Setting the measured value display
Designation of the coordinate axes: P49.*
Axis is coordinate axis A: P49.* = 65
Axis is coordinate axis B: P49.* = 66
Axis is coordinate axis C: P49.* = 67
Axis is coordinate axis U: P49.* = 85
Axis is coordinate axis V: P49.* = 86
Axis is coordinate axis W: P49.* = 87
Axis is coordinate axis X: P49.* = 88
Axis is coordinate axis Y: P49.* = 89
Axis is coordinate axis Z: P49.* = 90
Unit of measurement: P1 (User Parameter)
Display dimensions in millimeters (mm): P1 = 0
Display dimensions in inches (inch): P1 = 1
Angle display format: P8 (User Parameter)
Display in degrees, decimal: P8 = 0
Display in degrees / minutes / seconds: P8 = 1
Angle counting mode: P9.*
Display angles from 0° to 360°: P9 = 0
Display +/– 180°: P9 = 1
Display +/– ¥°: P9 = 2
The fourth axis can be combined with one of the three main
axes (X,Y, Z), for example with plungers. POSITIP adds or
subtracts the measured position values for the fourth axis and
main axis and displays the sum or difference as the "position
value" for the main axis.
Axis combination: P6
No axis combination (off): P6 = 0
The position values of axes 1 and 4 are added
together and the result displayed on axis 1 (1 + 4): P6 = 1
The position values of axes 2 and 4 are added
together and the result displayed on axis 2 (2 + 4): P6 = 2
The position values of axes 3 and 4 are added
together and the result displayed on axis 3 (3 + 4): P6 = 3
The position value of axis 4 is subtracted from axis 1
and the result displayed on axis 1 (1 – 4): P6 = 4
The position value of axis 4 is subtracted from axis 2
and the result displayed on axis 2 (2 – 4): P6 = 5
The position value of axis 4 is subtracted from axis 3
and the result displayed on axis 3 (3 – 4): P6 = 6
When diameter display is selected, a symbol (Ø) appears next
to the position value display, and the display value doubles.
For milling, only the radius display is needed.
Radius/diameter display: P3.* (User Parameter)
Display position values as "Radius": P3.* = 0
Display position values as "Diameter": P3.* = 1
