolution of the TNC 360 is 0.001 mm or 0.001°.
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.
MP7285 Calculation of the tool length in the position display of the tool axis
Input value: 0 or 1
0 = tool length ignored
1 = tool length taken into account
MP7290 Position display step
Input values: 0 to 4
0 = 0.001 mm or 0.001°
1 = 0.005 mm or 0.005°
2 = 0.010 mm or 0.010°
3 = 0.050 mm or 0.050°
